2.   Summary of Significant Accounting Policies
     The interim financial information as of March 31, 2006, and for the
     three   months  ended  March  31,  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 decline 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 March 31, 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 March 31, 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
March 31, 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 increased
$186,700, of which price variances accounted for a $188,900 increase and
production variances accounted for a $2,200 decrease.

Production  in  2006  (on  a BOE basis) was  1%  lower  than  2005.   We
increased  our  oil  production  in  2006  due  primarily  to   improved
performance  on a well.  Our gas production was 4% lower  in  2006  than
2005 due primarily to normal production declines.

In  2006,  our  realized oil price was 24% higher than 2005,  while  our
realized  gas price was 30% 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 $7.39 per BOE
in  2005  to  $15.02  per  BOE in 2006.  The increase  in  oil  and  gas
production  costs  in  2006 was due primarily to  well  repairs  on  six
properties.

Expenses
Depletion on a BOE basis increased 6% in 2006.  Comparing 2006 to  2005,
depletion  expense  increased $1,100, of which rate variances  accounted
for  a  $1,400 increase and production variances accounted  for  a  $300
decrease.

Accretion  expense increased 66% in 2006 due primarily to  revisions  in
previous estimates related to increased costs to plug wells.

General and administrative ("G&A") expenses were 5% higher in 2006.

Liquidity and Capital Resources
Partnership distributions during the quarter ending March 31, 2006  were
$575,000, of which $517,500 was distributed to the limited partners  and
$57,500  to  the  general partners.  Cumulative  cash  distributions  of
$21,903,986  have been made to the general and limited  partners  as  of
March  31,  2006.   As  of March 31, 2006, $19,729,291  or  $986.46  per
limited  partner  unit  has been distributed to  the  limited  partners,
representing 197% of contributed capital.

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

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 quarter  ended  March  31,
2006 that has materially affected, or is reasonably likely to materially
affect, its internal control over financial reporting.
