                      Notes to Financial Statements

1.  Organization
          Southwest Royalties, Inc. Income Fund VI was organized under  the
    laws of the state of Tennessee on December 4, 1986, 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.  a
    wholly-owned subsidiary of Clayton Williams Energy, Inc., serves as the
    Managing  General Partner.  Revenues, costs and expenses are  allocated
    as follows:

         will  be treated as a capital contribution.  The Partnership  paid
         the  Managing  General Partner an amount equal to  3%  of  initial
         capital contributions for such organization costs.

         (2)Administrative  costs in any year which exceed  2%  of  capital
         contributions  shall be paid by the Managing General  Partner  and
         will be treated as a capital contribution.

2.   Summary of Significant Accounting Policies
     The  interim  financial information as of June 30, 2004, and  for  the
     three  and  six  months  ended June 30, 2004, 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  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 for the year ended December 31, 2003.

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 $616,464, a long  term  liability  of
     approximately  $499,827 and a gain of approximately $116,637  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 June  30,
     2004,  the asset retirement obligation was $533,936.  The increase  in
     the  asset  retirement  obligation from January  1,  2004  is  due  to
     accretion expense of $20,535.

4.   Change in Control of Managing General Partner
     On  May  21,  2004,  Clayton Williams Energy, Inc.  acquired  all  the
     outstanding common stock of Southwest Royalties Inc. through a merger.
     Clayton  Williams  Energy,  Inc. paid  $57.1  million  to  holders  of
     Southwest  Royalties,  Inc.  common stock and  common  stock  warrants
     ($45.01   per   share)   and  assumed  and  refinanced   approximately
     $113.9 million of assumed bank debt at closing.

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

General

Southwest  Royalties,  Inc. Income Fund VI was  organized  as  a  Tennessee
limited  partnership  on  December 4, 1986. The offering  of  such  limited
partnership  interests began August 25, 1986 minimum  capital  requirements
were met October 3, 1986 and concluded January 29, 1987, with total limited
partner contributions of $10,000,000.

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.

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
sold.

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 June 30, 2004, the net capitalized costs  did  not
exceed the estimated present value of oil and gas reserves.

<PAGE>
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
June  30,  2004,  there were no timing differences,  which  resulted  in  a
deficit net profit interest.

Critical Accounting Policies

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 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.

Revenues

The  Partnership's income from net profits interests decreased to  $314,554
from  $331,408 for the quarters ended June 30, 2004 and 2003, respectively,
a  decrease of 5%.  The principal factors affecting the comparison  of  the
quarters ended June 30, 2004 and 2003 are as follows:

1.  The  average  price  for a barrel of oil received  by  the  Partnership
    increased  during the quarter ended June 30, 2004 as  compared  to  the
    quarter  ended June 30, 2003 by 31%, or $8.76 per barrel, resulting  in
    an  increase  of  approximately $42,700  in  income  from  net  profits
    interests.  Oil sales represented 32% of total oil and gas sales during
    the  quarter ended June 30, 2004 as compared to 33% during the  quarter
    ended June 30, 2003.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    increased during the same period by 17%, or $.84 per mcf, resulting  in
    an  increase  of  approximately $56,600  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
    $99,300.   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.

<PAGE>
2.  Oil  production decreased approximately 1,530 barrels or 24% during the
    quarter  ended June 30, 2004 as compared to the quarter ended June  30,
    2003,  resulting in a decrease of approximately $43,600 in income  from
    net profits interests.

    Gas production decreased approximately 7,475 mcf or 10% during the same
    period, resulting in a decrease of approximately $36,900 in income from
    net profits interests.

    The  total  decrease in income from net profits interests  due  to  the
    change  in  production is approximately $80,500.  Oil and  gas  volumes
    were  down due to the sale of two producing properties in 2003.   Steep
    production declines contributed to the decline in oil volumes.

3.  Lease  operating  costs  and  production  taxes  were  16%  higher,  or
    approximately $35,500 more during the quarter ended June  30,  2004  as
    compared  to  the quarter ended June 30, 2003.  The increase  in  lease
    operating  costs is the result of adding artificial lift  equipment  to
    one well and the recompletion of another well.

Costs and Expenses

Total costs and expenses decreased to $82,870 from $97,421 for the quarters
ended  June  30,  2004  and 2003, respectively, a  decrease  of  15%.   The
decrease  is  the  result of lower general and administrative  expense  and
depletion expense, partially offset by an increase in accretion expense.

