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 workovers
during 1997 to enhance production.  The Partnership could possibly experience
the following changes; a little less than normal decline in 1997, with no
decline in 1998 and thereafter, experience a steady decline.

Revenues

The Partnership's income from net profits interests decreased to $50,042 from
$109,254 for the quarters ended June 30, 1997 and 1996, respectively, a
decrease of 54%.  The principal factors affecting the comparison of the
quarters ended June 30, 1997 and 1996 are as follows:

1.  The average price for a barrel of oil received by the Partnership
    decreased during the quarter ended June 30, 1997 as compared to the
    quarter ended June 30, 1996 by 10%, or $1.96 per barrel, resulting in a
    decrease of approximately $9,200 in income from net profits interests. 
    Oil sales represented 47% of total oil and gas sales during the quarters
    ended June 30, 1997 and 1996.

    The average price for an mcf of gas received by the Partnership decreased
    during the same period by 7%, or $.14 per mcf, resulting in a decrease of
    approximately $7,300 in income from net profits interests.  

    The total decrease in income from net profits interests due to the change
    in prices received from oil and gas production is approximately $16,500. 
    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.

2.  Oil production decreased approximately 800 barrels or 17% during the
    quarter ended June 30, 1997 as compared to the quarter ended June 30,
    1996, resulting in a decrease of approximately $14,900 in income from net
    profits interests.

    Gas production decreased approximately 10,600 mcf or 20% during the same
    period, resulting in a decrease of approximately $21,000 in income from
    net profits interests.

    The total decrease in income from net profits interests due to the change
    in production is approximately $35,900.  The decrease is primarily a
    result of the sharp natural decline of one well and downtime due to
    mechanical problems on another well.

3.  Lease operating costs and production taxes were 8% higher, or
    approximately $7,700 more during the quarter ended June 30, 1997 as
    compared to the quarter ended June 30, 1996.  The increase is primarily
    attributable to the pulling expense incurred on an injector well during
    1997.

Costs and Expenses

Total costs and expenses decreased to $46,702 from $71,560 for the quarters
ended June 30, 1997 and 1996, respectively, a decrease of 35%.  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 6%
    or approximately $800 during the quarter ended June 30, 1997 as compared
    to the quarter ended June 30, 1996.  

2.  Depletion expense decreased to $33,000 for the quarter ended June 30,
    1997 from $57,000 for the same period in 1996.  This represents a
    decrease of 42%.  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
    decrease in oil and gas revenues and the increase in the price of oil
    used to determine the Partnership's reserves for January 1, 1997 as
    compared to 1996.

Revenues

The Partnership's income from net profits interests decreased to $152,129
from $241,686 for the six months ended June 30, 1997 and 1996, respectively,
a decrease of 37%.  The principal factors affecting the comparison of the six
months ended June 30, 1997 and 1996 are as follows:

1.  The average price for a barrel of oil received by the Partnership
    increased during the six months ended June 30, 1997 as compared to the
    six months ended June 30, 1996 by 8%, or $1.51 per barrel, resulting in
    an increase of approximately $16,600 in income from net profits
    interests.  Oil sales represented 49% of total oil and gas sales during
    the six months ended June 30, 1997 as compared to 48% during the six
    months ended June 30, 1996.

    The average price for an mcf of gas received by the Partnership increased
    during the same period by 4%, or $.08 per mcf, resulting in an increase
    of approximately $8,400 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 $25,000. 
    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 2,500 barrels or 23% during the
    six months ended June 30, 1997 as compared to the six months ended June
    30, 1996, resulting in a decrease of approximately $51,200 in income from
    net profits interests.

    Gas production decreased approximately 22,500 mcf or 21% during the same
    period, resulting in a decrease of approximately $49,700 in income from
    net profits interests.

    The total decrease in income from net profits interests due to the change
    in production is approximately $100,900.  The decrease is primarily a
    result of property sales, the sharp natural decline of one well and
    downtime due to mechanical problems on another well.  

3.  Lease operating costs and production taxes were 7% higher, or
    approximately $13,000 more during the six months ended June 30, 1997 as
    compared to the six months ended June 30, 1996.  The increase is
    primarily attributable to the pulling expense incurred on an injector
    well during 1997.

Costs and Expenses

Total costs and expenses decreased to $110,767 from $150,782 for the six
months ended June 30, 1997 and 1996, respectively, a decrease of 27%.  The
decrease is the result of lower depletion expense, partially offset by an
increase in 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 1%
    or approximately $200 during the six months ended June 30, 1997 as
    compared to the six months ended June 30, 1996.

2.  Depletion expense decreased to $77,000 for the six months ended June 30,
    1997 from $117,000 for the same period in 1996.  This represents a
    decrease of 34%.  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
    decrease in oil and gas revenues and the increase in the price of oil
    used to determine the Partnership's reserves for January 1, 1997 as
    compared to 1996.

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 $210,000 in
the six months ended June 30, 1997 as compared to approximately $181,000 in
the six months ended June 30, 1996.  The primary source of the 1997 cash flow
from operating activities was profitable operations.

There were no cash flows provided by investing activities in the six months
ended June 30, 1997 as compared to approximately $5,800 in the six months
ended June 30, 1996.  

Cash flows used in financing activities were approximately $207,000 in the
six months ended June 30, 1997 as compared to approximately $212,100 in the
six months ended June 30, 1996.  The only use in financing activities was the
distributions to partners.

Total distributions during the six months ended June 30, 1997 were $207,000
of which $186,300 was distributed to the limited partners and $20,700 to the
general partners.  The per unit distribution to limited partners during the
six months ended June 30, 1997 was $34.39.  Total distributions during the
six months ended June 30, 1996 were $212,103 of which $195,953 was
distributed to the limited partners and $16,150 to the general partners.  The
per unit distribution to limited partners during the six months ended June
30, 1996 was $36.17.  

The source for the 1997 distributions of $207,000 was oil and gas operations
of approximately $210,000, resulting in excess cash for contingencies or
subsequent distributions.  The sources for the 1996 distributions of $212,103
were oil and gas operations of approximately $181,000, the sale of oil and
gas properties of approximately $5,800 and excess capital of $48,070,
resulting in excess cash for contingencies or subsequent distributions.

Since inception of the Partnership, cumulative monthly cash distributions of
$1,198,492 have been made to the partners.  As of June 30, 1997, $1,094,642
or $202.04 per limited partner unit has been distributed to the limited
partners, representing a 40% return of the capital contributed.

As of June 30, 1997, the Partnership had approximately $119,600 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.
