                                    PART I.


ITEM 1.     BUSINESS

      General

      The Geodyne Energy Income Limited Partnership I-D (the "I-D Partnership"),
Geodyne  Energy Income  Limited  Partnership  I-E (the "I-E  Partnership"),  and
Geodyne  Energy  Income  Limited   Partnership   I-F  (the  "I-F   Partnership")
(collectively,  the  "Partnerships")  are limited  partnerships formed under the
Oklahoma  Revised Uniform Limited  Partnership Act. Each Partnership is composed
of public  investors as limited  partners (the "Limited  Partners")  and Geodyne
Resources, Inc. ("Geodyne"), a Delaware corporation, as the general partner. The
Partnerships commenced operations on the dates set forth below:

                                              Date of
                      Partnership           Activation
                      -----------       ------------------

                          I-D           March 4, 1986
                          I-E           September 10, 1986
                          I-F           December 16, 1986

      Immediately following  activation,  each Partnership invested as a general
partner in a separate  Oklahoma general  partnership which actually conducts the
Partnerships' production operations.  Geodyne serves as managing partner of such
general partnerships.  Unless the context indicates otherwise, all references to
any single  Partnership or all of the Partnerships in this Annual Report on Form
10-K ("Annual Report") are references to the Partnership and its related general
partnership,  collectively. In addition, unless the context indicates otherwise,
all references to the "General  Partner" in this Annual Report are references to
Geodyne as the general partner of the Partnerships,  and as the managing partner
of the related general partnerships.

      The  General  Partner  currently  serves as general  partner of 26 limited
partnerships,  including the Partnerships. The General Partner is a wholly-owned
subsidiary  of Samson  Investment  Company.  Samson  Investment  Company and its
various  corporate  subsidiaries,  including the General  Partner  (collectively
"Samson"),  are  primarily  engaged in the  production  and  development  of and
exploration  for oil and gas  reserves  and the  acquisition  and  operation  of
producing   properties.   At  December  31,  2005,  Samson  owned  interests  in
approximately 18,000 oil and gas wells located in 18 states of the United States
and the countries of Canada and Venezuela. At December 31, 2005, Samson operated
approximately 5,700 oil and gas wells located in 14 states of the United States,
as well as Canada and Venezuela.



                                      -4-




      The Partnerships are currently engaged in the business of owning interests
in producing oil and gas properties  located in the  continental  United States.
The Partnerships may also engage to a limited extent in development  drilling on
producing oil and gas  properties as required for the prudent  management of the
Partnerships.

      As limited partnerships,  the Partnerships have no officers, directors, or
employees. They rely instead on the personnel of the General Partner and Samson.
As of February  15,  2006,  Samson  employed  approximately  1,300  persons.  No
employees  are  covered by  collective  bargaining  agreements,  and  management
believes  that  Samson  provides a sound  employee  relations  environment.  For
information  regarding the executive officers of the General Partner,  see "Item
10. Directors and Executive Officers of the General Partner."

      The General Partner's and the Partnerships' principal place of business is
located at Samson Plaza,  Two West Second Street,  Tulsa,  Oklahoma  74103,  and
their telephone number is (918) 583-1791 or (888) 436-3963 [(888) GEODYNE].

      Pursuant to the terms of the partnership  agreements for the  Partnerships
(the  "Partnership  Agreements"),  the  Partnerships  would have  terminated  on
December 31, 1999. However, the Partnership  Agreements provide that the General
Partner may extend the term of each  Partnership  for up to five  periods of two
years each. The General Partner has extended the terms of the  Partnerships  for
the fourth  two-year  extension  period to December 31, 2007.  As of the date of
this Annual Report,  the General  Partner has not determined  whether to further
extend the term of any Partnership.


      Funding

      Although  the  Partnership  Agreements  permit each  Partnership  to incur
borrowings,   operations   and  expenses  are  currently   funded  out  of  each
Partnership's  revenues from oil and gas sales.  The General Partner may, but is
not required to, advance funds to a Partnership  for the same purposes for which
Partnership borrowings are authorized.


      Principal Products Produced and Services Rendered

      The  Partnerships'  sole  business  is  the  production  of,  and  related
incidental  development  of,  oil and gas.  The  Partnerships  do not  refine or
otherwise  process crude oil and  condensate.  The  Partnerships do not hold any
patents,  trademarks,  licenses,  or  concessions  and are  not a  party  to any
government  contracts.  The  Partnerships  have no  backlog of orders and do not
participate in research and development  activities.  The  Partnerships  are not
presently encountering shortages of oilfield tubular goods,



                                      -5-




compressors,  production  material,  or other  equipment.  However,  substantial
increases  in the global  price of steel as well as  increases in the prices for
oil and gas supplies and services will further  increase the costs of any future
workover, recompletion or drilling activities conducted by the Partnerships.


      Competition and Marketing

      The primary source of liquidity and Partnership cash  distributions  comes
from the net revenues  generated  from the sale of oil and gas produced from the
Partnerships'  oil and gas  properties.  The  level of net  revenues  is  highly
dependent  upon the total  volumes  of oil and  natural  gas  sold.  Oil and gas
reserves are depleting assets and will experience production declines over time,
thereby likely  resulting in reduced net revenues.  The level of net revenues is
also highly  dependent  upon the prices  received  for oil and gas sales,  which
prices  have  historically  been  very  volatile  and  may  continue  to be  so.
Additionally,  lower oil and natural gas prices may reduce the amount of oil and
gas that is economic to produce and reduce the  Partnerships'  revenues and cash
flow.  Various factors beyond the  Partnerships'  control will affect prices for
oil and natural gas, such as:

      *     Worldwide and domestic supplies of oil and natural gas;
      *     The  ability  of  the  members  of  the  Organization  of  Petroleum
            Exporting  Countries  ("OPEC") to agree upon and maintain oil prices
            and production quotas;
      *     Political  instability or armed conflict in oil-producing regions or
            around major shipping areas;
      *     The level of consumer demand and overall economic activity;
      *     The competitiveness of alternative fuels;
      *     Weather conditions and the impact of weather-related events;
      *     The availability of pipelines for transportation;
      *     Domestic and foreign government regulations and taxes; and
      *     Market expectations.

      It is not  possible to predict the future  direction of oil or natural gas
prices or whether the above  discussed  trends  will  remain.  Operating  costs,
including General and  Administrative  Expenses,  may not decline over time, may
increase or may experience only a gradual decline,  thus adversely affecting net
revenues as either  production  or oil and natural  gas prices  decline.  In any
particular  period,  net  revenues may also be affected by either the receipt of
proceeds from property sales or the incursion of additional costs as a result of
well workovers, recompletions, new well drilling, and other events.

      Significant Customers

      The  following  customers  accounted  for  ten  percent  or  more  of  the
Partnerships' oil and gas sales during the year ended December 31, 2005:

   Partnership               Customer                     Percentage
   -----------    ---------------------------------       ----------

       I-D        Chevron U.S.A., Inc. ("Chevron")           28.0%
                  Duke Energy Field Services, Inc.
                     ("Duke")                                22.1%

       I-F        Cinergy                                    16.4%
                  Duke                                       12.7%
                  BP                                         12.3%
                  Chevron                                    11.8%

      In  the  event  of  interruption  of  purchases  by  one  or  more  of the
Partnerships'  significant  customers  or the  cessation  or material  change in
availability  of  open  access  transportation  by  the  Partnerships'  pipeline
transporters,  the Partnerships may encounter  difficulty in marketing their gas
and in maintaining historic sales levels.  Management does not expect any of its
open access transporters to seek authorization to terminate their transportation
services.  Even  if the  services  were  terminated,  management  believes  that
alternatives  would  be  available  whereby  the  Partnerships  would be able to
continue to market their gas.

      The  Partnerships'  principal  customers  for  crude  oil  production  are
refiners and other companies  which have pipeline  facilities near the producing
properties  of the  Partnerships.  In the  event  pipeline  facilities  are  not
conveniently  available to  production  areas,  crude oil is usually  trucked by
purchasers to storage facilities.


      Oil, Gas, and Environmental Control Regulations

      Regulation  of Production  Operations -- The  production of oil and gas is
subject to  extensive  federal and state laws and  regulations  governing a wide
variety of matters, including the drilling and spacing of wells, allowable rates
of  production,  prevention  of  waste  and  pollution,  and  protection  of the
environment. In addition to the direct costs borne in complying



                                      -7-




with such  regulations,  operations  and  revenues may be impacted to the extent
that certain regulations limit oil and gas production to below economic levels.

      Regulation  of Sales and  Transportation  of Oil and Gas -- Sales of crude
oil and  condensate  are made by the  Partnerships  at market prices and are not
subject to price  controls.  The sale of gas may be subject to both  federal and
state laws and  regulations.  The provisions of these laws and  regulations  are
complex  and  affect  all who  produce,  resell,  transport,  or  purchase  gas,
including the  Partnerships.  Although  virtually all of the  Partnerships'  gas
production  is not subject to price  regulation,  other  regulations  affect the
availability of gas transportation  services and the ability of gas consumers to
continue to purchase or use gas at current levels. Accordingly, such regulations
may have a material  effect on the  Partnerships'  operations and projections of
future oil and gas production and revenues.

      Future  Legislation --  Legislation  affecting the oil and gas industry is
under  constant  review  for  amendment  or  expansion.  Because  such  laws and
regulations  are frequently  amended or  reinterpreted,  management is unable to
predict what  additional  energy  legislation  may be proposed or enacted or the
future cost and impact of complying with existing or future regulations.

      Regulation of the Environment -- The Partnerships'  operations are subject
to numerous laws and  regulations  governing the discharge of materials into the
environment or otherwise relating to environmental  protection.  Compliance with
such  laws  and  regulations,   together  with  any  penalties   resulting  from
noncompliance  may  increase  the cost of the  Partnerships'  operations  or may
affect  the  Partnerships'   ability  to  timely  complete  existing  or  future
activities.  Management  anticipates  that  various  local,  state,  and federal
environmental  control  agencies will have an  increasing  impact on oil and gas
operations.

