             CONDENSED NOTES TO THE COMBINED FINANCIAL STATEMENTS

                                   (Unaudited)


1.    ACCOUNTING POLICIES
      -------------------

      The combined balance sheets as of March 31, 2006,  combined  statements of
      operations  for the  three  months  ended  March 31,  2006 and  2005,  and
      combined  statements  of cash flows for the three  months  ended March 31,
      2006 and 2005 have been prepared by Geodyne  Resources,  Inc., the General
      Partner  of  the  limited   partnerships,   without  audit.  Each  limited
      partnership  is a general  partner in the related  Geodyne  Energy  Income
      Production  Partnership  in which Geodyne  Resources,  Inc.  serves as the
      managing partner.  Unless the context indicates otherwise,  all references
      to a  "Partnership"  or the  "Partnerships"  are references to the limited
      partnership and its related production partnership,  collectively, and all
      references to the "General  Partner" are references to the general partner
      of the limited  partnerships  and the managing  partner of the  production
      partnerships,  collectively.  In the opinion of  management  the financial
      statements referred to above include all necessary adjustments, consisting
      of normal recurring adjustments,  to present fairly the combined financial
      position at March 31, 2006,  the combined  results of  operations  for the
      three  months ended March 31, 2006 and 2005,  and the combined  cash flows
      for the three months ended March 31, 2006 and 2005.

      Information  and  footnote  disclosures  normally  included  in  financial
      statements  prepared in  accordance  with  generally  accepted  accounting
      principles  have been  condensed  or  omitted.  The  accompanying  interim
      financial  statements should be read in conjunction with the Partnerships'
      Annual Report on Form 10-K filed for the year ended December 31, 2005. The
      results  of  operations  for the  period  ended  March  31,  2006  are not
      necessarily indicative of the results to be expected for the full year.

      The  Limited  Partners'  net  income  or loss per unit is based  upon each
      $1,000 initial capital contribution.




                                      -12-





      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 costs 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  unit-of-production
      method.  The  Partnerships'  depletion,   depreciation,  and  amortization
      includes  estimated  dismantlement  and  abandonment  costs and  estimated
      salvage value of the equipment.

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


      ASSET RETIREMENT OBLIGATIONS
      ----------------------------

      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.
      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. During the year ended December 31,



                                      -13-




      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.

      The asset  retirement  obligation will be adjusted upwards each quarter in
      order to recognize accretion of the time-related  discount factor. For the
      three  months  ended March 31, 2006,  the I-D,  I-E, and I-F  Partnerships
      recognized approximately $1,000, $22,000, and $9,000, 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 three
      months ended March 31, 2006 and 2005 are as shown below.

ITEM 2.     MANAGEMENT'S  DISCUSSION  AND ANALYSIS OF FINANCIAL  CONDITION AND
            RESULTS OF OPERATIONS

USE OF FORWARD-LOOKING STATEMENTS AND ESTIMATES
- -----------------------------------------------

      This Quarterly 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
      Quarterly 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 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, and otherwise indicated.

GENERAL
- -------

      The  Partnerships  are engaged in the business of acquiring  and operating
      producing oil and gas properties located in the continental United States.
      In general, a Partnership acquired producing properties and did not engage
      in  development  drilling  or  enhanced  recovery  projects,  except as an
      incidental  part of the management of the producing  properties  acquired.
      Therefore,  the  economic  life  of  each  Partnership,  and  its  related
      Production Partnership, is limited to the period of time required to fully
      produce its acquired oil and gas  reserves.  The net proceeds from the oil
      and gas operations are distributed to the Limited Partners and the General
      Partner  in  accordance  with the terms of the  Partnerships'  partnership
      agreements.

LIQUIDITY AND CAPITAL RESOURCES
- -------------------------------

      The Partnerships began operations and investors were assigned their rights
      as Limited Partners,  having made capital contributions in the amounts and
      on the dates set forth below:

                                                            Limited
                                   Date of              Partner 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

      In general,  the amount of funds  available for  acquisition  of producing
      properties was equal to the capital contributions of the Limited Partners,
      less 15% for sales  commissions and  organization and management fees. All
      of the Partnerships have fully invested their capital contributions.

      Net proceeds from the  operations  less  necessary  operating  capital are
      distributed to the Limited Partners on a quarterly basis. Revenues and net
      proceeds of a Partnership  are largely  dependent  upon the volumes of oil
      and gas sold and the  prices  received  for  such oil and gas.  While  the
      General  Partner cannot predict  future  pricing  trends,  it believes the
      working  capital  available  as of  March  31,  2006  and the net  revenue
      generated from future operations will provide  sufficient  working capital
      to meet current and future obligations.

      Occasional expenditures for new wells or well recompletions, or workovers,
      however, may reduce or eliminate cash available for a particular quarterly
      cash distribution.

      Pursuant to the terms of the  Partnerships'  partnership  agreements  (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 their fourth two year extension  period to December
      31, 2007. As of the date of this Quarterly Report, the General Partner has
      not determined whether to further extend the term of any Partnership.




