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   few
workovers during 2001 to enhance production.  Additional workovers  may  be
performed  in  the  year 2003.  The partnership may  have  an  increase  in
production volumes for the year 2003, otherwise, the partnership will  most
likely  experience  the historical production decline of approximately  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.  As of March 31, 2001, the net capitalized costs did  not
exceed the estimated present value of oil and gas reserves.

Revenues

The  Partnership's oil and gas revenues increased to $96,856  from  $61,385
for  the  quarters ended March 31, 2001 and 2000, respectively, an increase
of  58%.   The  principal factors affecting the comparison of the  quarters
ended March 31, 2001 and 2000 are as follows:

1.  The  average  price  for a barrel of oil received  by  the  Partnership
    decreased  during the quarter ended March 31, 2001 as compared  to  the
    quarter ended March 31, 2000 by 1%, or $.27 per barrel, resulting in  a
    decrease of approximately $300 in revenues.  Oil sales represented  24%
    of  total oil and gas sales during the quarter ended March 31, 2001  as
    compared to 41% during the quarter ended March 31, 2000.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    increased  during the same period by 141%, or $3.88 per mcf,  resulting
    in an increase of approximately $43,100 in revenues.

    The net total increase in revenues due to the change in prices received
    from oil and gas production is approximately $42,800.  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 70 barrels or  7%  during  the
    quarter ended March 31, 2001 as compared to the quarter ended March 31,
    2000, resulting in a decrease of approximately $1,800 in revenues.

    Gas production decreased approximately 2,000 mcf or 15% during the same
    period, resulting in a decrease of approximately $5,500 in income  from
    net profits interests.

    The  total  decrease  in revenues due to the change  in  production  is
    approximately $7,300.

Costs and Expenses

Total costs and expenses increased to $46,575 from $29,828 for the quarters
ended  March  31,  2001 and 2000, respectively, an increase  of  56%.   The
increase  is the result of higher lease operating costs, depletion expense,
partially offset by a decrease in general and administrative expense.

1.  Lease  operating  costs  and  production  taxes  were  82%  higher,  or
    approximately $15,000 more during the quarter ended March 31,  2001  as
    compared  to the quarter ended March 31, 2000.  The increase  in  lease
    operating expense is due to pulling expenses and maintenance on one non-
    operated  lease being performed in 2001 and the increase in  production
    taxes in relation to the increase in oil and gas sales 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 7%
    or  approximately  $300  during the quarter ended  March  31,  2001  as
    compared to the quarter ended March 31, 2000.

3.  Depletion  expense increased to $9,000 for the quarter ended March  31,
    2001  from  $7,000  for the same period in 2000.   This  represents  an
    increase  of 29%.  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.   A  contributing
    factor  to  the  increase of depletion expense between the  comparative
    periods were the increase in oil and gas revenue.

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 $62,900  in
the  quarter ended March 31, 2001 as compared to approximately  $31,800  in
the quarter ended March 31, 2000.  The primary source of the 2001 cash flow
from operating activities was profitable operations.

Cash  flows  used in investing activities were approximately  $400  in  the
quarter  ended in March 31, 2001 as compared to approximately $200  in  the
quarter ended March 31, 2000.

Cash  flows used in financing activities were $60,000 in the quarter  ended
March  31, 2001 as compared to $20,000 in the quarter ended March 31, 2000.
The only use in financing activities was the distributions to partners.

Total distributions during the quarter ended March 31, 2001 were $60,000 of
which  $54,000  was distributed to the limited partners and $6,000  to  the
general partners.  The per unit distribution to limited partners during the
quarter  ended March 31, 2001 was $19.14.  Total distributions  during  the
quarter  ended March 31, 2000 were $20,000 of which $18,000 was distributed
to  the limited partners and $2,000 to the general partners.  The per  unit
distribution  to limited partners during the quarter ended March  31,  2000
was $6.38.

The  sources  for  the  2001  distributions of $60,000  were  oil  and  gas
operations  of  approximately  $62,900,  resulting  in  excess   cash   for
contingencies or subsequent distributions to partners.  The sources for the
2000  distributions of $20,000 were oil and gas operations of approximately
$31,800,   resulting  in  excess  cash  for  contingencies  or   subsequent
distributions to partners.

Since  inception of the Partnership, cumulative monthly cash  distributions
of  $1,152,325  have  been made to the partners.  As  of  March  31,  2001,
$1,050,262 or $372.30 per limited partner unit has been distributed to  the
limited partners, representing a 74% return of the capital contributed.

As  of March 31, 2001, the Partnership had approximately $76,100 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.
