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.

Management  does not anticipate performing workovers during the next  year.
The Partnership could possibly experience a steady 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  quarter ended September  30,  2000,  the  net
capitalized costs did not exceed the estimated present value.

Results of Operations

A.  General Comparison of the Quarters Ended September 30, 2000 and 1999

The  following  table  provides certain information  regarding  performance
factors for the quarters ended September 30, 2000 and 1999:

                                                 Three Months

                                                ----      ----   ---------
Average price per barrel of oil            $   29.77     21.71     37%
Average price per mcf of gas               $    4.74      2.33    103%
Oil production in barrels                      1,700     2,060   (17%)
Gas production in mcf                         22,200    27,860   (20%)
Income from net profits interests          $  86,234    59,408     45%
Partnership distributions                  $  55,000    40,000     38%
Limited partner distributions              $  49,500    36,000     38%
Per unit distribution to limited partners  $    9.14      6.64     38%
Number of limited partner units                5,418     5,418

Revenues

The  Partnership's income from net profits interests increased  to  $86,234
from   $59,408  for  the  quarters  ended  September  30,  2000  and  1999,
respectively,  an  increase of 45%.  The principal  factors  affecting  the
comparison  of  the  quarters ended September 30,  2000  and  1999  are  as
follows:

1.   The  average  price  for a barrel of oil received by  the  Partnership
     increased  during the quarter ended September 30, 2000 as compared  to
     the  quarter  ended  September 30, 1999 by 37%, or $8.06  per  barrel,
     resulting in an increase of approximately $16,600 in income  from  net
     profits  interests.  Oil sales represented 32% of total  oil  and  gas
     sales  during the quarter ended September 30, 2000 as compared to  41%
     during the quarter ended September 30, 1999.

     The  average  price  for  an mcf of gas received  by  the  Partnership
     increased  during the same period by 103%, or $2.41 per mcf, resulting
     in  an  increase of approximately $67,100 in income from  net  profits
     interests.

     The  total  increase in income from net profits interests due  to  the
     change in prices received from oil and gas production is approximately
     $83,700.  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.

<PAGE>

2.  Oil  production decreased approximately 360 barrels or 17%  during  the
    quarter  ended  September 30, 2000 as compared  to  the  quarter  ended
    September 30, 1999, resulting in a decrease of approximately $10,700 in
    income from net profits interests.

    Gas production decreased approximately 5,660 mcf or 20% during the same
    period, resulting in a decrease of approximately $26,800 in income from
    net profits interests.

    The  total  decrease in income from net profits interests  due  to  the
    change  in  production  is  approximately  $37,500.   The  decrease  in
    production  is due to the decline of several small non-operated  wells,
    which  have  not had repairs and maintenance performed on them  due  to
    past price constraints.

3.  Lease  operating  costs  and  production  taxes  were  5%  higher,   or
    approximately $2,700 more during the quarter ended September  30,  2000
    as compared to the quarter ended September 30, 1999.

Costs and Expenses

Total costs and expenses decreased to $16,231 from $16,563 for the quarters
ended  September 30, 2000 and 1999, respectively, a decrease  of  2%.   The
decrease is the result of lower depletion expense, partially offset  by  an
increase in 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 7%
    or  approximately $700 during the quarter ended September 30,  2000  as
    compared to the quarter ended September 30, 1999.

2.  Depletion  expense decreased to $6,000 for the quarter ended  September
    30,  2000  from $7,000 for the same period in 1999.  This represents  a
    decrease  of 14%.  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  decline in depletion expense between the  comparative
    periods were the increase in the price of oil and gas used to determine
    the  Partnership's reserves and the increase in oil  and  gas  revenues
    received by the Partnership.

B.   General Comparison of the Nine Month Periods Ended September 30,  2000
and 1999

The  following  table  provides certain information  regarding  performance
factors for the nine month periods ended September 30, 2000 and 1999:

                                                 Nine Months
                                                    Ended        Percentage
                                                September 30,     Increase
                                                2000      1999   (Decrease)
                                                ----      ----   ---------
Average price per barrel of oil            $   27.85     14.82      88%
Average price per mcf of gas               $    3.75      2.05      83%
Oil production in barrels                      5,300     6,530    (19%)
Gas production in mcf                         68,500    79,660    (14%)
Income from net profits interests          $ 236,532   115,902     104%
Partnership distributions                  $ 155,000   124,960      24%
Limited partner distributions              $ 139,500   115,960      20%
Per unit distribution to limited partners  $   25.75     21.40      20%
Number of limited partner units                5,418     5,418

Revenues

The  Partnership's income from net profits interests increased to  $236,532
from  $115,902  for  the nine months ended September  30,  2000  and  1999,
respectively,  an  increase of 104%.  The principal factors  affecting  the
comparison  of  the nine months ended September 30, 2000 and  1999  are  as
follows:

1.  The  average  price  for a barrel of oil received  by  the  Partnership
    increased  during the nine months ended September 30, 2000 as  compared
    to  the  nine  months ended September 30, 1999 by 88%,  or  $13.03  per
    barrel,  resulting  in an increase of approximately $85,100  in  income
    from net profits interests.  Oil sales represented 36% of total oil and
    gas  sales during the nine months ended September 30, 2000 as  compared
    to 37% during the nine months ended September 30, 1999.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    increased during the same period by 83%, or $1.70 per mcf, resulting in
    an  increase  of  approximately $135,400 in  income  from  net  profits
    interests.

