                     PART I. - FINANCIAL INFORMATION


Item 1.   Financial Statements

The  unaudited  condensed financial statements included  herein  have
been  prepared  by  the Registrant (herein also referred  to  as  the
"Partnership")  in  accordance  with  generally  accepted  accounting
principles   for   interim  financial  information   and   with   the
instructions  to  Form  10-Q  and  Rule  10-01  of  Regulation   S-X.
Accordingly, they do not include all of the information and footnotes
required  by  generally accepted accounting principles  for  complete
financial  statements.  In the opinion of management, all adjustments
necessary  for a fair presentation have been included and  are  of  a
normal recurring nature.  The financial statements should be read  in
conjunction  with  the  audited financial statements  and  the  notes
thereto for the year ended December 31, 2002, which are found in  the
Registrant's  Form 10-K/A Report for 2002 filed with  the  Securities
and  Exchange  Commission.   The  December  31,  2002  balance  sheet
included herein has been taken from the Registrant's 2002 Form 10-K/A
Report.  Operating results for the three month period ended March 31,
2003  are  not  necessarily indicative of the  results  that  may  be
expected for the full year.

Introductory Note - Statement of Financial Accounting Standard No.
143
The  Partnership implemented SFAS No. 143 effective January  1,  2003
(See  Note  3) to the Partnership's financial statements.  Subsequent
to the filing of the Partnership's Quarterly Report on Form 10-Q, the
Partnership  discovered an omission in the calculation of  the  asset
retirement  liability  and  therefore  has  restated  it's  unaudited
condensed financial statements for the period ended March 31, 2003 as
described in Note 5 to the Partnership's financial statements.

Introductory Note - Depletion Method
During the fourth quarter of 2002, the Partnership changed its method
of  providing for depletion from the units-of-revenue method  to  the
units-of-production  method as described in Notes  4  and  6  to  the
Partnership's financial statements.

This change in depletion method was applied as a cumulative effect of
a  change  in accounting principle effective as of January  1,  2002.
The  unaudited condensed financial statements of the Partnership  for
the  period ended March 31, 2002, included herein, have been restated
(as  described  in  Notes  4  and 6 to  the  Partnership's  financial
statements)  using  the new depletion method and  differ  from  those
previously issued in the Partnership's Quarterly Report on Form  10-Q
for the period ended March 31, 2002.

                      Notes to Financial Statements

1.   Organization
     Southwest  Royalties Institutional Income Fund VII-B,  L.P.  was
     organized under the laws of the state of Delaware on January 28,
     1987,  for  the  purpose  of acquiring  producing  oil  and  gas
     properties  and to produce and market crude oil and natural  gas
     produced  from  such properties for a term of 50  years,  unless
     terminated at an earlier date as provided for in the Partnership
     Agreement.  The Partnership sells its oil and gas production  to
     a  variety  of  purchasers  with the prices  it  receives  being
     dependent  upon  the oil and gas economy.  Southwest  Royalties,
     Inc.  serves as the Managing General Partner and H. H.  Wommack,
     III, as the individual general partner.  Effective December  31,
     2001,  Mr.  Wommack  sold his general partner  interest  to  the
     Managing  General  Partner.  Revenues, costs  and  expenses  are
     allocated as follows:

     The  interim financial information as of March 31, 2003, and for
     the  three  months ended March 31, 2003, is unaudited.   Certain
     information  and  footnote  disclosures  normally  included   in
     financial  statements  prepared  in  accordance  with  generally
     accepted accounting principles have been condensed or omitted in
     this  Form 10-Q/A pursuant to the rules and regulations  of  the
     Securities and Exchange Commission.  However, in the opinion  of
     management, these interim financial statements include  all  the
     necessary  adjustments  to fairly present  the  results  of  the
     interim  periods  and  all  such adjustments  are  of  a  normal
     recurring nature.  The interim consolidated financial statements
     should  be  read  in  conjunction with the Partnership's  Annual
     Report on Form 10-K/A for the year ended December 31, 2002.