      Insurance Coverage

      The  Partnerships  are  subject  to  all  of  the  risks  inherent  in the
exploration for and production of oil and gas,  including  blowouts,  pollution,
fires, and other casualties.  The Partnerships maintain insurance coverage as is
customary for entities of a similar size engaged in  operations  similar to that
of the  Partnerships,  but losses can occur from uninsurable risks or in amounts
in excess of existing insurance coverage.  For example,  many types of pollution
and  contamination  can exist,  undiscovered,  for long  periods of time and can
result in  substantial  environmental  liabilities  which are not  insured.  The
occurrence  of an event  which is not fully  covered by  insurance  could have a
material adverse effect on the Partnerships'  financial condition and results of
operations.


                                      -8-





ITEM 1A.    RISK FACTORS

      The following factors,  among others, could cause actual results to differ
materially  from those  contained  in  forward-looking  statements  made in this
report and presented  elsewhere from time to time.  Such factors,  among others,
may have a material adverse effect upon the  Partnerships'  business,  financial
condition, and results of operations.

      The  following  discussion of risk factors  should be read in  conjunction
with the  combined  financial  statements  and related  notes  included  herein.
Because of these and other  factors,  past financial  performance  should not be
considered an indication of future performance.


      Oil and Natural Gas Prices Fluctuate Due to a Number of
      -------------------------------------------------------
      Uncontrollable Factors, and Any Decline Will Adversely
      ------------------------------------------------------
      Affect the Partnerships' Financial Condition.
      ---------------------------------------------

      The  Partnerships'  results of  operations  depend  upon the  prices  they
receive for their oil and natural gas. We sell most of the Partnerships' oil and
natural gas liquids at current  market  prices  rather than through  fixed-price
contracts.  Historically, the markets for oil and natural gas have been volatile
and are likely to remain so. The prices we receive  depend upon  factors  beyond
our control, including:

         *  political instability or armed conflict in oil-producing regions;
         *  weather conditions;
         *  the supply of domestic and foreign oil and natural gas;
         *  the ability of members of OPEC to agree upon and maintain prices and
            production levels;
         *  the level of consumer demand and overall economic activity;
         *  worldwide economic demand;
         *  the price and availability of alternative fuels;
         *  domestic and foreign governmental regulations and taxes;
         *  the proximity to and capacity of transportation facilities; and
         *  the effect of worldwide energy conservation measures.

      Government  regulations,  such as regulation of natural gas transportation
and price controls,  can affect product prices in the long term.  These external
factors and the  volatile  nature of the energy  markets  make it  difficult  to
reliably estimate future prices of oil and natural gas.



                                      -9-




      Any  decline  in  oil  and  natural  gas  prices  adversely   affects  the
Partnerships'  financial  condition.  If the oil and  gas  industry  experiences
significant  price declines,  the Partnerships may not be able to maintain their
current level of cash  distributions.  See "Item 1 - Business - Competition  and
Marketing"  and "Item 7 -  Management's  Discussion  and  Analysis of  Financial
Condition and Results of Operations".


      Reserve Estimates Depend on Many Assumptions That May Turn
      ----------------------------------------------------------
      Out to be Inaccurate.  Any Material Inaccuracies in the
      -------------------------------------------------------
      Partnerships' Reserve Estimates or Underlying Assumptions
      ---------------------------------------------------------
      Could Cause the Quantities and Net Present Value of Their
      ---------------------------------------------------------
      Reserves to be Overstated.
      --------------------------

      Estimating  quantities of proved oil and natural gas reserves is a complex
process.  It requires  interpretations  of available  technical data and various
assumptions, including assumptions relating to economic factors. Any significant
inaccuracies  in these  interpretations  or  assumptions or changes of condition
could cause the quantities and net present value of the  Partnerships'  reserves
to be overstated.

      To prepare  estimates  of  economically  recoverable  oil and  natural gas
reserves and future net cash flows,  we analyze many variable  factors,  such as
historical  production from the area compared with  production  rates from other
producing areas. We also analyze available geological,  geophysical,  production
and engineering  data, and the extent,  quality and reliability of this data can
vary.  The process  also  involves  economic  assumptions  relating to commodity
prices,  production costs,  severance and excise taxes, capital expenditures and
workover  and  remedial  costs.  Actual  results  most likely will vary from our
estimates.  Any significant  variance could reduce the estimated  quantities and
present value of reserves shown in this annual report.

      You should not assume that the present value of future net cash flows from
the  Partnerships'  proved  reserves  shown in this Annual Report is the current
market value of their estimated oil and natural gas reserves. In accordance with
Securities  and Exchange  Commission  requirements,  the  Partnerships  base the
estimated  discounted future net cash flows from their proved reserves on prices
and costs on the date of the  estimate.  Actual  current  and future  prices and
costs may differ  materially  from those used in the earlier  net present  value
estimate,  and as a result, net present value estimates using current prices and
costs may be  significantly  less than the earlier estimate which is provided in
this annual  report.  See "Item 2 -  Properties-Proved  Reserves and Net Present
Value".

      Drilling Oil and Natural Gas Wells is a High-Risk Activity
      ----------------------------------------------------------
      and Subjects Us to a Variety of Factors That We Cannot
      ------------------------------------------------------
      Control.
      --------

      Drilling oil and natural gas wells,  including development wells, involves
numerous  risks,  including  the risk that the  Partnerships  may not  encounter
commercially  productive oil and natural gas reservoirs.  While the Partnerships
do not expend a significant portion of their capital on drilling activities,  to
the extent  they do drill wells this can be a  significant  risk factor to them.
They may not recover all or any portion of their  investment  in new wells.  The
presence  of   unanticipated   pressures  or   irregularities   in   formations,
miscalculations  or  accidents  may  cause  their  drilling   activities  to  be
unsuccessful  and  result  in a total  loss  of  investment.  Further,  drilling
operations  may be  curtailed,  delayed or  canceled as a result of a variety of
factors, including:

         *  unexpected drilling conditions;
         *  title problems;
         *  restricted access to land for drilling or laying pipeline;
         *  pressure or irregularities in formations;
         *  equipment failure or accidents;
         *  adverse weather conditions; and
         *  costs of, or shortages  or delays in the  availability of,  drilling
            rigs, tubular materials and equipment.


      The Marketability of the Partnerships' Production is
      ----------------------------------------------------
      Dependent upon Transportation and Processing Facilities Over
      ------------------------------------------------------------
      Which We Have No Control.
      -------------------------

      The marketability of the Partnerships' production depends in part upon the
availability, proximity and capacity of pipelines, natural gas gathering systems
and processing  facilities.  Any significant  change in market factors affecting
these  infrastructure  facilities  could harm their business.  The  Partnerships
deliver oil and natural gas through gathering systems and pipelines that they do
not  own.  These  facilities  may  be  temporarily  unavailable  due  to  market
conditions or mechanical reasons, or may not be available to us in the future.




                                      -11-




      Reliance on Third Party Operators
      ---------------------------------

      A  substantial  portion of the  Partnerships'  properties  are operated by
third  parties.   The  Partnerships  have  little,  if  any,  control  over  the
operational  decisions and costs associated with these properties.  In addition,
the  Partnerships  are totally  reliant on the third party  operators'  internal
controls associated with the operator's accounting for revenues and expenses.


      No Market for Units
      -------------------

      The Partnerships'  Units are not listed on any exchange or national market
system, and there is no established public trading market for the Units. You may
only sell your Units via (i) the General Partner's annual Repurchase Offer; (ii)
transfers  facilitated  by secondary  trading firms and matching  services;  and
(iii)  occasional  "4.9% tender offers" which are made for the Units.  Secondary
market   activity   for  the  Units  has  been  limited  and  varies  among  the
Partnerships.  See  "Item 5 - Market  for  Units  and  Related  Limited  Partner
Matters".


      Limited Life
      ------------

      The  Partnerships  are  currently  scheduled  to terminate on December 31,
2007.  Even  if  the  General   Partner   exercises  its  right  to  extend  the
Partnerships'  terms for one additional  two-year period,  the Partnerships will
terminate no later than December 31, 2009. Upon  termination  the  Partnerships'
assets will be sold.  There is no assurance  that the market for the sale of the
Partnerships' assets will be favorable at such time.


      The Partnerships are Subject to Complex Federal, State and
      ----------------------------------------------------------
      Local Laws and Regulations that Could Adversely Affect Their
      ------------------------------------------------------------
      Business
      ---------

      Extensive federal,  state and local regulation of the oil and gas industry
significantly  affects the  Partnerships'  operations.  In particular,  they are
subject to stringent environmental  regulations.  These regulations increase the
costs of planning, designing, drilling, installing, operating and abandoning oil
and natural gas wells and other related facilities. These regulations may become
more demanding in the future. Matters subject to regulation include:



                                      -12-




         *  discharge permits for drilling operations;
         *  drilling bonds;
         *  spacing of wells;
         *  unitization and pooling of properties;
         *  environmental protection;
         *  reports concerning operations; and
         *  taxation.

      Under these laws and regulations, the Partnerships could be liable for:

         *  personal injuries;
         *  property damage;
         *  oil spills;
         *  discharge of hazardous materials;
         *  reclamation costs;
         *  remediation and clean-up costs; and
         *  other environmental damages.

      While the Partnerships maintain insurance coverage customary for companies
similar to their size and operations, losses can occur from uninsurable risks or
in amounts in excess of existing insurance coverage. See "Item 1 - Business".


      Conflicts of Interest
      ---------------------

      Direct and indirect  conflicts of interests  exist among the  Partnerships
and among a Partnership and the General Partner and its affiliates.  The General
Partner and its  affiliates  engage in many aspects of the oil and gas business,
including  acting as a general  partner  of a number of  affiliated  oil and gas
limited  partnerships.  The  General  Partner and its  affiliates  may engage in
transactions  with a Partnership,  and  Partnerships  will frequently  engage in
transactions with other oil and gas limited partnerships.  These conflicts could
relate  to  the  sale  of oil  and  gas  properties,  the  determination  of the
Partnerships'  Repurchase  Prices,  and the determination of whether to continue
the Partnerships past their scheduled termination date of December 31, 2007. See
"Item 13 - Certain Relationships and Related Transactions".