1.  General  and  administrative costs consists of independent  accounting,
    legal  and  engineering fees, computer services, postage, and  Managing
    General  Partner  personnel costs.  General  and  administrative  costs
    decreased 12% or approximately $5,800 during the quarter ended June 30,
    2004  as  compared  to  the quarter ended June 30,  2003.   The  higher
    general  and  administrative expense in  2003  is  due  to  legal  fees
    associated with the amendments to the Partnership's December  31,  2002
    Annual Report on Form 10-K and March 31, 2003 Quarterly Report on  Form
    10-Q.

2.  Depletion expense decreased to $29,000 for the quarter ended  June  30,
    2004  from  $38,000  for the same period in 2003.   This  represents  a
    decrease  of 24%.  The contributing factor to the decrease in depletion
    expense is in relation to the BOE depletion rate for the quarter  ended
    June  30,  2004, which was $1.80 applied to 16,091 BOE as  compared  to
    $2.01 applied to 18,867 BOE for the same period in 2003.

3.  Accretion expense increased to $10,268 for the quarter ended  June  30,
    2004  from  $9,997  for the same period in 2003.   This  represents  an
    increase of 3%.

Revenues

The  Partnership's income from net profits interests increased to  $695,779
from   $628,687  for  the  six  months  ended  June  30,  2004  and   2003,
respectively,  an  increase of 11%.  The principal  factors  affecting  the
comparison of the six months ended June 30, 2004 and 2003 are as follows:

1.  The  average  price  for a barrel of oil received  by  the  Partnership
    increased during the six months ended June 30, 2004 as compared to  the
    six  months ended June 30, 2003 by 16%, or $4.90 per barrel,  resulting
    in  an  increase  of approximately $52,700 in income from  net  profits
    interests.  Oil sales represented 34% of total oil and gas sales during
    the  six  months ended June 30, 2004 as compared to 32% during the  six
    months ended June 30, 2003.

    The  average  price  for  a  mcf  of gas received  by  the  Partnership
    increased  during the same period by 6%, or $.34 per mcf, resulting  in
    an  increase  of  approximately $42,900  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
    $95,600.   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 250 barrels or 2% during the six
    months ended June 30, 2004 as compared to the six months ended June 30,
    2003,  resulting in a decrease of approximately $7,500 in  income  from
    net profits interests.

    Gas  production decreased approximately 3,475 mcf or 3% during the same
    period, resulting in a decrease of approximately $18,700 in income from
    net profits interests.

    The  total  decrease in income from net profits interests  due  to  the
    change in production is approximately $26,200.

3.  Lease  operating  costs  and  production  taxes  were  1%  higher,   or
    approximately $2,100 more during the six months ended June 30, 2004  as
    compared to the six months ended June 30, 2003.

Costs and Expenses

Total  costs and expenses decreased to $160,421 from $172,893 for  the  six
months  ended June 30, 2004 and 2003, respectively, a decrease of 7%.   The
decrease  is  the  result  of a lower depletion  expense  and  general  and
administrative  expense,  partially offset  by  an  increase  in  accretion
expense.

1.  General  and  administrative costs consists of independent  accounting,
    legal  and  engineering fees, computer services, postage, and  Managing
    General  Partner  personnel costs.  General  and  administrative  costs
    decreased  3% or approximately $3,000 during the six months ended  June
    30, 2004 as compared to the six months ended June 30, 2003.  The higher
    general  and  administrative expense in  2003  is  due  to  legal  fees
    associated with the amendments to the Partnership's December  31,  2002
    Annual Report on Form 10-K and March 31, 2003 Quarterly Report on  Form
    10-Q.

2.  Depletion  expense decreased to $56,000 for the six months  ended  June
    30,  2004 from $66,000 for the same period in 2003.  This represents  a
    decrease  of 15%.  The contributing factor to the decrease in depletion
    expense  is  in relation to the BOE depletion rate for the  six  months
    ended  June 30, 2004, which was $1.76 applied to 31,771 BOE as compared
    to $2.02 applied to 32,600 BOE for the same period in 2003.

3.  Accretion  expense increased to $20,535 for the six months  ended  June
    30, 2004 from $19,993 for the same period in 2003.  This represents  an
    increase of 3%.

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 $511,842  in
the six months ended June 30, 2004 as compared to approximately $367,500 in
the six months ended June 30, 2003.

There were no cash flows provided by investing activities in the six months
ended  June  30,  2004.  Cash flows provided by investing  activities  were
approximately $300 in the six months ended June 30, 2003.