                                      -18-




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 Partnerships of the
      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  unit-of-production
      method.  The  Partnerships'  calculation of depreciation,  depletion,  and
      amortization  includes  estimated  dismantlement and abandonment costs and
      estimated  salvage  value  of  the  equipment.   When  complete  units  of
      depreciable  property  are  retired or sold,  the asset  cost and  related
      accumulated  depreciation  are eliminated with any gain or loss (including
      the elimination of the asset retirement  obligation)  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 exceeds 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 estimated  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.

      The Deferred  Charge on the Balance Sheets  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.



                                      -19-




      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 negotiated or contractual  payment to the underproduced
      party.


ASSET RETIREMENT OBLIGATIONS
- ----------------------------

      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.

PROVED RESERVES AND NET PRESENT VALUE
- -------------------------------------

      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  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.

      The  following  tables   summarize   changes  in  net  quantities  of  the
      Partnerships'  proved  reserves,  all of which are  located  in the United
      States, for the periods  indicated.  The proved reserves were estimated by
      petroleum  engineers  employed by affiliates of the Partnerships,  and are
      annually reviewed by an independent  engineering  firm.  "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. The following
      information includes certain gas balancing adjustments which cause the gas
      volume to differ from the reserve reports prepared by the General Partner.

      The  net  present   value  of  the   Partnerships'   reserves  may  change
      dramatically  as oil and gas prices  change or as  volumes  change for the
      reasons  described above.  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.

      The  following  table  indicates  the  estimated  net present value of the
      Partnerships'  proved reserves as of March 31, 2006 and December 31, 2005.
      Net present value  attributable to the  Partnerships'  proved reserves was
      calculated  on the basis of  current  costs  and  prices as of the date of
      estimation. Such prices were not escalated except in certain circumstances
      where  escalations were fixed and readily  determinable in accordance with
      applicable contract  provisions.  The table also indicates the oil and gas
      prices in effect on the dates  corresponding  to the  reserve  valuations.

RESULTS OF OPERATIONS
- ---------------------

      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 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:






                                      -23-




            *     Worldwide and domestic supplies of oil and natural gas;
            *     The ability of the  members  of the  Organization of Petroleum
                  Exporting   Countries  ("OPEC")  to agree to 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 the 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



                                      -24-




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

      Average price/Mcf                           $   6.99         $   5.98

      As shown in the table  above,  total oil and gas sales  decreased  $24,000
      (8.3%) for the three  months ended March 31, 2006 as compared to the three
      months  ended  March 31,  2005.  Of this  decrease,  $7,000  and  $61,000,
      respectively,  were  related to  decreases in volumes of oil and gas sold.
      These decreases were partially offset by increases of $12,000 and $32,000,
      respectively,  related to increases  in the average  prices of oil and gas
      sold.  Volumes of oil and gas sold  decreased  139 barrels and 10,246 Mcf,
      respectively, for the three months ended March 31, 2006 as compared to the
      three months ended March 31, 2005. The decrease in volumes of oil sold was
      primarily due to normal declines in production. The decrease in volumes of
      gas sold was  primarily  due to (i) normal  declines in  production,  (ii)
      positive prior period volume  adjustments made by the operators on several
      wells  during  the  three  months  ended  March  31,  2005,  and (iii) the
      shutting-in of one significant well due to production  difficulties during
      a portion of the three months ended March 31, 2006. As of the date of this
      Quarterly Report, the shut-in well has returned to production.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes) decreased  $10,000 for the three months ended March 31,
      2006 as compared to the three months ended March 31, 2005. As a percentage
      of oil and gas  sales,  these  expenses  decreased  to 16.9% for the three
      months  ended March 31, 2006 from 19.1% for the three  months  ended March
      31,  2005.  This  percentage  decrease  was  primarily  due to the  dollar
      decrease in oil and gas production expenses.



                                      -25-




      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      increased  $600  (9.4%)  for the three  months  ended  March  31,  2006 as
      compared to the three months ended March 31,  2005.  Of this  increase (i)
      $400 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  during  late 2005 and (ii) $400 was due to
      accretion  of  these  additional  asset  retirement   obligations.   These
      increases were partially offset by the decreases in volumes of oil and gas
      sold. As a percentage of oil and gas sales, this expense increased to 2.5%
      for the three  months  ended March 31, 2006 from 2.1% for the three months
      ended March 31, 2005.  This  percentage  increase was primarily due to (i)
      the dollar increase in  depreciation,  depletion,  and amortization of oil
      and gas properties and (ii) the increases in the average prices of oil and
      gas sold.

      General and administrative  expenses increased $2,000 (4.9%) for the three
      months  ended March 31, 2006 as compared to the three  months  ended March
      31, 2005. As a percentage of oil and gas sales,  these expenses  increased
      to 16.7% for the three  months  ended  March 31,  2006 from  14.6% for the
      three months ended March 31, 2005. This percentage  increase was primarily
      due to (i) the decrease in oil and gas sales and (ii) the dollar  increase
      in general and administrative expenses.