      Payments to the General Partner
      -------------------------------

      The General Partner receives reimbursements for General and Administrative
Expenses.  The  General  Partner  also  receives  a share  of  Partnership  cash
distributions.  See "Item 11 - Executive  Compensation"  and "Item 8 - Financial
Statements and Supplementary Data".




                                      -13-




      Financial Capability of General Partner
      ---------------------------------------

      The General Partner has limited  financial  resources.  Contingencies  may
arise which will require  funding beyond its financial  resources.  Even if such
financial  resources are available,  the General Partner is not required to lend
money or to fund any financial obligations of the Partnerships.


      Liability and Indemnification of General Partner and Related
      ------------------------------------------------------------
      Parties
      -------

      Although the General Partner  generally will be liable for the obligations
of the Partnerships, the Partnership Agreements provide that the claims of third
parties will be initially  satisfied from  Partnership  assets.  The Partnership
Agreements also provide,  subject to certain  conditions,  that the Partnerships
will reimburse  (i.e.  "indemnify")  the General  Partner and its affiliates for
certain costs, claims and expenses.

- ----------

(1)   The  designation  of a well  as an oil  well  or gas  well  is made by the
      General Partner based on the relative amount of oil



                                      -14-




      and  gas  reserves  for  the  well.  Regardless  of a  well's  oil  or gas
      designation, it may produce oil, gas, or both oil and gas.
(2)   As used in this Annual  Report,  "gross  well" refers to a well in which a
      working interest is owned;  accordingly,  the number of gross wells is the
      total number of wells in which a working interest is owned.
(3)   As  used  in this  Annual  Report,  "net  well"  refers  to the sum of the
      fractional  working  interests  owned in gross wells.  For example,  a 15%
      working interest in a well represents one gross well, but 0.15 net well.


      Drilling Activities

      During the year ended  December 31,  2005,  the  Partnerships  directly or
indirectly participated in the drilling activities described below:

      Oil and Gas Production, Revenue, and Price History

      The following tables set forth certain historical  information  concerning
the oil  (including  condensates)  and  gas  production,  net of all  royalties,
overriding  royalties,  and other third party  interests,  of the  Partnerships,
revenues   attributable  to  such   production,   and  certain  price  and  cost
information.  As used in the following tables, direct operating expenses include
lease operating  expenses and production  taxes. In addition,  gas production is
converted to oil equivalents at the rate of six Mcf per barrel, representing the
estimated  relative energy content of gas and oil, which rate is not necessarily
indicative of the relationship of oil and gas prices.  The respective  prices of
oil and gas are  affected  by market and other  factors in  addition to relative
energy content.

      Proved Reserves and Net Present Value

      The following table sets forth each Partnership's estimated proved oil and
gas reserves  and net present  value  therefrom  as of December  31,  2005.  The
schedule  of  quantities  of proved oil and gas  reserves  was  prepared  by the
General  Partner in accordance  with the rules  prescribed by the Securities and
Exchange  Commission (the "SEC").  Certain  reserve  information was reviewed by
Ryder Scott Company,  L.P. ("Ryder Scott"), an independent petroleum engineering
firm. As used throughout this Annual Report,  "proved  reserves" refers to those
estimated  quantities of crude oil, gas, and gas liquids  which  geological  and
engineering  data  demonstrate  with  reasonable  certainty to be recoverable in
future  years from known oil and gas  reservoirs  under  existing  economic  and
operating conditions.




                                      -19-




      Net present  value  represents  estimated  future gross cash flow from the
production and sale of proved reserves,  net of estimated oil and gas production
costs (including production taxes, ad valorem taxes, and operating expenses) and
estimated  future  development  costs,  discounted at 10% per annum. Net present
value  attributable to the  Partnerships'  proved reserves was calculated on the
basis of current  costs and prices at December  31,  2005.  Such prices were not
escalated  except in  certain  circumstances  where  escalations  were fixed and
readily determinable in accordance with applicable contract provisions.  Oil and
gas  prices at  December  31,  2005  ($61.06  per  barrel  and  $10.08  per Mcf,
respectively)  were  substantially  higher than the prices in effect on December
31, 2004 ($43.36 per barrel and $6.02 per Mcf,  respectively).  This increase in
oil  and  gas  prices  has  caused  the  estimates  of  remaining   economically
recoverable reserves, as well as the values placed on said reserves, at December
31, 2005 to be higher than such  estimates and values at December 31, 2004.  The
prices  used  in  calculating   the  net  present  value   attributable  to  the
Partnerships'  proved reserves do not necessarily  reflect market prices for oil
and gas  production  subsequent to December 31, 2005. In fact, as of the date of
this Annual  Report,  natural gas prices have  declined  significantly  from the
December  31,  2005  price.  There can be no  assurance  that the prices used in
calculating  the net  present  value of the  Partnerships'  proved  reserves  at
December 31, 2005 will actually be realized for such production.

      The process of  estimating  oil and gas  reserves  is  complex,  requiring
significant  subjective  decisions in the  evaluation  of available  geological,
engineering,  and  economic  data  for  each  reservoir.  The  data  for a given
reservoir may change substantially over time as a result of, among other things,
additional development activity, production history, and viability of production
under varying economic conditions;  consequently, it is reasonably possible that
material  revisions to existing reserve  estimates may occur in the near future.
Although  every  reasonable  effort has been made to ensure  that these  reserve
estimates represent the most accurate assessment  possible,  the significance of
the  subjective  decisions  required and variances in available data for various
reservoirs  make these  estimates  generally  less precise than other  estimates
presented in connection with financial statement disclosures.

      Title to Oil and Gas Properties

      Management believes that the Partnerships have satisfactory title to their
oil and gas properties.  Record title to all of the Partnerships'  properties is
held by either the Partnerships or Geodyne Nominee Corporation,  an affiliate of
the General Partner.

      Title to the  Partnerships'  properties  is subject to customary  royalty,
overriding  royalty,   carried,   working,   and  other  similar  interests  and
contractual  arrangements  customary in the oil and gas  industry,  to liens for
current taxes not yet due, and to other  encumbrances.  Management believes that
such burdens do not materially detract from the value of such properties or from
the Partnerships' interest therein or materially interfere with their use in the
operation of the Partnerships' business.



ITEM 3.     LEGAL PROCEEDINGS

      To the knowledge of the General  Partner,  neither the General Partner nor
the Partnerships or their properties are subject to any litigation,  the results
of which  would  have a  material  effect on the  Partnerships'  or the  General
Partner's financial condition or operations.



ITEM 4.     SUBMISSION OF MATTERS TO A VOTE OF LIMITED PARTNERS

      There were no matters  submitted to a vote of the Limited  Partners of any
Partnership during 2005.



                                    PART II.

ITEM 5.     MARKET FOR UNITS AND RELATED LIMITED PARTNER MATTERS

      As of March 1, 2006, the number of Units  outstanding  and the approximate
number of Limited Partners of record in the Partnerships were as follows:

                                                 Number of
                                 Number of        Limited
               Partnership         Units          Partners

                   I-D             7,195              578
                   I-E            41,839            2,196
                   I-F            14,321              674



                                      -24-




      Units were initially sold for a price of $1,000.  The Units are not traded
on any  exchange  and there is no public  trading  market for them.  The General
Partner is aware of certain transfers of Units between unrelated  parties,  some
of which are facilitated by secondary  trading firms and matching  services.  In
addition,  as further  described  below, the General Partner is aware of certain
"4.9% tender  offers"  which have been made for the Units.  The General  Partner
believes  that the  transfers  between  unrelated  parties have been limited and
sporadic  in number  and  volume.  Other  than  trades  facilitated  by  certain
secondary trading firms and matching  services,  no organized trading market for
Units  exists  and none is  expected  to  develop.  Due to the  nature  of these
transactions, the General Partner has no verifiable information regarding prices
at which Units have been  transferred.  Further,  a transferee  may not become a
substitute Limited Partner without the consent of the General Partner.

      Pursuant to the terms of the Partnership  Agreements,  the General Partner
is  obligated  to  annually  issue a  repurchase  offer  which  is  based on the
estimated future net revenues from the Partnerships'  reserves and is calculated
pursuant to the terms of the Partnership  Agreements.  Such repurchase  offer is
recalculated  monthly  in order to reflect  cash  distributions  to the  Limited
Partners and  extraordinary  events.  The following table sets forth the General
Partner's repurchase offer per Unit as of the periods indicated.  For purpose of
this Annual Report,  a Unit  represents an initial  subscription  of $1,000 to a
Partnership.

      The Partnership Agreements also provide for a right of presentment ("Right
of  Presentment")  whereby the General  Partner is required,  upon  request,  to
purchase up to 10% of a Partnership's  outstanding  Units at a price  calculated
pursuant to the terms of the Partnership Agreements and based on the liquidation
value of the limited  partnership  interest,  with a  reduction  for 70% of cash
distributions  that have been received prior to the transfer of the  partnership
interest. The following table sets forth the Right of Presentment price per Unit
as of the periods indicated.

      In addition to the  repurchase  offer and Right of  Presentment  described
above,  some of the Partnerships  have been subject to "4.9% tender offers" from
several  third  parties.  The General  Partner  does not know the terms of these
offers or the prices received by the Limited Partners who accepted these offers.


      Cash Distributions

      Cash  distributions  are primarily  dependent  upon a  Partnership's  cash
receipts from the sale of oil and gas  production and cash  requirements  of the
Partnership.  Distributable cash is determined by the General Partner at the end
of each calendar  quarter and distributed to the Limited Partners within 45 days
after the end of the quarter.  Distributions are restricted to cash on hand less
amounts  required  to be  retained  out of such cash as  determined  in the sole
judgment of the General  Partner to pay costs,  expenses,  or other  Partnership
obligations whether accrued or anticipated to accrue. In certain instances,  the
General  Partner may not distribute the full amount of cash receipts which might
otherwise be available  for  distribution  in an effort to equalize or stabilize
the amounts of quarterly  distributions.  Any available  amounts not distributed
are  invested  and the  interest  or income  thereon is for the  accounts of the
Limited Partners.

