Item 2.   Management's  Discussion and Analysis of Financial Condition  and
          Results of Operations

General

Southwest  Royalties Institutional Income Fund XI-A, L.P. (the Partnership)
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  Royalties
Institutional 1992-93 Income Program.  Minimum capital requirements for the
Partnership  were met on December 10, 1992 and the offering  concluding  on
April 30, 1993 with total limited partner contributions of $2,709,000.

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.

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.

Based  on  current  conditions,  management  anticipates  performing   some
workovers  during  2001.  The  Partnership  could  possibly  experience   a
historical decline of 12% 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  the
estimated present value of reserves as of June 30, 2001.

Revenues

The  Partnership's income from net profits interests decreased  to  $49,281
from $70,475 for the quarters ended June 30, 2001 and 2000, respectively, a
decrease  of  30%.  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 9%, or $2.38 per barrel, resulting in  a
    decrease  of approximately $3,800 in income from net profits interests.
    Oil sales represented 31% and 33% of total oil and gas sales during the
    quarters ended June 30, 2001 and 2000.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    increased  during the same period by 7%, or $.27 per mcf, resulting  in
    an  increase  of  approximately  $5,500  in  income  from  net  profits
    interests.

    The  net total increase in income from net profits interests due to the
    change  in prices received from oil and gas production is approximately
    $1,700.   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 50 barrels or  3%  during  the
    quarter  ended June 30, 2001 as compared to the quarter ended June  30,
    2000,  resulting in a decrease of approximately $1,300 in  income  from
    net profits interests.

    Gas production decreased approximately 2,800 mcf or 12% during the same
    period, resulting in a decrease of approximately $11,100 in income from
    net profits interests.

    The  total  decrease in income from net profits interests  due  to  the
    change in production is approximately $12,400.

3.  Lease  operating  costs  and  production  taxes  were  11%  lower,   or
    approximately  $8,100 less during the quarter ended June  30,  2001  as
    compared to the quarter ended June 30, 2000.

Costs and Expenses

Total costs and expenses increased to $29,724 from $14,380 for the quarters
ended  June  30,  2001 and 2000, respectively, an increase  of  107%.   The
increase  is  the result of higher general and administrative  expense  and
depletion expense.

1.  General and administrative costs consists of independent accounting and
    engineering  fees,  computer services, postage,  and  Managing  General
    Partner personnel costs.  General and administrative costs increased 3%
    or  approximately  $300  during the quarter  ended  June  30,  2001  as
    compared to the quarter ended June 30, 2000.

2.  Depletion expense increased to $19,000 for the quarter ended  June  30,
    2001  from  $4,000  for the same period in 2000.   This  represents  an
    increase  of 375%.  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.

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 8%, or $2.18 per barrel, resulting in
    a   decrease  of  approximately  $7,200  in  income  from  net  profits
    interests.  Oil sales represented 28% of total oil and gas sales during
    the  six  months ended June 30, 2001 as compared to 37% 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 48%, or $1.70 per mcf, resulting in
    an  increase  of  approximately $69,200  in  income  from  net  profits
    interests.

    The  net total increase in income from net profits interests due to the
    change  in prices received from oil and gas production is approximately
    $62,000.   The market price for oil and gas has been extremely volatile
    over  the  past  decade, and management expects  a  certain  amount  of

2.  Oil production decreased approximately 300 barrels or 8% during the six
    months ended June 30, 2001 as compared to the six months ended June 30,
    2000,  resulting in a decrease of approximately $8,100 in  income  from
    net profits interests.

Costs and Expenses

Total  costs  and expenses increased to $52,845 from $36,796  for  the  six
months ended June 30, 2001 and 2000, respectively, an increase of 44%.  The
increase  is  the  result  of  higher depletion  expense  and  general  and
administrative expense.

1.  General and administrative costs consists of independent accounting and
    engineering  fees,  computer services, postage,  and  Managing  General
    Partner  personnel costs.  General and administrative  costs  increased

2.  Depletion  expense increased to $32,000 for the six months  ended  June
    30, 2001 from $16,000 for the same period in 2000.  This represents  an
    increase  of 100%.  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 $193,400  in
the six months ended June 30, 2001 as compared to approximately $108,300 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 financing activities were approximately $210,000 in  the
six months ended June 30, 2001 as compared to approximately $100,000 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 $210,000
of  which  $189,000 was distributed to the limited partners and $21,000  to
the general partners.  The per unit distribution to limited partners during
the  six months ended June 30, 2001 was $34.88. Total distributions  during
the  six  months  ended June 30, 2000 were $100,000 of  which  $90,000  was
distributed  to  the limited partners and $10,000 to the general  partners.
The  per unit distribution to limited partners during the six months  ended
June 30, 2000 was $16.61.

The  source  for  the  2001  distributions of  $210,000  was  oil  and  gas
operations of approximately $193,400, with the balance from available  cash
on  hand  at  the  beginning  of  the period.  The  sources  for  the  2000
distributions  of  $100,000  were oil and gas operations  of  approximately
$108,300,   resulting  in  excess  cash  for  contingencies  or  subsequent
distributions.

Since  inception of the Partnership, cumulative monthly cash  distributions
of  $2,149,443  have  been made to the partners.   As  of  June  30,  2001,
$1,960,189 or $361.79 per limited partner unit has been distributed to  the
limited partners, representing a 72% return of the capital contributed.

As  of  June 30, 2001, the Partnership had approximately $98,000 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.
