     The  interim financial information as of September 30, 2001,  and  for
     the  three  and  nine months ended September 30, 2001,  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 audited  financial
     statements for the year ended December 31, 2000.

 Item 2.   Management's Discussion and Analysis of Financial Condition  and
        Results of Operations
General
Southwest  Oil  & Gas Income Fund XI-A, L.P. was organized  as  a  Delaware
limited  partnership  on  May  5,  1992.   The  offering  of  such  limited
partnership  interests began August 20, 1992 as part of  a  shelf  offering
registered  under  the  name Southwest Oil & Gas  1992-93  Income  Program.
Minimum  capital  requirements for the Partnership were met  on  March  17,
1993,  with the offering of limited partnership interests concluding  April
30,  1993.   At  the  conclusion  of the offering  of  limited  partnership
interests, 122 limited partners had purchased 2,821 units for $1,410,500.

The  Partnership was formed to acquire 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.

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 farmout 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.

Management  does not anticipate performing workovers during the next  year.
The Partnership could possibly experience a 10%-12% decline.

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.

The  Partnership's policy for depreciation, depletion and  amortization  of
oil  and  gas  properties is computed under the units  of  revenue  method.
Under the units of revenue method, depreciation, depletion and amortization
is  computed  on  the  basis of current gross revenues from  production  in
relation  to future gross revenues, based on current prices, from estimated
production of proved oil and gas reserves.

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.  For the nine months ended September 30,  2001,  the  net
capitalized costs did not exceed the estimated present value.

Revenues

The  Partnership's oil and gas revenues decreased to $42,641  from  $80,199
for  the  quarters  ended  September 30, 2001  and  2000,  respectively,  a
decrease  of  47%.  The principal factors affecting the comparison  of  the
quarters ended September 30, 2001 and 2000 are as follows:

1.  The  average  price  for a barrel of oil received  by  the  Partnership
    decreased  during the quarter ended September 30, 2001 as  compared  to
    the  quarter  ended  September 30, 2000 by 24%, or  $7.24  per  barrel,
    resulting in a decrease of approximately $7,200 in revenues.  Oil sales
    represented  50%  of total oil and gas sales during the  quarter  ended
    September  30,  2001  as  compared to  38%  during  the  quarter  ended
    September 30, 2000.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    decreased during the same period by 45%, or $2.03 per mcf, resulting in
    a decrease of approximately $19,100 in revenues.

    The  total  decrease in revenues due to the change in  prices  received
    from oil and gas production is approximately $26,300.  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 30 barrels or 3% during the quarter
ended September 30, 2001 as compared to the quarter
   ended September 30, 2000, resulting in a decrease
of approximately $900 in revenues.

    Gas production decreased approximately 1,900 mcf or 17% during the same
    period, resulting in a decrease of approximately $8,600 in revenues.

    The  total  decrease  in revenues due to the change  in  production  is
    approximately $9,500.  The decrease in production is due  primarily  to
    sharp natural decline on one gas lease.

Costs and Expenses

Total costs and expenses increased to $49,200 from $20,315 for the quarters
ended September 30, 2001 and 2000, respectively, an increase of 142%.   The
increase  is  the  result of higher depletion expense and  lease  operating
costs,  partially  offset  by  a  decrease in  general  and  administrative
expense.

1.    Lease  operating  costs and production taxes  were  159%  higher,  or
   approximately $16,100 more during the quarter ended September 30, 2001 as
   compared to the quarter ended September 30, 2000. The increase in  lease
   operating  expense  is due to corrosive inhibitors and  maintenance  and
   repairs on three leases being performed in 2001.

2.  General and administrative costs consist of independent accounting  and
    engineering  fees,  computer services, postage,  and  Managing  General
    Partner personnel costs.  General and administrative costs decreased 5%
    or  approximately $200 during the quarter ended September 30,  2001  as
    compared to the quarter ended September 30, 2000.

3.  Depletion  expense increased to $19,000 for the quarter ended September
    30,  2001 from $6,000 for the same period in 2000.  This represents  an
    increase  of 217%.  Depletion is calculated using the units of  revenue
    method  of  amortization based on a percentage of current period  gross
    revenues  to  total future gross oil and gas revenues, as estimated  by
    the   Partnership's  independent  petroleum  consultants.  Contributing
    factors  to  the increase in depletion expense between the  comparative
    periods were the decrease in the price of oil and gas used to determine
    the Partnership's reserves for October 1, 2001 as compared to 2000, and
    the decrease in oil and gas revenues received by the Partnership during
    2001 as compared to 2000.

and 2000

The  following  table  provides certain information  regarding  performance
factors for the nine month periods ended September 30, 2001 and 2000:

                                                 Nine Months
                                                    Ended        Percentage

Partnership distributions                  $ 133,500    65,000     105%
Limited partner distributions              $ 120,150    58,500     105%
Per unit distribution to limited partners  $   42.59     20.74     105%
Number of limited partner units                2,821     2,821

Revenues

The  Partnership's oil and gas revenues decreased to $198,366 from $216,226
for  the  nine  months ended September 30, 2001 and 2000,  respectively,  a
decrease of 8%.  The principal factors affecting the comparison of the nine
months ended September 30, 2001 and 2000 are as follows:

1.  The  average  price  for a barrel of oil received  by  the  Partnership
    decreased  during the nine months ended September 30, 2001 as  compared
    to  the  nine  months ended September 30, 2000 by  14%,  or  $4.05  per
    barrel,  resulting in a decrease of approximately $12,600 in  revenues.
    Oil sales represented 37% of total oil and gas sales during the quarter
    ended  September 30, 2001 as compared to 42% during the  quarter  ended
    September 30, 2000.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    increased during the same period by 19%, or $.70 per mcf, resulting  in
    an increase of approximately $20,200 in revenues.