      The  following  is a summary  of cash  distributions  paid to the  Limited
Partners during 2004 and 2005 and the first quarter of 2006:

ITEM 7.     MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
            AND RESULTS OF OPERATIONS

      Use of Forward-Looking Statements and Estimates

      This Annual Report contains certain forward-looking  statements. The words
"anticipate,"  "believe,"  "expect,"  "plan," "intend,"  "estimate,"  "project,"
"could," "may," and similar expressions are intended to identify forward-looking
statements.  Such statements reflect  management's current views with respect to
future  events and  financial  performance.  This Annual  Report  also  includes
certain information which is, or is based upon, estimates and assumptions.  Such
estimates and assumptions  are  management's  efforts to accurately  reflect the
condition and operation of the Partnerships.

      Use of  forward-looking  statements and estimates and assumptions  involve
risks and uncertainties which include, but are not limited to, the volatility of
oil and gas prices, the uncertainty of reserve  information,  the operating risk
associated with oil and gas properties  (including the risk of personal  injury,
death, property damage, damage to the well or producing reservoir, environmental
contamination,  and other  operating  risks),  the  prospect of changing tax and
regulatory laws, the availability and capacity of processing and  transportation
facilities,  the  accuracy of third party  payments  and  billings,  the general
economic  climate,  the supply and price of foreign  imports of oil and gas, the
level of consumer product demand,  and the price and availability of alternative
fuels.  Should  one or more of these  risks  or  uncertainties  occur or  should
estimates or  underlying  assumptions  prove  incorrect,  actual  conditions  or
results  may vary  materially  and  adversely  from those  stated,  anticipated,
believed, estimated, or otherwise indicated.


      General Discussion

      The following  general  discussion  should be read in conjunction with the
analysis  of  results  of  operations  provided  below.  The  primary  source of
liquidity  and  Partnership  cash  distributions  comes  from  the net  revenues
generated from the sale of oil and gas produced from the  Partnerships'  oil and
gas  properties.  The level of net revenues is highly  dependent upon the prices
received  for oil and gas  sales,  which  prices  have  historically  been  very
volatile  and may  continue  to be so.  Additionally,  lower oil and natural gas
prices  may reduce the  amount of oil and gas that is  economic  to produce  and
reduce the  Partnerships'  revenues and cash flow.  Various  factors  beyond the
Partnerships' control will affect prices for oil and natural gas, such as:



                                      -31-





      *     Worldwide and domestic supplies of oil and natural gas;
      *     The  ability of the members of OPEC to agree upon and  maintain  oil
            prices and production quotas;
      *     Political  instability or armed conflict in oil-producing regions or
            around major shipping areas;
      *     The level of consumer demand and overall economic activity;
      *     The competitiveness of alternative fuels;
      *     Weather conditions and the impact of weather-related events;
      *     The availability of pipelines for transportation;
      *     Domestic and foreign government regulations and taxes; and
      *     Market expectations.

      It is not  possible to predict the future  direction of oil or natural gas
prices or whether the above  discussed  trends  will  remain.  Operating  costs,
including General and  Administrative  Expenses,  may not decline over time, may
increase, or may experience only a gradual decline, thus adversely affecting net
revenues as either  production  or oil and natural  gas prices  decline.  In any
particular  period,  net  revenues may also be affected by either the receipt of
proceeds from property sales or the incursion of additional costs as a result of
well workovers, recompletions, new well drilling, and other events.

      In addition to pricing, the level of net revenues is also highly dependent
upon the total  volumes of oil and natural gas sold.  Oil and gas  reserves  are
depleting  assets and will  experience  production  declines over time,  thereby
likely  resulting  in  reduced  net  revenues.  Despite  this  general  trend of
declining production,  several factors can cause the volumes of oil and gas sold
to increase,  remain  relatively  constant,  or decrease at an even greater rate
over a given period. These factors include, but are not limited to:

      *     geophysical conditions which cause an acceleration of the decline in
            production,
      *     the  shutting  in of wells (or the  opening  of  previously  shut-in
            wells) due to low oil and gas  prices (or high oil and gas  prices),
            mechanical  difficulties,  loss of a market  or  transportation,  or
            performance of workovers,  recompletions, or other operations in the
            well,
      *     prior period volume  adjustments  (either positive or negative) made
            by operators of the properties,
      *     adjustments in ownership or rights to production in accordance  with
            agreements governing the operation or ownership of the well (such as
            adjustments that occur at payout or due to gas balancing), and
      *     completion of enhanced recovery  projects which increase  production
            for the well.

Many of these  factors  are very  significant  as related to a single well or as
related to many wells over a short period of time.



                                      -32-




However,  due to the large  number  of wells  owned by the  Partnerships,  these
factors  are  generally  not  material  as  compared  to the  normal  decline in
production experienced on all remaining wells.


      Results of Operations

      An  analysis  of the  change  in net oil and gas  operations  (oil and gas
sales,  less lease operating  expenses and production taxes) is presented in the
tables  following  "Results  of  Operations"  under the heading  "Average  Sales
Prices,  Production  Volumes,  and Average  Production  Costs."  Following  is a
discussion  of each  Partnership's  results  of  operations  for the year  ended
December  31, 2005 as compared to the year ended  December  31, 2004 and for the
year ended December 31, 2004 as compared to the year ended December 31, 2003.

      Total oil and gas sales increased  $318,000 (34.1%) in 2005 as compared to
2004.  Of this  increase  $53,000 and  $276,000,  respectively,  were related to
increases  in the  average  prices of oil and gas  sold.  These  increases  were
partially  offset by a decrease  of $15,000  related to a decrease in volumes of
gas sold.  Volumes of oil sold increased 105 barrels,  while volumes of gas sold
decreased 2,801 Mcf in 2005 as compared to 2004.

      The decrease in volumes of gas sold was primarily  due to normal  declines
in  production.  This  decrease  was  partially  offset  by (i)  the  successful
completion  of several new wells  during  late 2004 and early to mid 2005,  (ii)
positive prior period volume  adjustments made by the operators on several wells
during 2005,  and (iii) the first  receipt of revenues on one  significant  well
during early 2005.

      Average  oil and gas prices  increased  to $54.82 per barrel and $7.29 per
Mcf,  respectively,   in  2005  from  $40.06  per  barrel  and  $5.38  per  Mcf,
respectively, in 2004.

      Oil and gas production  expenses  (including lease operating  expenses and
production  taxes)  increased  $47,000 (27.7%) in 2005 as compared to 2004. This
increase was  primarily due to (i) an increase in  production  taxes  associated
with the  increase  in oil and gas  sales,  (ii)  positive  prior  period  lease
operating  expense  adjustments  made on several  wells during  2005,  and (iii)
workover expenses incurred on several other wells during 2005. As a



                                      -33-




percentage of oil and gas sales,  these expenses decreased to 17.4% in 2005 from
18.3% in 2004.

      Depreciation,   depletion,  and  amortization  ("DD&A")  of  oil  and  gas
properties  increased  $8,000  (25.2%)  in 2005 as  compared  to  2004.  Of this
increase (i) $10,000 was due to the depletion of additional capitalized costs of
oil and gas properties as a result of the upward revision in the estimate of the
asset  retirement  obligations,  of which $8,000 was related to previously fully
depleted wells,  and (ii) $1,000 was due to accretion of these  additional asset
retirement  obligations.  This  increase was also due to two  significant  wells
being fully depleted  during 2005 due to the lack of remaining  reserves.  These
increases were partially offset by (i) several wells being fully depleted during
2004 due to the lack of  remaining  reserves  and (ii) upward  revisions  in the
estimates  of  remaining  oil and gas reserves  since  December  31, 2004.  As a
percentage  of oil and gas sales,  this  expense  decreased to 3.3% in 2005 from
3.6% in 2004.

      General and  administrative  expenses  increased  $7,000 (6.6%) in 2005 as
compared to 2004. As a percentage of oil and gas sales, these expenses decreased
to 9.1% in 2005 from 11.4% in 2004, primarily due to the increase in oil and gas
sales.

      Total oil and gas sales  decreased  $76,000  (7.6%) in 2004 as compared to
2003.  Of this  decrease  $8,000 and  $164,000,  respectively,  were  related to
decreases in volumes of oil and gas sold.  These decreases were partially offset
by increases of $39,000 and $57,000,  respectively,  related to increases in the
average  prices of oil and gas sold.  Volumes of oil and gas sold  decreased 294
barrels and 32,913 Mcf, respectively,  in 2004 as compared to 2003. The decrease
in volumes of gas sold was  primarily  due to (i) normal  declines in production
and (ii) the shutting-in of one significant well during 2004 in order to perform
a workover.

      Average  oil and gas prices  increased  to $40.06 per barrel and $5.38 per
Mcf,  respectively,   in  2004  from  $28.87  per  barrel  and  $4.99  per  Mcf,
respectively, in 2003.

      Oil and gas production  expenses  (including lease operating  expenses and
production  taxes)  decreased  $14,000  (7.6%) in 2004 as compared to 2003. As a
percentage of oil and gas sales,  these expenses  remained  constant at 18.3% in
2004 and 2003.

      DD&A  of oil and  gas  properties  decreased  $39,000  (54.1%)  in 2004 as
compared to 2003.  This decrease was primarily due to (i) one  significant  well
being fully depleted in 2003 due to the lack of remaining  reserves and (ii) the
decreases in volumes of oil and gas sold.  These decreases were partially offset
by several other wells being fully depleted in 2004 due to the lack of remaining
reserves.  As a percentage of oil and gas sales,  this expense decreased to 3.6%
in 2004 from 7.2% in 2003,  primarily due to the dollar  decrease in DD&A of oil
and gas properties.

      General and administrative  expenses remained  relatively constant in 2004
and 2003.  As a percentage  of oil and gas sales,  these  expenses  increased to
11.4% in 2004 from 10.5% in 2003.