3.   Cumulative effect of change in accounting principle - SFAS No.
143
     On  January  1,  2003,  the  Partnership  adopted  Statement  of
     Financial  Accounting  Standards No. 143, Accounting  for  Asset
     Retirement Obligations ("SFAS No. 143").  Adoption of  SFAS  No.
     143  is  required for all companies with fiscal years  beginning
     after  June 15, 2002.  The new standard requires the Partnership
     to  recognize  a liability for the present value  of  all  legal
     obligations  associated with the retirement  of  tangible  long-
     lived assets and to capitalize an equal amount as a cost of  the
     asset  and  depreciate the additional cost  over  the  estimated
     useful  life  of the asset.  On January 1, 2003, the Partnership
     recorded  additional costs, net of accumulated depreciation,  of
     approximately  $38,901, a long term liability  of  approximately
     $66,396  and a loss of approximately $27,495 for the  cumulative
     effect  on  depreciation of the additional costs  and  accretion
     expense  on the liability related to expected abandonment  costs
     of  its oil and natural gas producing properties.  At March  31,
     2003,  the  asset  retirement obligation was  $67,724,  and  the
     increase in the balance from January 1, 2003 of $1,328 is due to
     accretion  expense.  The pro forma amounts for the three  months
     ended  March  31, 2002, which are presented on the face  of  the
     statements  of  operations, reflect the  effect  of  retroactive
     application of SFAS No. 143.

4.    Cumulative effect of change in accounting principle - change in
depletion method
     In  the  fourth quarter of 2002, the Partnership changed methods
     of accounting for depletion of capitalized costs from the units-
     of-revenue method to the units-of-production method.  The  newly
     adopted  accounting principle is preferable in the circumstances
     because  the  units-of-production method  results  in  a  better
     matching  of  the  costs of oil and gas production  against  the
     related  revenue  received in periods  of  volatile  prices  for
     production   as   have  been  experienced  in  recent   periods.
     Additionally, the units-of-production method is the  predominant
     method  used by full cost companies in the oil and gas industry,
     accordingly,  the  change  improves  the  comparability  of  the
     Partnership's  financial statements with its  peer  group.   The
     Partnership  adopted the units-of-production method through  the
     recording  of  a  cumulative effect of a  change  in  accounting
     principle  in the amount of $16,000 effective as of  January  1,
     2002.   The  Partnership's depletion for the three months  ended
     March  31, 2003 and 2002 has been calculated using the units-of-
     production method.  The effect of the change on the three months
     ended  March  31, 2002 was to decrease income before  cumulative
     effect  of a change in accounting principle by $5,000 ($.30  per
     limited  partner unit) and increase net income by $11,000  ($.66
     per limited partner unit).

5.   March 31, 2003 Restatement
     On  January  1,  2003,  the  Partnership  adopted  Statement  of
     Financial Accounting Standards No. 143 as described in Note 3.

     Subsequent to the issuance of the Partnership's Quarterly Report
     on  Form  10-Q  for the three months ended March 31,  2003,  the
     Partnership  determined that it did not  properly  discount  the
     estimated future plugging liability to its present value.

     This  change in the calculation used to determine the amount  of
     the  Partnership's asset retirement liability under SFAS No. 143
     resulted  in a decrease in the Partnership's previously reported
     other long term liability of $85,131 from $152,855 to $67,724 as
     of March 31, 2003 and did not effect the Partnership's 2003 cash
     flows from operations, investing or financing activities.

     The  change  had  the  following effects  on  the  Statement  of
     Operations for the three months ended March 31, 2003.   (Periods
     prior to 2003 were not affected by the change).

6.   March 31, 2002 Restatement
     During  the fourth quarter of 2002, the Partnership changed  its
     method  of  providing  for depletion from  the  units-of-revenue
     method to the units-of-production method as described in Note 4.

     Subsequent to the issuance of the Partnership's Quarterly Report
     on  Form  10-Q  for the three months ended March 31,  2003,  the
     Partnership  determined  that the  above  change  in  accounting
     method  should  have  been  adopted  by  the  Partnership  as  a
     cumulative effect of a change in accounting principle  effective
     as  of  January 1, 2002.  The Partnership had previously applied
     the   change   in   the  method  of  providing   for   depletion
     prospectively as of October 1, 2002.

     This  change  in the method used to implement the  Partnership's
     change  in the manner in which it determines depletion  resulted
     in  an increase in the Partnership's previously reported net oil
     and  gas properties of $11,000 from $649,965 to $660,965  as  of
     December 31, 2002 and did not effect the Partnership's 2002 cash
     flows from operations, investing or financing activities.