    The net total increase in revenues due to the change in prices received
    from  oil and gas production is approximately $7,600.  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.

<PAGE>

2.  Oil  production decreased approximately 160 barrels or  5%  during  the
    nine  months  ended September 30, 2001 as compared to the  nine  months
    ended  September  30,  2000, resulting in a decrease  of  approximately
    $4,500 in revenues.

    Gas production decreased approximately 5,800 mcf or 17% during the same
    period, resulting in a decrease of approximately $20,900 in revenues.

    The  total  decrease  in revenues due to the change  in  production  is
    approximately $25,400.  The decrease in production is due primarily  to
    sharp natural decline on one gas lease.

Costs and Expenses

Total  costs and expenses increased to $154,351 from $108,099 for the  nine
months ended September 30, 2001 and 2000, respectively, an increase of 43%.
The  increase is the result of higher depletion expense and lease operating
costs,  partially  offset  by  a  decrease in  general  and  administrative
expense.

1.  Lease  operating  costs  and  production  taxes  were  24%  higher,  or
    approximately  $19,500 more during the nine months ended September  30,
    2001  as  compared  to the nine months ended September  30,  2000.  The
    increase  in  lease  operating expense is due to  pulling  expense  and
    maintenance on two leases being performed in 2001.

2.  General and administrative costs consist of independent accounting  and
    engineering  fees,  computer services, postage,  and  Managing  General
    Partner personnel costs.  General and administrative costs decreased 2%
    or  approximately $200 during the nine months ended September 30,  2001
    as compared to the nine months ended September 30, 2000.

3.  Depletion  expense  increased to $42,000  for  the  nine  months  ended
    September  30,  2001 from $15,000 for the same period  in  2000.   This
    represents  an  increase of 180%.  Depletion is  calculated  using  the
    units  of  revenue  method of amortization based  on  a  percentage  of
    current  period  gross  revenues to total  future  gross  oil  and  gas
    revenues,  as  estimated  by  the Partnership's  independent  petroleum
    consultants. Contributing factors to the increase in depletion  expense
    between the comparative periods were the decrease in the price  of  oil
    and  gas  used to determine the Partnership's reserves for  October  1,
    2001  as  compared  to 2000, and the decrease in oil and  gas  revenues
    received by the Partnership during 2001 as compared to 2000.

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 $125,300  in
the  nine  months  ended  September 30, 2001 as compared  to  approximately
$99,900 in the nine months ended September 30, 2000.  The primary source of
the 2001 cash flow from operating activities was profitable operations.

Cash  flows used in investing activities were approximately $1,300  in  the
nine  months ended September 30, 2001 as compared to approximately  $18,600
in the nine months ended September 30, 2000.  The principle use of the 2001
cash  flow  from  investing  activities was  the  change  in  oil  and  gas
properties.

Cash flows used in financing activities were approximately $133,500 in  the
nine  months ended September 30, 2001 as compared to approximately  $65,000
in  the  nine  months ended September 30, 2000.  The only use in  financing
activities was the distributions to partners.

Total  distributions during the nine months ended September 30,  2001  were
$133,500  of  which  $120,150 was distributed to the limited  partners  and
$13,350  to  the  general partners.  The per unit distribution  to  limited
partners during the nine months ended September 30, 2001 was $42.59.  Total
distributions during the nine months ended September 30, 2000 were  $65,000
of  which $58,500 was distributed to the limited partners and $6,500 to the
general partners.  The per unit distribution to limited partners during the
nine months ended September 30, 2000 was $20.74.

The  source  for  the  2001  distributions of  $133,500  was  oil  and  gas
operations of approximately $125,300, partially offset by a change  in  oil
and  gas  properties  of  approximately $(1,300),  with  the  balance  from
available cash on hand at the beginning of the period.  The sources for the
2000  distributions of $65,000 were oil and gas operations of approximately
$99,900,  partially  offset  by the change in oil  and  gas  properties  of
approximately  $(18,600),  resulting in excess cash  for  contingencies  or
subsequent distributions.

Since  inception of the Partnership, cumulative monthly cash  distributions
of  $1,225,825 have been made to the partners.  As of September  30,  2001,
$1,116,412 or $395.75 per limited partner unit has been distributed to  the
limited partners, representing a 79% return of the capital contributed.

As  of  September  30, 2001, the Partnership had approximately  $29,000  in
working  capital.   The  Managing  General  Partner  knows  of  no  unusual
contractual commitments and believes the revenues generated from operations
are adequate to meet the needs of the Partnership.