      Total oil and gas sales increased  $1,890,000  (31.8%) in 2005 as compared
to 2004. Of this increase $641,000 and $1,605,000, respectively, were related to
increases  in the  average  prices of oil and gas  sold.  These  increases  were
partially offset by decreases of $187,000 and $169,000, respectively, related to
decreases in volumes of oil and gas sold.  Volumes of oil and gas sold decreased
4,982 barrels and 32,222 Mcf, respectively, in 2005 as compared to 2004.

      The  decrease  in  volumes  of oil sold was  primarily  due to (i)  normal
declines in production and (ii) a negative prior period volume  adjustment  made
by the operator on one significant  well during 2005. The decrease in volumes of
gas sold was primarily due to normal  declines in production.  This decrease was
partially offset by (i) an increase in production on several wells following the
successful  workover  of those wells  during mid 2004 and early  2005,  (ii) the
successful  completion  of several  new wells  during late 2004 and early to mid
2005, and (iii) positive prior period volume  adjustments  made by the operators
on several other wells during 2005.

      Average  oil and gas prices  increased  to $53.74 per barrel and $7.28 per
Mcf,  respectively,   in  2005  from  $37.56  per  barrel  and  $5.23  per  Mcf,
respectively, in 2004.

      Oil and gas production  expenses  (including lease operating  expenses and
production  taxes) increased  $197,000 (14.0%) in 2005 as compared to 2004. This
increase was  primarily due to (i) workover  expenses  incurred on several wells
during 2005, (ii) an increase in production  taxes  associated with the increase
in oil



                                      -35-




and  gas  sales,  and  (iii)  positive  prior  period  lease  operating  expense
adjustments  made on several  other wells  during  2005.  These  increases  were
partially offset by (i) a reversal during 2005 of $89,000 of a charge previously
accrued for a judgment  and (ii)  workover  expenses  incurred on several  wells
during 2004. As a percentage of oil and gas sales,  these expenses  decreased to
20.4% in 2005 from 23.6% in 2004. This percentage  decrease was primarily due to
the increase in oil and gas sales.

      Depreciation,   depletion,  and  amortization  ("DD&A")  of  oil  and  gas
properties  increased  $174,000  (89.2%) in 2005 as  compared  to 2004.  Of this
increase (i) $162,000 was due to the depletion of additional  capitalized  costs
of oil and gas properties as a result of the upward  revision in the estimate of
the asset  retirement  obligations,  of which $128,000 was related to previously
fully depleted wells,  and (ii) $21,000 was due to accretion of these additional

the  estimates of remaining oil and gas reserves  since  December 31, 2004. As a
percentage  of oil and gas sales,  this  expense  increased to 4.7% in 2005 from
3.3%  in  2004,  primarily  due to the  dollar  increase  in DD&A of oil and gas
properties.

      General and administrative  expenses remained  relatively constant in 2005
and 2004. As a percentage of oil and gas sales, these expenses decreased to 6.5%
in 2005 from 8.5% in 2004, primarily due to the increase in oil and gas sales.

2003. Of this  decrease  $242,000 and  $810,000,  respectively,  were related to
decreases in volumes of oil and gas sold.  These decreases were partially offset
by increases of $446,000 and $277,000, respectively, related to increases in the
average prices of oil and gas sold.  Volumes of oil and gas sold decreased 8,766
barrels and 165,627 Mcf, respectively, in 2004 as compared to 2003.

      The  decrease  in  volumes  of oil sold was  primarily  due to (i)  normal

respectively, in 2003.

      Oil and gas production  expenses  (including lease operating  expenses and
production taxes) remained  relatively  constant in 2004 and 2003. A decrease in
lease operating expenses associated with the decreases in volumes of oil and gas
sold was substantially offset by (i) workover expenses incurred on several wells
during  2004 and (ii)  repair  and  maintenance  expenses  incurred  on  another
significant  well  during  2004.  As a  percentage  of oil and gas sales,  these

      Liquidity and Capital Resources

      Net  proceeds  from  operations  less  necessary   operating  capital  are
distributed to the Limited  Partners on a quarterly  basis.  See "Item 5. Market
for Units and Related Limited Partner Matters." The net proceeds from production
generally are not  reinvested in  productive  assets,  except to the extent that
producing  wells are  improved,  where  methods  are  employed  to  permit  more
efficient recovery of reserves,  or where identified  developmental  drilling or
recompletion opportunities are pursued, thereby resulting in a positive economic
impact. Assuming 2005



                                      -41-




production levels for future years, the Partnerships'  proved reserve quantities
at December 31, 2005 would have the following remaining lives:

                  Partnership       Gas-Years      Oil-Years
                  -----------       ---------      ---------

                      I-D              10.8           20.0
                      I-E              10.5           13.4
                      I-F              10.4           13.8

These life of reserves estimates are based on the current estimates of remaining
oil and gas reserves. See "Item 2. Properties" for a discussion of these reserve
estimates.  Any  increase or decrease in the oil and gas prices at December  31,
2005 may cause an increase or decrease in the estimated  life of said  reserves.
As discussed below,  the Partnerships  must terminate no later than December 31,
2009, which is four years from December 31, 2005.

      The   Partnerships'   available   capital   from  the  Limited   Partners'
subscriptions  has been spent on oil and gas properties,  and there should be no
further material capital resource commitments for any of the Partnerships in the
future. The Partnerships have no debt commitments. Cash for operational purposes
will be provided by current oil and gas production. During 2005, 2004, and 2003,
the  Partnerships  expended no capital on oil and gas acquisition or exploration
activities.  However, during those years the Partnerships expended the following
amounts on oil and gas developmental activities, primarily well recompletion and
developmental drilling:

               Partnership      2005        2004        2003
               -----------    --------    --------    --------

                  I-D         $ 25,894    $ 22,991    $ 39,589
                  I-E          166,942     116,369     201,567
                  I-F           80,581      57,596      92,849

While these expenditures may reduce or eliminate cash available for a particular
quarterly cash distribution,  the General Partner believes that these activities
are necessary for the prudent  operation of the properties and  maximization  of
their value to the Partnerships.

      The Partnerships sold certain oil and gas properties during 2004 and 2003.
No such sales occurred during 2005. The sale of the Partnerships' properties was
made by the General  Partner  after giving due  consideration  to both the offer
price and the General  Partner's  estimate of the  property's  remaining  proved
reserves and future  operating  costs.  Net  proceeds  from the sale of any such
properties  were  included  in  the  calculation  of  the   Partnerships'   cash
distributions for the quarter immediately following the Partnerships' receipt of
the proceeds. The amount



                                      -42-




of such proceeds from the sales of oil and gas properties during 2005, 2004, and
2003, were as follows:


            Partnership        2005        2004        2003
            -----------       ------      -------     -------

                I-D           $  -        $ 3,715     $   101
                I-E              -         17,915      27,972
                I-F              -          5,546      20,097

      Over the years,  as part of the  normal  course of  business,  some of the
Partnerships'  interests  in wells  have  been  sold,  generally  at oil and gas
auctions.  Given the generally  favorable  current  environment  for oil and gas
dispositions,  it is possible that the Partnerships  will increase the number of
properties to be sold. In the event of sales,  any net proceeds are  distributed
as soon as possible after the disposition.  Future  production,  costs, and cash
flow will be reduced as properties are sold.

      There can be no  assurance  as to the amount of the  Partnerships'  future
cash distributions. The Partnerships' ability to make cash distributions depends
primarily upon the level of available  cash flow generated by the  Partnerships'
operating  activities,  which will be affected (either positively or negatively)
by many factors beyond the control of the  Partnerships,  including the price of
and demand for oil and gas and other  market and  economic  conditions.  Even if
prices and costs remain stable,  the amount of cash available for  distributions
will decline over time (as the volume of production  from  producing  properties
declines) since the Partnerships are not generally replacing  production through
acquisitions of producing properties and extensive drilling.

      The  General  Partner  expects  general  and  administrative  expenses  to
increase substantially during 2006 and 2007 due to costs required to comply with
Section 404 of the  Sarbanes-Oxley  Act of 2002. Such anticipated  increase will
reduce cash available for  distribution.  The General Partner expects at least a
portion of this anticipated  increase in general and administrative  expenses to
continue in years beyond 2007.

      Pursuant  to the terms of the  Partnership  Agreements,  the  Partnerships
would have terminated on December 31, 1999. However, the Partnership  Agreements
provide that the General Partner may extend the term of each  Partnership for up
to five periods of two years each. The General Partner has extended the terms of
the Partnerships for the fourth two-year  extension period to December 31, 2007.
As of the date of this Annual  Report,  the General  Partner has not  determined
whether to further extend the term of any Partnership.



                                      -43-




      Off-Balance Sheet Arrangements

      The Partnerships do not have any off-balance sheet arrangements.


      Tabular Disclosure of Contractual Obligations

      The  Partnerships  do not have  any  contractual  obligations  of the type
required to be disclosed under this heading.


      Critical Accounting Policies

      The  Partnerships  follow the successful  efforts method of accounting for
their  oil  and  gas  properties.  Under  the  successful  efforts  method,  the
Partnerships  capitalize all property  acquisition  costs and development  costs
incurred in  connection  with the further  development  of oil and gas reserves.
Property  acquisition  costs include costs incurred by the  Partnerships  or the
General  Partner  to  acquire  producing  properties,  including  related  title
insurance or examination costs, commissions,  engineering,  legal and accounting
fees, and similar costs directly related to the acquisitions,  plus an allocated
portion of the General Partner's  property screening costs. The acquisition cost
to the Partnership of properties  acquired by the General Partner is adjusted to
reflect  the net cash  results of  operations,  including  interest  incurred to
finance the  acquisition,  for the period of time the properties are held by the
General Partner.

      Depletion of the cost of producing oil and gas properties, amortization of
related intangible  drilling and development costs, and depreciation of tangible
lease and well  equipment are computed on the  units-of-production  method.  The
Partnerships' calculation of depreciation,  depletion, and amortization includes
estimated  dismantlement and abandonment costs, net of estimated salvage values.
When complete units of depreciable  property are retired or sold, the asset cost
and  related  accumulated  depreciation  are  eliminated  with  any gain or loss
reflected in income.  When less than complete units of depreciable  property are
retired or sold, the proceeds are credited to oil and gas properties.