Cash flows used in financing activities were approximately $575,000 in  the
six months ended June 30, 2004 as compared to approximately $253,600 in the
six  months ended June 30, 2003.  The only use in financing activities  was
the distributions to partners.

Total distributions during the six months ended June 30, 2004 were $575,000
of  which  $517,500 was distributed to the limited partners and $57,500  to
the  general partner. The per unit distribution to limited partners  during
the  six months ended June 30, 2004 was $25.88.  Total distributions during
the  six  months  ended June 30, 2003 were $250,000 of which  $225,000  was
distributed to the limited partners and $25,000 to the general partner. The
per  unit distribution to limited partners during the six months ended June
30, 2003 was $11.25.

The  sources  for  the  2004 distributions of $575,000  were  oil  and  gas
operations of approximately $511,800, with the balance from available  cash
on  hand  at  the  beginning  of  the period.  The  sources  for  the  2003
distributions  of  $250,000  were oil and gas operations  of  approximately
$367,500  and  the change in oil and gas properties of approximately  $300,
resulting in excess cash for contingencies or subsequent distributions.

Cumulative cash distributions of $18,778,945 have been made to the  general
and  limited  partners.  As of June 30, 2004, $16,916,759  or  $845.84  per
limited  partner  unit  has  been  distributed  to  the  limited  partners,
representing  a  100%  return of the capital and a 69%  return  on  capital
contributed.

As  of June 30, 2004, the Partnership had approximately $462,600 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.

Managing General Partner

On May 21, 2004, Clayton Williams Energy, Inc. acquired all the outstanding
common stock of Southwest Royalties Inc. through a merger.  Clayton
Williams Energy, Inc. paid $57.1 million to holders of Southwest Royalties,
Inc. common stock and common stock warrants ($45.01 per share) and assumed
and refinanced approximately $113.9 million of assumed bank debt at
closing.

Recent Accounting Pronouncements

The  EITF is considering two issues related to the reporting of oil and gas
mineral  rights.  Issue No. 03-O, "Whether Mineral Rights Are  Tangible  or
Intangible Assets," is whether or not mineral rights are intangible  assets
pursuant  to  SFAS  No.  141,  "Business  Combinations."  Issue  No.  03-S,
"Application of SFAS No. 142, Goodwill and Other Intangible Assets, to  Oil
and  Gas  Companies,"  is, if oil and gas drilling  rights  are  intangible
assets,  whether  those  assets  are  subject  to  the  classification  and
disclosure provisions of SFAS No. 142.  The Partnership classifies the cost
of oil and gas mineral rights as properties and equipment and believes that
this is consistent with oil and gas accounting and industry practice.   The
staff  of the FASB has issued a proposed position clarifying that SFAS  No.
142  does not supersede the balance sheet classification and disclosure for
drilling  and mineral rights of oil and gas producing entities  within  the
scope  of FASB No. 19.   If SFAS No. 142 is determined to apply to oil  and
gas   companies,   the  Partnership  may  be  required  to   make   certain
reclassifications within property and equipment on the balance  sheet,  and
additional  disclosures may be required.  There would be no effect  on  the
statement of income or cash flows as the intangible assets related  to  oil
and  gas mineral rights would continue to be amortized under the full  cost
method of accounting.

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

Disclosure Controls and Procedures
As  of  the  six months ended June 30, 2004, L. Paul Latham, President  and
Chief  Executive Officer of the Managing General Partner, and Mel G. Riggs,
Vice President and Chief Financial Officer of the Managing General Partner,
evaluated  the effectiveness of the Partnership's disclosure  controls  and
procedures.  Based on their evaluation, they believe that:

     The  disclosure  controls  and  procedures  of  the  Partnership  were
     effective in ensuring that information required to be disclosed by the
     Partnership in the reports it files or submits under the Exchange  Act
     was  recorded,  processed,  summarized and reported  within  the  time
     periods specified in the SEC's rules and forms; and

     The  disclosure  controls  and  procedures  of  the  Partnership  were
     effective  in  ensuring  that  material  information  required  to  be
     disclosed by the Partnership in the report it filed or submitted under
     the  Exchange  Act was accumulated and communicated  to  the  Managing
     General  Partner's  management, including its Chief Executive  Officer
     and  Chief Financial Officer, as appropriate to allow timely decisions
     regarding required disclosure.

Internal Control Over Financial Reporting
There  has  not been any change in the Partnership's internal control  over
financial reporting that occurred during the six months ended June 30, 2004
that has materially affected, or is reasonably likely to materially affect,
internal control over financial reporting.