     The  change  had  the  following effects  on  the  Statement  of
     Operations for the three months ended March 31, 2002.

Item 2.   Management's Discussion and Analysis of Financial Condition
          and Results of Operations

General

Southwest  Royalties  Institutional  Income  Fund  VII-B,  L.P.   was
organized as a Delaware limited partnership on January 28, 1987.  The
offering  of such limited partnership interests began March 23,  1987
minimum  capital  requirements were met May 20,  1987  and  concluded
December  1,  1987,  with  total  limited  partner  contributions  of
$7,500,000.

The  Partnership  was  formed  to acquire  royalty  and  net  profits
interests in producing oil and gas properties, to produce and  market
crude  oil  and  natural gas produced from such  properties,  and  to
distribute  the  net  proceeds from operations  to  the  limited  and
general partners.  Net revenues from producing oil and gas properties
will  not  be reinvested in other revenue producing assets except  to
the  extent  that  production facilities and wells  are  improved  or
reworked  or  where methods are employed to improve  or  enable  more
efficient recovery of oil and gas reserves. The economic life of  the
Partnership  thus depends on the period over which the  Partnership's
oil and gas reserves are economically recoverable.

Increases  or  decreases  in  Partnership  revenues  and,  therefore,
distributions  to partners will depend primarily on  changes  in  the
prices  received  for  production, changes in volumes  of  production
sold,  lease  operating expenses, enhanced recovery projects,  offset
drilling  activities  pursuant  to farm-out  arrangements,  sales  of
properties,  and  the depletion of wells.  Since wells  deplete  over
time,  production can generally be expected to decline from  year  to
year.

Well  operating  costs and general and administrative  costs  usually
decrease  with  production declines; however,  these  costs  may  not
decrease  proportionately.  Net income available for distribution  to
the  partners is therefore expected to fluctuate in later years based
on these factors.

Based   on  current  conditions,  management  anticipates  performing
development drilling projects and workovers during the years 2003 and
2004 to enhance production.  The partnership may have an increase  in
production  volumes  for  the years 2003  and  2004,  otherwise,  the
partnership  will  most  likely experience the historical  production
decline, which has approximated 15% per year.

Oil and Gas Properties

Oil  and gas properties are accounted for at cost under the full-cost
method.   Under  this method, all productive and nonproductive  costs
incurred   in  connection  with  the  acquisition,  exploration   and
development of oil and gas reserves are capitalized.  Gain or loss on
the  sale  of  oil  and  gas  properties  is  not  recognized  unless
significant oil and gas reserves are involved.

In  the  fourth quarter of 2002, the Partnership changed  methods  of
accounting  for  depletion of capitalized costs  from  the  units-of-
revenue  method to the units-of-production method.  The newly adopted
accounting  principle is preferable in the circumstances because  the
units-of-production method results in a better matching of the  costs
of  oil  and  gas production against the related revenue received  in
periods of volatile prices for production as have been experienced in
recent periods.  Additionally, the units-of-production method is  the
predominant  method used by full cost companies in the  oil  and  gas
industry, accordingly, the change improves the comparability  of  the
Partnership's financial statements with its peer group.   The  effect
of  this  change in method was to increase depletion expense for  the
three  months ended March 31, 2002 by $5,000 and increase net  income
for the three months ended March 31, 2002 by $11,000.  See Note 4  of
the notes to the Partnership's financial statements.

Should  the net capitalized costs exceed the estimated present  value
of  oil and gas reserves, discounted at 10%, such excess costs  would
be  charged  to  current  expense. As of  March  31,  2003,  the  net
capitalized costs did not exceed the estimated present value  of  oil
and gas reserves.


The  Partnership's interest in oil and gas properties consists of net
profits interests in proved properties located within the continental
United States.  A net profits interest is created when the owner of a
working  interest in a property enters into an arrangement  providing
that  the net profits interest owner will receive a stated percentage
of  the net profit from the property.  The net profits interest owner
will  not  otherwise participate in additional costs and expenses  of
the property.