      The  Partnerships  evaluate the  recoverability  of the carrying  costs of
their  proved oil and gas  properties  for each oil and gas field  (rather  than
separately for each well).  If the  unamortized  costs of oil and gas properties
within a field  exceed the  expected  undiscounted  future  cash flows from such
properties,  the cost of the properties is written down to fair value,  which is
determined by using the discounted  future cash flows from the  properties.  The
risk that the Partnerships will be required to record  impairment  provisions in
the future increases as oil and gas prices decrease.



                                      -44-





      The  Deferred  Charge on the  Balance  Sheets  included  in Item 8 of this
Annual Report represents costs deferred for lease operating expenses incurred in
connection  with  the  Partnerships'   underproduced  gas  imbalance  positions.
Conversely, the Accrued Liability represents charges accrued for lease operating
expenses  incurred  in  connection  with  the  Partnerships'   overproduced  gas
imbalance  positions.  The rate used in  calculating  the  Deferred  Charge  and
Accrued Liability is the annual average production costs per Mcf.

      The Partnerships' oil and condensate production is sold, title passed, and
revenue recognized at or near the Partnerships'  wells under short-term purchase
contracts  at  prevailing  prices  in  accordance  with  arrangements  which are
customary  in  the  oil  and  gas  industry.  Sales  of  gas  applicable  to the
Partnerships'  interest in producing  oil and gas leases are recorded as revenue
when  the gas is  metered  and  title  transferred  pursuant  to the  gas  sales
contracts covering the Partnerships' interest in gas reserves. During such times
as a  Partnership's  sales of gas exceed its pro rata ownership in a well,  such
sales are recorded as revenues  unless  total sales from the well have  exceeded
the Partnership's share of estimated total gas reserves underlying the property,
at which time such excess is recorded as a liability.  The rates per Mcf used to
calculate  this  liability  are  based on the  average  gas  price for which the
Partnerships are currently settling this liability.  These amounts were recorded
as gas  imbalance  payables  in  accordance  with the  sales  method.  These gas
imbalance payables will be settled by either gas production by the underproduced
party in excess of current  estimates of total gas reserves for the well or by a
negotiated or contractual payment to the underproduced party.

      The Partnerships' wells must be properly plugged and abandoned after their
oil and gas  reserves  are  exhausted.  The  Partnerships  follow  FAS No.  143,
"Accounting  for Asset  Retirement  Obligations"  in  accounting  for the future
expenditures that will be necessary to plug and abandon these wells. FAS No. 143
requires the estimated plugging and abandonment  obligations to be recognized in
the  period  in which  they are  incurred  (i.e.  when  the well is  drilled  or
acquired)  if a  reasonable  estimate  of  fair  value  can  be  made  and to be
capitalized as part of the carrying amount of the well.


      New Accounting Pronouncements

      The  Partnerships  are  not  aware  of  any  recently  issued   accounting
pronouncements that would have an impact on the Partnerships'  future results of
operations and financial position.



                                      -45-




      Inflation and Changing Prices

      Prices obtained for oil and gas production  depend upon numerous  factors,
including the extent of domestic and foreign production, foreign imports of oil,
market  demand,  domestic  and  foreign  economic  conditions  in  general,  and
governmental  regulations  and tax laws.  Inflationary  pressure on drilling and
operating  costs have impacted the operating and drilling  costs incurred by the
Partnerships.  This  pressure is  expected  to continue to the extent  commodity
prices remain at their current levels. Oil and gas prices have fluctuated during
recent years and generally have not followed the same pattern as inflation.  See
"Item 2. Properties - Oil and Gas Production, Revenue, and Price History."



ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

      The Partnerships do not hold any market risk sensitive instruments.



ITEM 8.     FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

      The financial  statements  and  supplementary  data are indexed in Item 15

      None.



ITEM 9A.    CONTROLS AND PROCEDURES

      As of the  end of  this  period  covered  by this  report,  the  principal
executive officer and principal financial officer conducted an evaluation of the
Partnerships'  disclosure controls and procedures (as defined in Rules 13a-15(e)
and  15d-15(e)  under the  Securities  and Exchange Act of 1934).  Based on this
evaluation,  such officers concluded that the Partnerships'  disclosure controls
and procedures are effective to ensure that information required to be disclosed
by the  Partnerships  in  reports  filed  under the  Exchange  Act is  recorded,
processed,  summarized,  and  reported  accurately  and within the time  periods
specified in the Securities and Exchange Commission rules and forms.

      Section 16(a) Beneficial Ownership Reporting Compliance

      To the knowledge of the Partnerships  and the General Partner,  there were
no officers,  directors, or ten percent owners who were delinquent filers during
2005 of reports  required  under  Section 16 of the  Securities  Exchange Act of
1934.


      Audit Committee Financial Expert

      The  Partnerships  are not  required by SEC  regulations  or  otherwise to
maintain an audit  committee.  The board of  directors  of the  General  Partner
consists of one person and therefore serves as its audit committee. There is not
an audit committee financial expert, as defined in the SEC regulations,  serving
on the General Partner's board of directors.


      Code of Ethics

      The General  Partner has adopted a Code of Ethics which  applies to all of
its  executive  officers,  including  those persons who perform the functions of
principal  executive  officer,   principal  financial  officer,   and  principal
accounting  officer.  The Partnerships  will provide,  free of charge, a copy of
this Code of Ethics to any person upon  receipt of a written  request  mailed to
Geodyne  Resources,  Inc.,  Investor  Services,  Samson  Plaza,  Two West Second
Street, Tulsa, OK 74103. Such request must include the address to which the Code
of Ethics should be mailed.



ITEM 11.    EXECUTIVE COMPENSATION

      The General  Partner and its  affiliates are reimbursed for actual general
and  administrative  costs and operating costs incurred and  attributable to the
conduct of the business affairs and operations of the Partnerships,  computed on
a cost basis,  determined  in  accordance  with  generally  accepted  accounting
principles.  Such reimbursed  costs and expenses  allocated to the  Partnerships
include office rent, secretarial, employee compensation and benefits, travel and
communication costs, fees for professional  services,  and other items generally
classified  as general or  administrative  expense.  When actual costs  incurred
benefit other  Partnerships and affiliates,  the allocation of costs is based on
the  relationship of the  Partnerships'  reserves to the total reserves owned by
all  Partnerships  and  affiliates.  The  amount of general  and  administrative
expense allocated to the General Partner and its affiliates which was charged to
each  Partnership  for 2005,  2004,  and 2003,  is set forth in the table below.
Although the actual  costs  incurred by the General  Partner and its  affiliates
have fluctuated during the three years



                                      -48-




presented, the amount charged to the Partnerships have not fluctuated every year
due to expense limitations imposed by the Partnership Agreements.

      None  of  the  officers  or  directors  of  the  General  Partner  receive
compensation  directly from the  Partnerships.  The  Partnerships  reimburse the
General  Partner  or its  affiliates  for that  portion  of such  officers'  and
directors'   salaries  and  expenses   attributable  to  time  devoted  by  such
individuals  to the  Partnerships'  activities  based on the  allocation  method
described above. The following tables indicate the approximate amount of general
and  administrative  expense  reimbursement  attributable to the salaries of the
directors,  officers,  and employees of the General  Partner and its  affiliates
during 2005, 2004, and 2003:

      Affiliates  of  the  Partnerships   serve  as  operator  of  some  of  the
Partnerships'  wells.  The General  Partner  contracts with such  affiliates for
services as operator of the wells. As operator,  such affiliates are compensated
at rates  provided  in the  operating  agreements  in effect and  charged to all
parties to such agreement. Such compensation may occur both prior and subsequent
to the  commencement  of  commercial  marketing of production of oil or gas. The
dollar amount of such compensation paid by the Partnerships to the affiliates is
impossible to quantify as of the date of this Annual Report.

      Samson  maintains  necessary  inventories of new and used field equipment.
Samson  may  have  provided  some of this  equipment  for  wells  in  which  the
Partnerships  have an interest.  This  equipment was provided at prices or rates
equal  to or  less  than  those  normally  charged  in the  same  or  comparable
geographic  area by unaffiliated  persons or companies  dealing at arm's length.
The operators of these wells billed the Partnerships for a portion of such costs
based upon the Partnerships' interest in the well.


ITEM 12.    SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

      The following table provides information as to the beneficial ownership of
the Units as of the date of filing  this  Annual  Report by (i) each  beneficial
owner of more than five percent of the issued and  outstanding  Units,  (ii) the
directors and officers of the General Partner, and (iii) the General Partner and
its  affiliates.  The address of each of such persons is Samson Plaza,  Two West
Second Street, Tulsa, Oklahoma 74103.

   the General Partner (4 persons)                    4,864 (34.0%)



ITEM 13.    CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

      The General  Partner and certain of its  affiliates  engage in oil and gas
activities  independently  of the  Partnerships  which  result in  conflicts  of
interest that cannot be totally  eliminated.  The allocation of acquisition  and
drilling  opportunities and the nature of the compensation  arrangements between
the  Partnerships  and the General  Partner also create  potential  conflicts of
interest.  An affiliate of the Partnerships owns some of the Partnerships' Units
and  therefore  has an identity of interest  with other  Limited  Partners  with
respect to the operations of the Partnerships.

      In order to attempt to assure  limited  liability for Limited  Partners as
well as an orderly  conduct  of  business,  management  of the  Partnerships  is
exercised  solely by the General Partner.  The Partnership  Agreements grant the
General Partner broad discretionary  authority with respect to the Partnerships'
participation  in  drilling  prospects  and  expenditure  and  control of funds,
including  borrowings.  These  provisions  are  similar  to those  contained  in
prospectuses   and   partnership   agreements  for  other  public  oil  and  gas
partnerships.  Broad  discretion as to general  management  of the  Partnerships
involves  circumstances  where the General Partner has conflicts of interest and
where  it  must  allocate  costs  and  expenses,  or  opportunities,  among  the
Partnerships and other competing interests.