    The  total  increase in income from net profits interests  due  to  the
    change  in prices received from oil and gas production is approximately
    $220,500.  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 1,230 barrels or 19% during the
    nine  months  ended September 30, 2000 as compared to the  nine  months
    ended  September  30,  1999, resulting in a decrease  of  approximately
    $34,300 in income from net profits interests.

    Gas  production  decreased approximately 11,160 mcf or 14%  during  the
    same period, resulting in a decrease of approximately $41,900 in income
    from net profits interests.

    The  total  decrease in income from net profits interests  due  to  the
    change  in  production  is  approximately  $76,200.   The  decrease  in
    production is due primarily to natural decline.

3.  Lease  operating  costs  and  production  taxes  were  17%  higher,  or
    approximately  $24,200 more during the nine months ended September  30,
    2000 as compared to the nine months ended September 30, 1999.

Costs and Expenses

Total  costs  and expenses decreased to $53,027 from $67,825 for  the  nine
months ended September 30, 2000 and 1999, respectively, a decrease of  22%.
The  decrease is the result of lower 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 decreased 5%
    or approximately $1,800 during the nine months ended September 30, 2000
    as compared to the nine months ended September 30, 1999.

2.  Depletion  expense  decreased to $22,000  for  the  nine  months  ended
    September  30,  2000 from $35,000 for the same period  in  1999.   This
    represents a decrease of 37%.  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 decline in depletion expense  between  the
    comparative periods were the increase in the price of oil and gas  used
    to determine the Partnership's reserves and the increase in oil and gas
    revenues received by the Partnership.

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 $174,600  in
the  nine  months  ended  September 30, 2000 as compared  to  approximately
$91,400 in the nine months ended September 30, 1999.  The primary source of
the 2000 cash flow from operating activities was profitable operations.

There  were  no  cash flows provided by investing activities  in  the  nine
months  ended September 30, 2000.  Cash flows used in investing  activities
were approximately $5 in the nine months ended September 30, 1999.

Cash flows used in financing activities were approximately $154,800 in  the
nine  months ended September 30, 2000 as compared to approximately $125,000
in  the  nine  months ended September 30, 1999.  The only use in  financing
activities was the distributions to partners.

Total  distributions during the nine months ended September 30,  2000  were
$155,000  of  which  $139,500 was distributed to the limited  partners  and
$15,500  to  the  general partners.  The per unit distribution  to  limited
partners during the nine months ended September 30, 2000 was $25.75.  Total
distributions during the nine months ended September 30, 1999 were $124,960
of which $115,960 was distributed to the limited partners and $9,000 to the
general partners.  The per unit distribution to limited partners during the
nine months ended September 30, 1999 was $21.40.

The  sources  for  the  2000 distributions of $155,000  were  oil  and  gas
operations  of  approximately  $174,600,  resulting  in  excess  cash   for
contingencies  or  subsequent  distributions.   The  source  for  the  1999
distributions  of  $124,960  was oil and gas  operations  of  approximately
$91,400 and the change in oil and gas properties of approximately (5), with
the balance from available cash on hand at the beginning of the period.

Since  inception of the Partnership, cumulative monthly cash  distributions
of  $1,869,408 have been made to the partners.  As of September  30,  2000,
$1,708,158 or $315.27 per limited partner unit has been distributed to  the
limited partners, representing a 63% return of the capital contributed.

As  of  September 30, 2000, the Partnership had approximately  $140,100  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.


<PAGE>

Liquidity - Managing General Partner
The  Managing General Partner has a highly leveraged capital structure with
approximately, $33.8 million of cash interest and $5.9 million of principal
due  within  the  next  twelve  months.  The Managing  General  Partner  is
currently  in  the  process  of renegotiating  the  terms  of  its  various
obligations with its note holders and/or attempting to seek new lenders  or
equity  investors.   Additionally,  the  Managing  General  Partner   would
consider disposing of certain assets in order to meet its obligations.

There  can  be no assurance that the Managing General Partner's  continuing
debt  restructuring  efforts will be successful or that  the  lenders  will
agree  to  a course of action consistent with the Managing General Partners
requirements  in restructuring the obligations.  Even if such agreement  is
reached,  it  may  require approval of additional  lenders,  which  is  not
assured.   Furthermore, there can be no assurance that the sales of  assets
can  be  successfully  accomplished on terms  acceptable  to  the  Managing
General   Partner.   Under  current  circumstances,  the  Managing  General
Partner's  ability to continue as a going concern depends upon its  ability
to  (1)  successfully  restructure  its obligations  or  obtain  additional
financing  as  may  be  required, (2) maintain  compliance  with  all  debt
covenants, (3) generate sufficient cash flow to meet its obligations  on  a
timely  basis, and (4) achieve satisfactory levels of future earnings.   If
the  Managing  General Partner is unsuccessful in its efforts,  it  may  be
unable to meet its obligations making it necessary to undertake such  other
actions as may be appropriate to preserve asset values.