The  Partnership recognizes income from its net profits  interest  in
oil  and  gas property on an accrual basis, while the quarterly  cash
distributions of the net profits interest are based on a  calculation
of  actual  cash  received from oil and gas sales,  net  of  expenses
incurred  during  that quarterly period. If the net profits  interest
calculation  results in expenses incurred exceeding the oil  and  gas
income received during a quarter, no cash distribution is due to  the
Partnership's  net  profits interest until the deficit  is  recovered
from future net profits.  The Partnership accrues a quarterly loss on
its  net  profits interest provided there is a cumulative net  amount
due  for  accrued revenue as of the balance sheet date.  As of  March
31,  2003,  there  were no timing differences, which  resulted  in  a
deficit net profit interest.

Critical Accounting Policies

Full  cost ceiling calculations The Partnership follows the full cost
method  of accounting for its oil and gas properties.  The full  cost
method  subjects companies to quarterly calculations of a  "ceiling",
or  limitation on the amount of properties that can be capitalized on
the  balance  sheet.  If the Partnership's capitalized costs  are  in
excess  of the calculated ceiling, the excess must be written off  as
an expense.

The  Partnership's  discounted present value of its  proved  oil  and
natural gas reserves is a major component of the ceiling calculation,
and  represents  the  component  that requires  the  most  subjective
judgments.   Estimates of reserves are forecasts based on engineering
data,  projected future rates of production and the timing of  future
expenditures.  The process of estimating oil and natural gas reserves
requires substantial judgment, resulting in imprecise determinations,
particularly  for new discoveries.  Different reserve  engineers  may
make  different  estimates of reserve quantities based  on  the  same
data.   The  Partnership's reserve estimates are on an  annual  basis
prepared  by  outside consultants.  Quarterly reserve  estimates  are
prepared  by  the  Managing  General  Partner's  internal  staff   of
engineers.

The  passage of time provides more qualitative information  regarding
estimates  of reserves, and revisions are made to prior estimates  to
reflect updated information.  However, there can be no assurance that
more  significant revisions will not be necessary in the future.   If
future  significant  revisions are necessary that  reduce  previously
estimated reserve quantities, it could result in a full cost property
writedown.   In addition to the impact of these estimates  of  proved
reserves  on calculation of the ceiling, estimates of proved reserves
are also a significant component of the calculation of DD&A.

While the quantities of proved reserves require substantial judgment,
the  associated  prices  of oil and natural  gas  reserves  that  are
included  in  the  discounted present value of the  reserves  do  not
require  judgment.  The ceiling calculation dictates that prices  and
costs  in effect as of the last day of the period are generally  held
constant indefinitely. Because the ceiling calculation dictates  that
prices  in  effect as of the last day of the applicable  quarter  are
held constant indefinitely, the resulting value is not indicative  of
the true fair value of the reserves.  Oil and natural gas prices have
historically been cyclical and, on any particular day at the end of a
quarter,  can  be  either  substantially higher  or  lower  than  the
Partnership's long-term price forecast that is a barometer  for  true
fair value.

In  the  fourth quarter of 2002, the Partnership changed  methods  of
accounting  for  depletion of capitalized costs  from  the  units-of-
revenue  method to the units-of-production method.  The newly adopted
accounting  principle is preferable in the circumstances because  the
units-of-production method results in a better matching of the  costs
of  oil  and  gas production against the related revenue received  in
periods of volatile prices for production as have been experienced in
recent periods.  Additionally, the units-of-production method is  the
predominant  method used by full cost companies in the  oil  and  gas
industry, accordingly, the change improves the comparability  of  the
Partnership's financial statements with its peer group.   The  effect
of  this  change in method was to increase depletion expense for  the
three  months ended March 31, 2002 by $5,000 and increase net  income
for the three months ended March 31, 2002 by $11,000.

Revenues

The  Partnership's  income from net profits  interests  increased  to
$262,934  from  $137,418 for the quarters ended March  31,  2003  and
2002,  respectively,  an  increase of  91%.   The  principal  factors
affecting  the comparison of the quarters ended March  31,  2003  and
2002 are as follows:

1.  The average price for a barrel of oil received by the Partnership
    increased during the quarter ended March 31, 2003 as compared  to
    the  quarter  ended March 31, 2002 by 62%, or $12.18 per  barrel,
    resulting in an increase of approximately $73,100 in income  from
    net  profits interests.  Oil sales represented 57% of  total  oil
    and  gas  sales during the quarter ended March 31, 2003  and  76%
    during the quarter ended March 31, 2002.