      The Limited  Partners have received cash  distributions  through March 31,
      2006  totaling   $18,052,175  or  250.91%  of  Limited  Partners'  capital
      contributions.

      As shown in the table above,  total oil and gas sales  decreased  $121,000
      (6.5%) for the three  months ended March 31, 2006 as compared to the three
      months  ended March 31,  2005.  Of this  decrease,  $65,000 and  $356,000,
      respectively,  were  related to  decreases in volumes of oil and gas sold.
      These  decreases  were  partially  offset by  increases  of  $128,000  and
      $172,000, respectively,  related to increases in the average prices of oil
      and gas sold.  Volumes of oil and gas sold  decreased  1,411  barrels  and
      60,261 Mcf,



                                      -26-




      respectively, for the three months ended March 31, 2006 as compared to the
      three months ended March 31, 2005. The decrease in volumes of oil sold was
      primarily due to normal declines in production. The decrease in volumes of
      gas sold was primarily due to (i) normal declines in production,  (ii) the
      shutting-in  of one  significant  well during the three months ended March
      31, 2006 due to  mechanical  problems,  and (iii)  positive  prior  period
      volume adjustments made by the operators on several wells during the three
      months ended March 31, 2005. As of the date of this Quarterly Report,  the
      shut-in  well is  expected  to return to  production  in the first half of
      2006.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  increased  $112,000 (37.0%) for the three months ended
      March 31, 2006 as compared to the three months ended March 31, 2005.  This
      increase was primarily due to (i) a reversal during the three months ended
      March 31, 2005 of approximately $89,000 of a charge previously accrued for
      a judgment and (ii) workover expenses incurred on several wells during the
      three months ended March 31, 2006.  As a percentage  of oil and gas sales,
      these  expenses  increased  to 24.1% for the three  months ended March 31,
      2006 from 16.4% for the three months ended March 31, 2005. This percentage
      increase  was  primarily  due to  the  dollar  increase  in  oil  and  gas
      production expenses.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      increased  $17,000  (40.1%) for the three  months  ended March 31, 2006 as
      compared to the three months ended March 31,  2005.  Of this  increase (i)
      $11,000 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 during late 2005 and (ii) $6,000 was due
      to  accretion  of these  additional  asset  retirement  obligations.  This
      increase  was also  due to (i)  downward  revisions  in the  estimates  of
      remaining  gas  reserves  since  March 31,  2005 and (ii) an  increase  in
      depletable oil and gas properties  during the three months ended March 31,
      2006 primarily due to drilling  activities in a large  unitized  property.
      These  increases were partially  offset by the decreases in volumes of oil
      and gas sold. As a percentage of oil and gas sales, this expense increased
      to 3.5% for the three  months ended March 31, 2006 from 2.3% for the three
      months ended March 31, 2005. This percentage increase was primarily due to
      the dollar increase in  depreciation,  depletion,  and amortization of oil
      and gas properties.

      General and administrative  expenses increased $3,000 (2.0%) for the three
      months  ended March 31, 2006 as compared to the three  months  ended March
      31, 2005. As a percentage of oil and gas sales,  these expenses  increased

      As shown in the table above,  total oil and gas sales remained  relatively
      constant for the three months ended March 31, 2006 and 2005.  Decreases of
      $38,000 and $85,000, respectively,  related to decreases in volumes of oil
      and gas sold  were  substantially  offset  by  increases  of  $58,000  and
      $60,000,  respectively,  related to increases in the average prices of oil
      and gas sold. Volumes of oil and gas sold decreased 819 barrels and 14,233
      Mcf,  respectively,  for the three months ended March 31, 2006 as compared
      to the three months  ended March 31, 2005.  The decrease in volumes of oil
      sold was primarily due to normal  declines in production.  The decrease in
      volumes  of  gas  sold  was  primarily  due  to  (i)  normal  declines  in
      production,  (ii) the shutting-in of one significant well during the three

      the first half of 2006.

      Oil and gas production  expenses  (including lease operating  expenses and

      March 31, 2006 as compared to the three months ended March 31, 2005.  This
      increase was primarily due to (i) a reversal during the three months ended

      these  expenses  increased  to 31.2% for the three  months ended March 31,
      2006 from 11.5% for the three months ended March 31, 2005. This percentage
      increase  was  primarily  due to  the  dollar  increase  in  oil  and  gas
      production expenses.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      increased  $6,000  (37.9%)  for the three  months  ended March 31, 2006 as
      compared to the three months ended March 31,  2005.  Of this  increase (i)
      $4,000 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  during late 2005 and (ii) $2,000 was due to
      accretion of these additional asset retirement obligations.  This increase
      was also  due to (i) an  increase  in  depletable  oil and gas  properties
      during the three  months  ended March 31, 2006  primarily  due to drilling
      activities in a large unitized property and (ii) downward revisions in the

ITEM 3.     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET
            RISK

            The Partnerships do not hold any market risk sensitive instruments.

ITEM 4.     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.
