                     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 IX-B, L.P. was organized
     under  the  laws of the state of Delaware on March 9,  1989,  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.  Revenues, costs  and  expenses  are
     allocated as follows:

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 $151,827, a long  term  liability  of
     approximately  $163,672 and a loss of approximately  $11,845  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 $166,946, and the  increase
     in  the  balance  from January 1, 2003 of $3,273 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  $31,000 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 $2,000 ($.20 per limited partner unit) and net income  by
     $33,000 ($3.37 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 $209,370 from $376,316 to $166,946 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 a decrease
     in the Partnership's previously reported net oil and gas properties of
     $32,000 from $264,222 to $232,222 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 IX-B, L.P. was organized as a
Delaware limited partnership on March 9, 1989. The offering of such limited
partnership  interests began on May 11, 1989, minimum capital  requirements
were  met  on September 26, 1989, and the offering concluded on  March  31,
1990, with total limited partner contributions of $4,891,000.

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 are not 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  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 8% 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 $2,000  and
decrease  net income for the three months ended March 31, 2002 by  $33,000.
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 $2,000  and
decrease net income for the three months ended March 31, 2002 by $33,000.

The  Partnership's income from net profits interests increased to  $167,555
from  $56,905 for the quarters ended March 31, 2003 and 2002, respectively,
an increase of 194%.  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 68%, or $13.15 per barrel, resulting in
    an  increase  of  approximately $55,200  in  income  from  net  profits
    interests.  Oil sales represented 55% of total oil and gas sales during
    the  quarter ended March 31, 2003 as compared to 67% 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 202%, or $3.49 per mcf,  resulting
    in  an  increase  of approximately $73,600 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
    $128,800.  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 500 barrels or 11%  during  the
    same  period, resulting in a decrease of approximately $9,700 in income
    from net profits interests.

    Gas production decreased approximately 4,700 mcf or 18% during the same
    period, resulting in a decrease of approximately $8,100 in income  from
    net profits interests.

    The  total  decrease in income from net profits interests  due  to  the
    change  in  production is approximately $17,800.  The decrease  in  gas
    production  is  primarily due to a property sale during November  2002,
    which  produced approximately 4,500 mcf during the quarter ended  March
    31, 2002.

3.  Lease  operating  costs  and  production  taxes  were  1%  higher,   or
    approximately  $400 more during the quarter ended  March  31,  2003  as
    compared to the quarter ended March 31, 2002.

Costs and Expenses

Total costs and expenses increased to $27,798 from $24,400 for the quarters
ended  March  31,  2003 and 2002, respectively, an increase  of  14%.   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 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 1%
    or  approximately  $100  during the quarter ended  March  31,  2003  as
    compared to the quarter ended March 31, 2002.

2.  Depletion  expense remained unchanged for the quarter ended  March  31,
    2003 as compared to the same period in 2002.  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
    $2,000  and  decrease net income for the three months ended  March  31,
    2002 by $33,000.

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  $151,827,  a  long  term   liability   of
approximately  $163,672  and  a  loss  of  approximately  $11,845  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 $166,946, and the increase in the  balance  from
January  1,  2003  of $3,273 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 $99,300  in
the  quarter ended March 31, 2003 as compared to approximately  $42,800  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 $80,100 in  the
quarter  ended March 31, 2003 as compared to approximately $50,100  in  the
quarter ended March 31, 2003.  The only use in financing activities was the
distributions to partners.

Total distributions during the quarter ended March 31, 2003 were $80,000 of
which  $72,000  was distributed to the limited partners and $8,000  to  the
general partners.  The per unit distribution to limited partners during the
quarter  ended  March 31, 2003 was $7.36.  Total distributions  during  the
quarter  ended March 31, 2002 were $50,000 of which $45,000 was distributed
to  the limited partners and $5,000 to the general partners.  The per  unit
distribution  to limited partners during the quarter ended March  31,  2002
was $4.60.

The source for the 2003 distributions of $80,000 was oil and gas operations
of  approximately  $99,300, resulting in excess cash for  contingencies  or
subsequent distributions.  The source for the 2002 distributions of $50,000
was  oil and gas operations of approximately $42,800, with the balance from
available cash on hand at the beginning of the period.

Since  inception of the Partnership, cumulative monthly cash  distributions
of  $7,205,286  have  been made to the partners.  As  of  March  31,  2003,
$6,540,018 or $668.58 per limited partner unit has been distributed to  the
limited partners, representing a 100% return of the capital and 34%  return
on capital contributed.

As of March 31, 2003, the Partnership had approximately $204,300 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.  The Managing General Partner is currently assessing the impact
on  the partnerships financial statements.  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.