    The  average  price for an mcf of gas received by the Partnership
    increased  during  the same period by 205%,  or  $4.07  per  mcf,
    resulting in an increase of approximately $96,500 in income  from
    net profits interests.

    The  total increase in income from net profits interests  due  to
    the  change  in  prices received from oil and gas  production  is
    approximately $169,600. The market price for oil and gas has been
    extremely volatile over the past decade, and management expects a
    certain  amount  of  volatility to continue  in  the  foreseeable
    future.


2.  Oil  production  decreased approximately  1,400  barrels  or  19%
    during  the  quarter  ended March 31, 2003  as  compared  to  the
    quarter  ended  March  31,  2002,  resulting  in  a  decrease  of
    approximately $27,400 in revenues.

    Gas  production increased approximately 900 mcf or 4% during  the
    same period, resulting in an increase of approximately $1,800  in
    income from net profits interests.

    The  total net decrease in income from net profits interests  due
    to  the  change  in  production is  approximately  $25,600.   The
    decrease  in  oil  production  is due  to  a  non-operated  lease
    experiencing a sharp natural decline.

3.  Lease  operating costs and production taxes were 35%  higher,  or
    approximately  $18,400 more during the quarter  ended  March  31,
    2003  as  compared  to  the quarter ended March  31,  2002.   The
    increase in lease operating expense and production taxes  is  due
    to several wells having repairs and maintenance performed, and an
    increase in production taxes due to an increase in gross revenues
    received during the three months ended March 31, 2003.

Costs and Expenses

Total  costs and expenses increased to $47,998 from $45,644  for  the
quarters ended March 31, 2003 and 2002, respectively, an increase  of
5%.   The  increase  is  a  direct result of  the  accretion  expense
associated   with  our  long  term  liability  related  to   expected
abandonment  costs  of our oil and natural gas properties,  depletion
expense and general and administrative expense.

1.  General   and   administrative  costs  consists  of   independent
    accounting and engineering fees, computer services, postage,  and
    Managing   General   Partner  personnel   costs.    General   and
    administrative costs increased less than 1% or approximately  $30
    during  the  quarter  ended March 31, 2003  as  compared  to  the
    quarter ended March 31, 2002.

2.  Depletion  expense  increased to $18,000 for  the  quarter  ended
    March  31,  2003 from $17,000 for the same period in 2002.   This
    represents an increase of 6%.  In the fourth quarter of 2002, the
    Partnership  changed  methods  of  accounting  for  depletion  of
    capitalized costs from the units-of-revenue method to the  units-
    of-production method.  The newly adopted accounting principle  is
    preferable  in  the circumstances because the units-of-production
    method  results in a better matching of the costs of oil and  gas
    production  against the related revenue received  in  periods  of
    volatile prices for production as have been experienced in recent
    periods.   Additionally, the units-of-production  method  is  the
    predominant method used by full cost companies in the oil and gas
    industry,  accordingly, the change improves the comparability  of
    the  Partnership's financial statements with its peer group.  The
    effect of this change in method was to increase depletion expense
    for  the three months ended March 31, 2002 by $5,000 and increase
    net income for the three months ended March 31, 2002 by $11,000.

Cumulative effect of change in accounting principle

On  January  1, 2003, the Partnership adopted Statement of  Financial
Accounting   Standards  No.  143,  Accounting  for  Asset  Retirement
Obligations  ("SFAS No. 143").  Adoption of SFAS No. 143 is  required
for  all  companies with fiscal years beginning after June 15,  2002.
The  new  standard requires the Partnership to recognize a  liability
for  the  present value of all legal obligations associated with  the
retirement of tangible long-lived assets and to capitalize  an  equal
amount as a cost of the asset and depreciate the additional cost over
the  estimated  useful life of the asset.  On January  1,  2003,  the
Partnership   recorded   additional   costs,   net   of   accumulated
depreciation,  of  approximately $38,901, a long  term  liability  of
approximately  $66,396 and a loss of approximately  $27,495  for  the
cumulative  effect  on  depreciation  of  the  additional  costs  and
accretion  expense  on the liability related to expected  abandonment
costs of its oil and natural gas producing properties.  At March  31,
2003,  the asset retirement obligation was $67,724, and the  increase
in  the  balance from January 1, 2003 of $1,328 is due  to  accretion
expense.  The pro forma amounts for the three months ended March  31,
2002,  which  are  presented  on  the  face  of  the  statements   of
operations, reflect the effect of retroactive application of SFAS No.
143.


