                      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:

         contributions  will  be paid by the Managing General  Partner  and
         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

2.   Summary of Significant Accounting Policies
     The  interim financial information as of September 30, 2006,  and  for
     the  three  and  nine months ended September 30, 2006,  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, 2005.

     In September 2004, the Securities and Exchange Commission issued Staff
     Accounting  Bulletin No. 106 ("SAB 106"). SAB 106  expresses  the  SEC
     staff's views regarding SFAS No. 143 and its impact on both the  full-
     cost  ceiling  test  and  the calculation of  depletion  expense.   In
     accordance  with  SAB  106, beginning in the first  quarter  of  2005,
     undiscounted abandonment costs for wells to be drilled in  the  future
     to develop proved reserves are included in the unamortized cost of oil
     and  gas  properties, net of related salvage value,  for  purposes  of
     computing  depreciation,  depletion  and  amortization  ("DD&A").  The
     implementation  of  SAB  106 did not have a  material  impact  on  our
     financial statements.

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
involved.

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 September 30, 2006, 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
September 30, 2006, 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.

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 depletion, depreciation, and amortization
("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.

Operating Results
The  following  discussion  compares our results  for  the  quarters  ended
September  30,  2006 and 2005.  Unless otherwise indicated,  references  to
2006 and 2005 within this section refer to the respective quarterly period.

Income from net profits
Oil  and  gas  prices continued to climb to record levels compared  to  the
previous  two  years.  Comparing 2006 to 2005, oil and gas sales  decreased
$87,700,  of  which  price variances accounted for a $37,500  increase  and
production variances accounted for a $125,200 decrease.

Production  in  2006  (on a BOE basis) was 14% lower than  2005.   The  oil
volume  in  2006 was 20% lower than 2005 due primarily to two  wells  on  a
property that were down with mechanical problems.  Both wells were returned
to  production during the third quarter 2006.  Our gas production  was  11%
lower  in  2006  due primarily to normal production decline  in  one  field
partially offset by production from a new gas well.

In  2006,  our  realized  oil price was 13% higher  than  2005,  while  our
realized  gas price was 1% higher.  Historically, the markets for  oil  and
gas have been volatile, and they are likely to continue to be volatile.  We
have  very little control over the prices we receive for our production  at
the  wellhead since most of our physical marketing arrangements are market-
sensitive.

Oil  and gas production costs on a BOE basis increased from $13.71 per  BOE
in  2005 to $18.58 per BOE in 2006.  The increase in oil and gas production
costs is primarily due to a workover performed on an oil well.

Expenses
Depletion  on a BOE basis increased 13% in 2006.  Comparing 2006  to  2005,
depletion expense decreased $500, of which rate variances accounted  for  a
$2,600 increase and production variances accounted for a $3,100 decrease.

Accretion  expense increased 104% in 2006 due primarily to  fourth  quarter
2005  revisions in previous estimates related to increased  costs  to  plug
wells.

General  and administrative ("G&A") expenses were 17% higher in 2006.   The
increase in general and administrative expenses is primarily due to  higher
engineering and audit services.

Operating Results
The  following  discussion compares our results for the nine  months  ended
September  30,  2006 and 2005.  Unless otherwise indicated,  references  to
2006  and  2005  within  this  section refer to the  respective  nine-month
period.

Income from net profits
Oil  and  gas  prices continued to climb to record levels compared  to  the
previous  two  years.  Comparing 2006 to 2005, oil and gas sales  increased
$243,800,  of  which price variances accounted for a $332,400 increase  and
production variances accounted for a $88,600 decrease.

Production in 2006 (on a BOE basis) was 4% lower than 2005.

In  2006,  our  realized  oil price was 22% higher  than  2005,  while  our
realized gas price was 10% higher.  Historically, the markets for  oil  and
gas have been volatile, and they are likely to continue to be volatile.  We
have  very little control over the prices we receive for our production  at
the  wellhead since most of our physical marketing arrangements are market-
sensitive.

Oil  and gas production costs on a BOE basis increased from $12.29 per  BOE
in  2005 to $19.16 per BOE in 2006.  The increase in oil and gas production
costs in 2006 is due primarily to a workover performed on an oil well.

Expenses
Depletion  on  a BOE basis increased 7% in 2006.  Comparing 2006  to  2005,
depletion expense increased $2,200, of which rate variances accounted for a
$5,000 increase and production variances accounted for a $2,800 decrease.

Accretion  expense  increased 85% in 2006 due primarily to  fourth  quarter
2005  revisions in previous estimates related to increased  costs  to  plug
wells.

General  and administrative ("G&A") expenses were 12% higher in 2006.   The
increase in general and administrative expenses is primarily due to  higher
professional fees for audit, tax and engineering services.

Liquidity and Capital Resources

Texas Margin Taxes

In  May  2006, the State of Texas adopted House Bill 3, which modified  the
state's  franchise  tax  structure, replacing the  previous  tax  based  on
capital  or  earned  surplus with a margin tax  (the  "Texas  Margin  Tax")
effective with franchise tax reports filed on or after January 1, 2008. The
Texas  margin Tax is computed by applying the applicable tax rate  (1%  for
the  Partnership's  business)  to the profit  margin,  which  is  generally
determined  by total revenue less either cost of goods sold or compensation
as   applicable.   However  the  Partnership  believes,   based   on   it's
interpretation, that the Texas Margin Tax does not apply to the Partnership
since  substantially  all  of it's income is derived  from  a  net  profits
interest.

Recent Accounting Pronouncements

There  were  no  recent accounting pronouncements that  had  a  significant
effect 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.

Disclosure Controls and Procedures
The  Managing  General  Partner  has established  disclosure  controls  and
procedures   that  are  adequate  to  provide  reasonable  assurance   that
management will be able to collect, process and disclose both financial and
non-financial information, on a timely basis, in the Partnership's  reports
to  the  SEC.   Disclosure controls and procedures  include  all  processes
necessary  to  ensure  that material information  is  recorded,  processed,
summarized  and  reported within the time periods specified  in  the  SEC's
rules  and  forms,  and  is  accumulated and  communicated  to  management,
including our chief executive and chief financial officers, to allow timely
decisions regarding required disclosures.

     With respect to these disclosure controls and procedures:

          management  has  evaluated the effectiveness  of  the  disclosure
          controls  and procedures as of the end of the period  covered  by
          this report;

          this evaluation was conducted under the supervision and with  the
          participation  of management, including the chief  executive  and
          chief financial officers of the Managing General Partner; and

          it  is  the  conclusion of chief executive  and  chief  financial
          officers  of  the Managing General Partner that these  disclosure
          controls   and   procedures  are  effective  in   ensuring   that
          information  that is required to be disclosed by the  Partnership
          in   reports  filed  or  submitted  with  the  SEC  is  recorded,
          processed,  summarized  and  reported  within  the  time  periods
          specified in the rules and forms established by the SEC.

Internal Control Over Financial Reporting
There  has  not been any change in the Partnership's internal control  over
financial  reporting that occurred during the nine months  ended  September
30,  2006  that  has  materially  affected,  or  is  reasonably  likely  to
materially affect, its internal control over financial reporting.
