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.

Based  on  current  conditions,  management  anticipates  performing   some
workovers  during  2001.  The  Partnership will  most  likely  continue  to
experience a historical decline of 10% 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.

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.   The  Partnership's  capitalized  cost  did  not  exceed
estimated present value of reserves as of June 30, 2001.

A.  General Comparison of the Quarters Ended June 30, 2001 and 2000

The  following  table  provides certain information  regarding  performance
factors for the quarters ended June 30, 2001 and 2000:

Revenues

The  Partnership's oil and gas revenues decreased to $58,870  from  $74,641
for the quarters ended June 30, 2001 and 2000, respectively, a decrease  of
21%.   The principal factors affecting the comparison of the quarters ended
June 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 June 30, 2001 as  compared  to  the
    quarter ended June 30, 2000 by 7%, or $1.75 per barrel, resulting in  a
    decrease  of  approximately $1,800 in revenues.  Oil sales  represented
    36%  of total oil and gas sales during the quarter ended June 30,  2001
    as compared to 42% during the quarter ended June 30, 2000.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    increased  during the same period by 7%, or $.28 per mcf, resulting  in
    an increase of approximately $2,800 in revenues.

    The net total increase in revenues due to the change in prices received
    from  oil and gas production is approximately $1,000.  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 200 barrels or 17%  during  the
    quarter  ended June 30, 2001 as compared to the quarter ended June  30,
    2000, resulting in a decrease of approximately $5,200 in revenues.

    Gas  production decreased approximately 900 mcf or 8% during  the  same
    period, resulting in a decrease of approximately $3,600 in revenues.

    The  total  decrease  in revenues due to the change  in  production  is
    approximately  $8,800. The decrease in oil production is due  primarily
    to steep natural decline of several small wells.

Costs and Expenses

Total costs and expenses increased to $58,576 from $57,956 for the quarters
ended  June  30,  2001  and 2000, respectively, an  increase  of  1%.   The
increase  is  the result of higher general and administrative  expense  and
depletion expense, partially offset by a decrease in lease operating costs.

1.  Lease  operating  costs  and  production  taxes  were  23%  lower,   or
    approximately $11,600 less during the quarter ended June  30,  2001  as
    compared  to  the  quarter ended June 30, 2000.  The decline  in  lease
    operating cost is due to repairs and maintenance performed in 2000.

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 increased 6%
    or  approximately  $300  during the quarter  ended  June  30,  2001  as
    compared to the quarter ended June 30, 2000.

3.  Depletion expense increased to $14,000 for the quarter ended  June  30,
    2001  from  $2,000  for the same period in 2000.   This  represents  an
    increase  of 600%.  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 July 1, 2001 as compared to 2000.

Number of limited partner units               2,821     2,821

Revenues

The  Partnership's oil and gas revenues increased to $155,726 from $136,028
for  the six months ended June 30, 2001 and 2000, respectively, an increase
of  14%.  The principal factors affecting the comparison of the six  months
ended June 30, 2001 and 2000 are as follows:

1.  The  average  price  for a barrel of oil received  by  the  Partnership
    decreased during the six months ended June 30, 2001 as compared to  the
    six months ended June 30, 2000 by 2%, or $.42 per barrel, resulting  in
    a  decrease  of approximately $800 in revenues.  Oil sales  represented
    32%  of  total oil and gas sales during the six months ended  June  30,
    2001 as compared to 42% during the six months ended June 30, 2000.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    increased during the same period by 58%, or $1.93 per mcf, resulting in
    an increase of approximately $38,800 in revenues.

    The net total increase in revenues due to the change in prices received
    from oil and gas production is approximately $38,000.  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 200 barrels or 9% during the six
    months ended June 30, 2001 as compared to the six months ended June 30,
    2000, resulting in a decrease of approximately $5,100 in revenues.

    Gas production decreased approximately 3,900 mcf or 16% during the same
    period, resulting in a decrease of approximately $12,900 in revenues.

    The  total  decrease  in revenues due to the change  in  production  is
    approximately $18,000.

Costs and Expenses

Total  costs  and expenses increased to $105,151 from $87,785 for  the  six
months ended June 30, 2001 and 2000, respectively, an increase of 20%.  The
increase  is  the  result  of higher lease operating  costs  and  depletion
expense,  partially  offset  by a decrease in  general  and  administrative
expense.

1.  Lease  operating  costs  and  production  taxes  were  5%  higher,   or
    approximately $3,400 more during the six months ended June 30, 2001  as
    compared to the six months ended June 30, 2000.

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
    less than 1% or approximately $40 during the six months ended June  30,
    2001 as compared to the six months ended June 30, 2000.

3.  Depletion  expense increased to $23,000 for the six months  ended  June
    30,  2001 from $9,000 for the same period in 2000.  This represents  an
    increase  of 156%.  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 July 1, 2001 as compared to  2000,  and
    the increase 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 $96,300  in
the six months ended June 30, 2001 as compared to approximately $46,800  in
the  six  months ended June 30, 2000.  The primary source of the 2001  cash
flow from operating activities was profitable operations.

Cash flows used in investing activities were approximately $800 in the  six
months  ended June 30, 2001 as compared to approximately $600  in  the  six
months  ended June 30, 2000.  The principle use of the 2001 cash flow  from
investing activities was the additions to oil and gas properties.

Cash  flows used in financing activities were approximately $98,500 in  the
six  months ended June 30, 2001 as compared to approximately $30,000 in the
six  months ended June 30, 2000.  The only use in financing activities  was
the distributions to partners.

Total  distributions during the six months ended June 30, 2001 were $98,500
of  which $88,650 was distributed to the limited partners and $9,850 to the
general partners.  The per unit distribution to limited partners during the
six  months ended June 30, 2001 was $31.43. Total distributions during  the
six  months  ended  June  30,  2000  were  $30,000  of  which  $27,000  was
distributed  to  the limited partners and $3,000 to the  general  partners.
The  per unit distribution to limited partners during the six months  ended
June 30, 2000 was $9.57.

The source for the 2001 distributions of $98,500 was oil and gas operations
of  approximately  $96,300, and the change in oil  and  gas  properties  of
approximately $(800), with the balance from available cash on hand  at  the
beginning of the period. The sources for the 2000 distributions of  $30,000
were oil and gas operations of approximately $46,800 and the change in  oil
and  gas  properties of approximately $(600), resulting in excess cash  for
contingencies or subsequent distributions.

Since  inception of the Partnership, cumulative monthly cash  distributions
of  $1,190,825  have  been made to the partners.   As  of  June  30,  2001,
$1,084,912 or $384.58 per limited partner unit has been distributed to  the
limited partners, representing a 77% return of the capital contributed.

As  of  June 30, 2001, the Partnership had approximately $51,900 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.

Item 3.   Quantitative and Qualitative Disclosures About Market Risk