Liquidity and Capital Resources

The  primary source of cash is from operations, the receipt of income
from  interests in oil and gas properties.  The Partnership knows  of
no material change, nor does it anticipate any such change.

Cash  flows  provided  by  operating  activities  were  approximately
$179,100  in  the  quarter  ended  March  31,  2003  as  compared  to
approximately  $81,900  in the quarter ended  March  31,  2002.   The
primary  source  of the 2003 cash flow from operating activities  was
profitable operations.

Cash  flows used in financing activities were approximately  $150,400
in  the  quarter  ended March 31, 2003 as compared  to  approximately
$149,300  in  the  quarter ended March 31, 2002.   The  only  use  in
financing activities was the distributions to partners.

Total  distributions  during the quarter ended March  31,  2003  were
$150,000  of  which $135,000 was distributed to the limited  partners
and  $15,000  to  the general partner.  The per unit distribution  to
limited  partners during the quarter ended March 31, 2003 was  $9.00.
Total  distributions  during the quarter ended March  31,  2002  were
$150,000  of  which $135,000 was distributed to the limited  partners
and  $15,000  to the general partners.  The per unit distribution  to
limited partners during the quarter ended March 31, 2002 was $9.00.

The  source  for the 2003 distributions of $150,000 was oil  and  gas
operations  of approximately $179,100, resulting in excess  cash  for
contingencies or subsequent distributions.  The source for  the  2002
distributions of $150,000 was oil and gas operations of approximately
$81,900,  with  the  balance  from available  cash  on  hand  at  the
beginning of the period.

Since   inception  of  the  Partnership,  cumulative   monthly   cash
distributions of $11,516,053 have been made to the partners.   As  of
March  31, 2003, $10,379,358 or $691.96 per limited partner unit  has
been  distributed to the limited partners, representing a 100% return
of the capital and a 38% return on capital contributed.

As  of March 31, 2003, the Partnership had approximately $291,700  in
working  capital.  The Managing General Partner knows of  no  unusual
contractual  commitments.  Although the partnership held  many  long-
lived  properties  at  inception,  because  of  the  restrictions  on
property  development  imposed  by  the  partnership  agreement,  the
Partnership  cannot  develop its non producing  properties,  if  any.
Without  continued  development, the producing reserves  continue  to
deplete.   Accordingly, as the Partnership's properties have  matured
and  depleted, the net cash flows from operations for the partnership
has  steadily declined, except in periods of substantially  increased
commodity  pricing.   Maintenance of  properties  and  administrative
expenses  for the Partnership are increasing relative to  production.
As  the properties continue to deplete, maintenance of properties and
administrative  costs as a percentage of production are  expected  to
continue to increase.

The  Managing  General Partner has examined various  alternatives  to
address  the  issue  of  depleting  producing  reserves.   Continuing
operations  exposes  the  partnership to  an  inevitable  decline  in
operating  results  and  distributions  of  cash.   Liquidating   the
partnership would result in immediate realization of cash for limited
partners,  but prices paid by purchasers of Partnership  property  in
liquidation would likely include a substantial discount for risks and
uncertainties of future cash flows, as well as any development risks.
After  reviewing various alternatives, we initiated a plan  to  merge
the  Partnership and 20 other limited partnerships with and into  the
Managing General Partner.  On October 17, 2002, the Managing  General
Partner  filed  a  Registration  Statement  on  form  S-4  with   the
Securities and Exchange Commission relating to this proposed  merger.
There is no assurance, however, that this merger will be consummated.


Liquidity - Managing General Partner

The Managing General Partner has a highly leveraged capital structure
with  approximately $124.0 million of principal due between  December
31,  2002  and  December 31, 2004.  The Managing General  Partner  is
constantly monitoring its cash position and its ability to  meet  its
financial  obligations as they become due, and  in  this  effort,  is
continually  exploring various strategies for addressing its  current
and  future liquidity needs.  The Managing General Partner  regularly
pursues  and  evaluates recapitalization strategies  and  acquisition
opportunities   (including  opportunities  to  engage   in   mergers,
consolidations or other business combinations) and at any given  time
may be in various stages of evaluating such opportunities.