      The  General  Partner  does  not  devote  all of its  time,  efforts,  and
personnel exclusively to the Partnerships.  Furthermore, the Partnerships do not
have  any  employees,   but  instead  rely  on  the  personnel  of  Samson.  The
Partnerships thus compete with Samson (including other oil and gas partnerships)



                                      -54-




for the time and  resources  of such  personnel.  Samson  devotes  such time and
personnel  to  the  management  of the  Partnerships  as  are  indicated  by the
circumstances and as are consistent with the General Partner's fiduciary duties.

      Affiliates of the Partnerships are solely responsible for the negotiation,
administration,  and  enforcement of oil and gas sales  agreements  covering the
Partnerships'  leasehold  interests.  Because affiliates of the Partnerships who
provide  services to the  Partnerships  have  fiduciary or other duties to other
members of Samson,  contract amendments and negotiating  positions taken by them
in their  effort  to  enforce  contracts  with  purchasers  may not  necessarily
represent  the  positions  that  the  Partnerships  would  take if they  were to
administer their own contracts without involvement with other members of Samson.
On the  other  hand,  management  believes  that the  Partnerships'  negotiating
strength  and  contractual  positions  have  been  enhanced  by  virtue of their
affiliation with Samson.

ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

TO THE PARTNERS

GEODYNE ENERGY INCOME LIMITED PARTNERSHIP I-D
GEODYNE PRODUCTION PARTNERSHIP I-D

      In our opinion,  the accompanying  combined balance sheets and the related
combined  statements of operations,  changes in partners'  capital (deficit) and
cash flows present  fairly,  in all material  respects,  the combined  financial
position of the  Geodyne  Energy  Income  Limited  Partnership  I-D, an Oklahoma
limited partnership, and Geodyne Production Partnership I-D, an Oklahoma general
partnership,  at December 31, 2005 and 2004,  and the combined  results of their
operations  and their cash flows for each of the three years in the period ended
December 31, 2005, in conformity with accounting  principles  generally accepted
in  the  United  States  of  America.   These   financial   statements  are  the
responsibility of the Partnerships' management. Our responsibility is to express
an opinion on these financial  statements based on our audits.  We conducted our
audits of these  financial  statements in  accordance  with the standards of the
Public Company  Accounting  Oversight  Board (United  States).  Those  standards
require that we plan and perform the audit to obtain reasonable  assurance about
whether the financial  statements  are free of material  misstatement.  An audit
includes  examining,  on a test  basis,  evidence  supporting  the  amounts  and
disclosures in the financial  statements,  assessing the  accounting  principles
used and  significant  estimates made by management,  and evaluating the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for the opinion expressed above.

      As discussed in Note 1 of Notes to the Combined Financial Statements under
the  heading  "Asset  Retirement  Obligation,"  effective  January  1,  2003 the
Partnerships  changed  the manner in which  they  account  for asset  retirement
obligations.

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

TO THE PARTNERS

GEODYNE ENERGY INCOME LIMITED PARTNERSHIP I-E
GEODYNE PRODUCTION PARTNERSHIP I-E

      In our opinion,  the accompanying  combined balance sheets and the related
combined  statements of operations,  changes in partners'  capital (deficit) and
cash flows present  fairly,  in all material  respects,  the combined  financial
position of the  Geodyne  Energy  Income  Limited  Partnership  I-E, an Oklahoma
limited partnership, and Geodyne Production Partnership I-E, an Oklahoma general
partnership,  at December 31, 2005 and 2004,  and the combined  results of their
operations  and their cash flows for each of the three years in the period ended
December 31, 2005, in conformity with accounting  principles  generally accepted
in  the  United  States  of  America.   These   financial   statements  are  the
responsibility of the Partnerships' management. Our responsibility is to express
an opinion on these financial  statements based on our audits.  We conducted our
audits of these  financial  statements in  accordance  with the standards of the
Public Company  Accounting  Oversight  Board (United  States).  Those  standards
require that we plan and perform the audit to obtain reasonable  assurance about
whether the financial  statements  are free of material  misstatement.  An audit
includes  examining,  on a test  basis,  evidence  supporting  the  amounts  and
disclosures in the financial  statements,  assessing the  accounting  principles
used and  significant  estimates made by management,  and evaluating the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for the opinion expressed above.

      As discussed in Note 1 of Notes to the Combined Financial Statements under
the  heading  "Asset  Retirement  Obligation,"  effective  January  1,  2003 the
Partnerships  changed  the manner in which  they  account  for asset  retirement
obligations.

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

TO THE PARTNERS

GEODYNE ENERGY INCOME LIMITED PARTNERSHIP I-F
GEODYNE PRODUCTION PARTNERSHIP I-F

      In our opinion,  the accompanying  combined balance sheets and the related
combined  statements of operations,  changes in partners'  capital (deficit) and
cash flows present  fairly,  in all material  respects,  the combined  financial
position of the  Geodyne  Energy  Income  Limited  Partnership  I-F, an Oklahoma
limited partnership, and Geodyne Production Partnership I-F, an Oklahoma general
partnership,  at December 31, 2005 and 2004,  and the combined  results of their
operations  and their cash flows for each of the three years in the period ended
December 31, 2005, in conformity with accounting  principles  generally accepted
in  the  United  States  of  America.   These   financial   statements  are  the
responsibility of the Partnerships' management. Our responsibility is to express
an opinion on these financial  statements based on our audits.  We conducted our
audits of these  financial  statements in  accordance  with the standards of the
Public Company  Accounting  Oversight  Board (United  States).  Those  standards
require that we plan and perform the audit to obtain reasonable  assurance about
whether the financial  statements  are free of material  misstatement.  An audit
includes  examining,  on a test  basis,  evidence  supporting  the  amounts  and
disclosures in the financial  statements,  assessing the  accounting  principles
used and  significant  estimates made by management,  and evaluating the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for the opinion expressed above.

      As discussed in Note 1 of Notes to the Combined Financial Statements under
the  heading  "Asset  Retirement  Obligation,"  effective  January  1,  2003 the
Partnerships  changed  the manner in which  they  account  for asset  retirement
obligations.

             GEODYNE ENERGY INCOME PROGRAM I LIMITED PARTNERSHIPS
                  Notes to the Combined Financial Statements
             For the Years Ended December 31, 2005, 2004, and 2003


1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      Organization and Nature of Operations

      The Geodyne Energy Income Limited  Partnerships (the  "Partnerships") were
formed  pursuant  to a public  offering  of  depositary  units  ("Units").  Upon
formation,  investors became limited partners (the "Limited  Partners") and held
Units issued by each Partnership. Geodyne Resources, Inc. is the general partner
of the  Partnerships.  Each  Partnership  is a general  partner  in the  related
Geodyne Energy Income  Production  Partnership  (collectively,  the  "Production
Partnership") in which Geodyne  Resources,  Inc. serves as the managing partner.
Limited Partner capital contributions were contributed to the related Production
Partnerships   for  investment  in  producing  oil  and  gas   properties.   The
Partnerships  were activated on the following  dates with the following  Limited
Partner capital contributions:

                                                         Limited
                                                         Partner
                                    Date of              Capital
            Partnership           Activation          Contributions
            -----------       ------------------      --------------

               I-D            March 4, 1986            $ 7,194,700
               I-E            September 10, 1986        41,839,400
               I-F            December 16, 1986         14,320,900

      The  Partnerships'  original  termination  date  under  their  partnership
agreements was December 31, 1999. The General  Partner has extended the terms of
the  Partnerships for their fourth two-year period to December 31, 2007 pursuant
to its right to extend the term of each  Partnership  for up to five  periods of
two years each.

      For  purposes  of  these  financial   statements,   the  Partnerships  and
Production  Partnerships are collectively  referred to as the "Partnerships" and
the general  partner and managing  partner are  collectively  referred to as the
"General Partner."

      An affiliate of the General  Partner owned the following Units at December
31, 2005:



                                      F-19





                               Number of        Percent of
            Partnership       Units Owned    Outstanding Units
            -----------       -----------    -----------------
               I-D               2,199                30.6%
               I-E              12,006                28.7%
               I-F               4,859                33.9%

      The  Partnerships'  sole business is the development and production of oil
and gas.  Substantially  all of the  Partnerships'  gas production is being sold
regionally  on the "spot  market." Due to the highly  competitive  nature of the
spot market, prices on the spot market are subject to wide seasonal and regional
pricing  fluctuations.  In  addition,  such  spot  market  sales  are  generally
short-term in nature and are dependent  upon obtaining  transportation  services
provided  by  pipelines.   The   Partnerships'  oil  is  sold  at  or  near  the
Partnerships'   wells  under   short-term   purchase   contracts  at  prevailing
arrangements  which are customary in the oil industry.  The prices  received for
the  Partnerships'  oil  and gas  are  subject  to  influences  such  as  global
consumption and supply trends.


      Allocation of Costs and Revenues

      The Partnerships have achieved payout and therefore the combination of the
allocation  provisions in each Partnership's  limited partnership  agreement and
each  Production   Partnership's   partnership  agreement   (collectively,   the
"Partnership  Agreement") results in allocations of costs and income between the
Limited Partners and General Partner as follows:




                                      F-20




                                            General     Limited

         perties                              15%         85%
     All other income                         15%         85%

- ----------
(1)   The allocations in the table result  generally from the combined effect of
      the allocation provisions in the Partnership Agreements.  For example, the
      costs  incurred in  development  drilling  are  allocated  85.8586% to the
      limited  partnership  and 14.1414% to the managing  partner.  The 85.8586%
      portion of these costs allocated to the limited  partnership,  when passed
      through the limited  partnership,  is further allocated 99% to the limited
      partners  and 1% to the  general  partner.  In  this  manner  the  Limited
      Partners  are  allocated  85% of such  costs and the  General  Partner  is
      allocated 15% of such costs.


      Basis of Presentation

      These  financial   statements   reflect  the  combined  accounts  of  each
Partnership  after the  elimination of all  inter-partnership  transactions  and
balances.