Based  on  current production, commodity prices and  cash  flow  from
operations,  the Managing General Partner has adequate cash  flow  to
fund  debt service, developmental projects and day to day operations,
but  it  is not sufficient to build a cash balance which would  allow
the  Managing  General Partner to meet its debt principal  maturities
scheduled  for  2004.   Therefore the  Managing  General  Partner  is
currently  seeking  to  renegotiate the  terms  of  its  obligations,
including  extending  maturity dates, or to  engage  new  lenders  or
equity  investors  in  order  to satisfy  its  financial  obligations
maturing in 2004.

There  can  be no assurance that the Managing General Partner's  debt
restructuring efforts will be successful.  In the event these efforts
are unsuccessful, the Managing General Partner would need to look  to
other   alternatives   to   meet  its  debt  obligations,   including
potentially selling its assets.  There can be no assurance,  however,
that  the  sales of assets can be successfully accomplished on  terms
acceptable  to  the  Managing  General  Partner.   Please   see   the
Partnership's Quarterly Report on Form 10-Q for the quarterly  period
ended September 30, 2003, which will be filed with the Commission  on
or before November 14, 2003, for updated information on the liquidity
of  the  Managing  General Partner.  The liquidity  of  the  Managing
General  Partner,  however, does not have a material  impact  on  the
operations  of  the Partnership.  The partnership  agreement  of  the
Partnership allows the limited partners to elect a successor managing
general partner to continue Partnership operations.

Recent Accounting Pronouncements

The   FASB  has  issued  Statement  No.  143  "Accounting  for  Asset
Retirement  Obligations"  which  establishes  requirements  for   the
accounting  of removal-type costs associated with asset  retirements.
The  standard is effective for fiscal years beginning after June  15,
2002,  with earlier application encouraged.  This statement has  been
adopted by the Partnership effective January 1, 2003.  The transition
adjustment  resulting  from the adoption of SFAS  No.  143  has  been
reported as a cumulative effect of a change in accounting principle.

In  April  2003,  the  FASB issued Statement of Financial  Accounting
Standards  No.  149,  Amendment of Statement No.  133  on  Derivative
Instruments  and Hedging Activities ("SFAS No. 149").  SFAS  No.  149
amendments require that contracts with comparable characteristics  be
accounted  for similarly, clarifies when a contract with  an  initial
investment  meets  the characteristic of a derivative  and  clarifies
when a derivative requires special reporting in the statement of cash
flows.    SFAS   No.  149  is  effective  for  hedging  relationships
designated and for contracts entered into or modified after June  30,
2003,  except  for provisions that relate to SFAS No.  133  Statement
Implementation  Issues that have been effective for  fiscal  quarters
prior  to  June 15, 2003, should be applied in accordance with  their
respective effective dates and certain provisions relating to forward
purchases or sales of when-issued securities or other securities that
do  not yet exist, should be applied to existing contracts as well as
new  contracts entered into after June 30, 2003.  Assessment  by  the
Managing  General  Partner  revealed this pronouncement  to  have  no
impact on the partnership.



Item 3.   Quantitative and Qualitative Disclosures About Market Risk

The  Partnership  is  not  a  party to  any  derivative  or  embedded
derivative instruments.

Item 4.   Controls and Procedures

(a)  Evaluation  of  Disclosure Controls and Procedures.   The  chief
executive  officer  and chief financial officer of the  Partnership's
managing  general  partner have evaluated the  effectiveness  of  the
design  and  operation of the Partnership's disclosure  controls  and
procedures (as defined in Exchange Act Rule 13a-14(c)) as of  a  date
within 90 days of the filing date of this quarterly report. Based  on
that  evaluation,  the chief executive officer  and  chief  financial
officer have concluded that the Partnership's disclosure controls and
procedures are effective to ensure that material information relating
to the Partnership and the Partnership's consolidated subsidiaries is
made  known  to  such  officers  by  others  within  these  entities,
particularly during the period this quarterly report was prepared, in
order to allow timely decisions regarding required disclosure.

(b)   Changes  in  Internal  Controls.   There  have  not  been   any
significant  changes  in the Partnership's internal  controls  or  in
other   factors  that  could  significantly  affect  these   controls
subsequent to the date of their evaluation.