      Cash and Cash Equivalents

      The Partnerships consider all highly liquid investments with a maturity of
three months or less when purchased to be cash equivalents. Cash equivalents are
not insured, which cause the Partnerships to be subject to risk.




                                      F-21




      Credit Risk

      Accrued  oil and gas sales  which  are due from a  variety  of oil and gas
purchasers  subject the  Partnerships to a concentration of credit risk. Some of
these purchasers are discussed in Note 3 - Major Customers.


      Oil and Gas Properties

      The  Partnerships  follow the successful  efforts method of accounting for
their  oil  and  gas  properties.  Under  the  successful  efforts  method,  the
Partnerships  capitalize all property  acquisition  costs and development  costs
incurred in  connection  with the further  development  of oil and gas reserves.
Property  acquisition  costs include costs incurred by the  Partnerships  or the
General  Partner  to  acquire  producing  properties,  including  related  title
insurance or examination costs, commissions,  engineering,  legal and accounting
fees, and similar costs directly related to the acquisitions,  plus an allocated
portion of the General Partner's  property screening costs. The acquisition cost
to the Partnerships of properties acquired by the General Partner is adjusted to
reflect  the net cash  results of  operations,  including  interest  incurred to
finance the  acquisition,  for the period of time the properties are held by the
General Partner.

      Depletion of the cost of producing oil and gas properties, amortization of
related intangible  drilling and development costs, and depreciation of tangible
lease and well  equipment are computed on the  units-of-production  method.  The
Partnerships' depletion,  depreciation,  and amortization includes dismantlement
and  abandonment  costs,  net of  estimated  salvage  value.  The  depreciation,
depletion,  and  amortization  rates,  which  include  accretion  of  the  asset
retirement  obligation,  per equivalent  barrel of oil produced during the years
ended December 31, 2005, 2004, and 2003, were as follows:

            Partnership        2005        2004        2003
            -----------       -----       -----       -----

                I-D           $1.51       $1.19       $2.15
                I-E            2.17        1.08        2.24
                I-F            3.20        1.18        1.22

      When complete units of depreciable property are retired or sold, the asset
cost,  related   accumulated   depreciation,   and  remaining  asset  retirement
obligation,  are eliminated with any gain or loss reflected in income. When less
than complete  units of  depreciable  property are retired or sold, the proceeds
are credited to oil and gas properties.

      The  Partnerships  evaluate the  recoverability  of the carrying  costs of
their proved oil and gas properties at the field level.



                                      F-22




If the  unamortized  costs of oil and gas  properties  within a field exceed the
expected  undiscounted  future cash flows from such properties,  the cost of the
properties  is written  down to fair  value,  which is  determined  by using the
discounted future cash flows from the properties.  No impairment provisions were
recorded by the Partnerships during the three years ended December 31, 2005. The
risk that the Partnerships will be required to record  impairment  provisions in
the future increases as oil and gas prices decrease.


      Deferred Charge

      The Deferred Charge represents costs deferred for lease operating expenses
incurred  in  connection  with the  Partnerships'  underproduced  gas  imbalance
positions.  The rate used in  calculating  the  deferred  charge is the  average
annual production costs per Mcf. At December 31, 2005 and 2004, cumulative total
gas sales  volumes  for  underproduced  wells  were less than the  Partnerships'
pro-rata  share  of total  gas  production  from  these  wells by the  following
amounts:

                                  2005                      2004
                         ---------------------     ----------------------
      Partnership          Mcf         Amount        Mcf          Amount
      -----------        -------      --------     -------       --------

          I-D            146,979      $ 77,179     157,314       $ 82,606
          I-E            591,655       394,160     636,910        424,309
          I-F            246,365       302,265     266,208        326,610


      Accrued Liability - Other

      The Accrued  Liability  - Other at  December  31, 2004 for the I-E and I-F
Partnerships  represents a charge accrued for the payment of a judgment  related
to plugging liabilities. The decrease in Accrued Liability - Other from December
31,  2004 to December  31,  2005 was due to a ruling  made by the Texas  Supreme
Court on April 8, 2005 that the Partnerships did not owe this liability.


      Accrued Liability

      The Accrued  Liability  represents  charges  accrued  for lease  operating
expenses  incurred  in  connection  with  the  Partnerships'   overproduced  gas
imbalance  positions.  The rate used in calculating the accrued liability is the
average  annual  production  costs  per Mcf.  At  December  31,  2005 and  2004,
cumulative  total  gas  sales  volumes  for  overproduced   wells  exceeded  the
Partnerships'  pro-rata  share of total gas  production  from these wells by the
following amounts:



                                      F-23

          I-E           184,473        122,896     236,623      157,638
          I-F            93,100        114,225     113,386      139,114


      Oil and Gas Sales and Gas Imbalance Payable

      The Partnerships' oil and condensate production is sold, title passed, and
revenue recognized at or near the Partnerships'  wells under short-term purchase
contracts  at  prevailing  prices  in  accordance  with  arrangements  which are
customary in the oil  industry.  Sales of gas  applicable  to the  Partnerships'
interest in producing oil and gas leases are recorded as revenue when the gas is
metered and title transferred  pursuant to the gas sales contracts  covering the
Partnerships'  interest in gas  reserves.  During such times as a  Partnership's
sales of gas exceed its pro rata ownership in a well, such sales are recorded as
revenue unless total sales from the well have exceeded the  Partnership's  share
of estimated  total gas reserves  underlying  the  property,  at which time such
excess is  recorded as a  liability.  The rates per Mcf used to  calculate  this
liability  are based on the  average gas prices for which the  Partnerships  are
currently  settling this liability.  At December 31, 2005 and 2004,  total sales
exceeded the Partnerships' share of estimated total gas reserves as follows:


                                2005                       2004
                         -------------------        ------------------
      Partnership         Mcf        Amount          Mcf       Amount
      -----------        ------     --------        ------    --------

          I-D            21,978     $ 32,967        23,058    $ 34,587
          I-E            74,682      112,023        78,175     117,263
          I-F            24,115       36,173        25,240      37,860

These  amounts were recorded as gas  imbalance  payables in accordance  with the
sales  method.  These gas  imbalance  payables  will be  settled  by either  gas
production by the  underproduced  party in excess of current  estimates of total
gas  reserves  for the well or by a  negotiated  or  contractual  payment to the
underproduced party.



                                      F-24




      The Partnerships have not entered into any hedging or derivative contracts
in connection with their production and sale of oil and gas.


      General and Administrative Overhead

      The General  Partner and its  affiliates are reimbursed for actual general
and  administrative  costs  incurred  and  attributable  to the  conduct  of the
business affairs and operations of the Partnerships.


      Use of Estimates in Financial Statements

      The  preparation  of financial  statements  in conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates. Further, the
deferred charge,  the gas imbalance payable,  the asset retirement  obligations,
and the accrued  liability all involve  estimates which could materially  differ
from the actual  amounts  ultimately  realized or incurred in the near term. Oil
and gas reserves  (see Note 4) also involve  significant  estimates  which could
materially differ from the actual amounts ultimately realized.


      Asset Retirement Obligation

      The Partnerships' wells must be properly plugged and abandoned after their
oil and gas reserves are exhausted.  FAS No. 143 requires the estimated plugging
and  abandonment  obligations  to be  recognized in the period in which they are
incurred (i.e. when the well is drilled or acquired) if a reasonable estimate of
fair value can be made and to be capitalized  as part of the carrying  amount of
the well.  Estimated  abandonment  dates will be revised in the future  based on
changes to related economic lives, which vary with product prices and production
costs.  Estimated  plugging  costs  may also be  adjusted  to  reflect  changing
industry  experience.  On January 1, 2003, the Partnerships  adopted FAS No. 143
"Accounting  for Asset  Retirement  Obligations"  and  recorded  an  increase in
capitalized cost of oil and gas properties, an increase (decrease) in net income
for the cumulative  effect of the change in accounting  principle,  and an asset
retirement   obligation.   During  the  year  ended   December  31,  2005,   the
Partnerships'  asset  retirement  obligations  were  revised  upward  due  to an
increase in both the labor and rig costs  associated with plugging  wells.  Cash
flows would not be affected until wells are actually plugged and abandoned.



                                      F-25






      The asset retirement  obligation is adjusted upwards each quarter in order
to recognize  accretion of the time-related  discount factor. For the year ended
December 31, 2005, the I-D, I-E, and I-F Partnerships  recognized  approximately
$13,000, $214,000, and $125,000,  respectively,  of an increase in depreciation,
depletion,  and  amortization  expense,  which was comprised of accretion of the
asset retirement obligation and depletion of the increase in capitalized cost of
oil and gas properties.

      The components of the change in asset retirement obligations for the years
ended December 31, 2005 and 2004 are as shown below.

      Income Taxes

      Income or loss for income tax  purposes  is  includable  in the income tax
returns of the partners.  Accordingly,  no recognition  has been given to income
taxes in these financial statements.

2. TRANSACTIONS WITH RELATED PARTIES

      The  Partnerships  reimburse  the  General  Partner  for the  general  and
administrative  overhead applicable to the Partnerships,  based on an allocation
of actual costs  incurred by the General  Partner.  When actual  costs  incurred
benefit other  Partnerships and affiliates,  the allocation of costs is based on
the  relationship of the  Partnerships'  reserves to the total reserves owned by
all  Partnerships  and affiliates.  The General Partner believes this allocation
method is reasonable.  Although the actual costs incurred by the General Partner
and its affiliates have fluctuated during the three years presented, the amounts
charged  to the  Partnerships  have not  fluctuated  every  year due to  expense
limitations imposed by the Partnership Agreements. The following is a summary of
payments made to the General Partner or its affiliates by the  Partnerships  for
general and administrative overhead costs for the years ended December 31, 2005,
2004, and 2003:

      Affiliates  of the  Partnerships  operate  certain  of  the  Partnerships'
properties  and  their  policy  is to bill the  Partnerships  for all  customary
charges and cost reimbursements associated with these activities,  together with
any compressor rentals, consulting, or other services provided.
