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 does not  anticipate  performing
workovers during 1998.  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.  The Partnership reduced the net capitalized costs of  oil
and  gas  properties  in the quarter ended June 30, 1998  by  approximately
$59,663.  The write-down has the effect of reducing net income, but did not
affect  cash  flow  or  distributions.  A continuation  of  the  oil  price
environment experienced during the first half of 1998 will have an  adverse
affect  on  the Company's revenues and operating cash flow.  Also,  further
declines in oil prices could result in additional decreases in the carrying
value of the Company's oil and gas properties.

Revenues

The  Partnership's oil and gas revenues decreased to $55,974  from  $98,419
for the quarters ended June 30, 1998 and 1997, respectively, a decrease  of
43%.   The principal factors affecting the comparison of the quarters ended
June 30, 1998 and 1997 are as follows:

1.  The  average  price  for a barrel of oil received  by  the  Partnership
    decreased  during the quarter ended June 30, 1998 as  compared  to  the
    quarter ended June 30, 1997 by 35%, or $6.53 per barrel, resulting in a
    decrease  of  approximately $17,000 in revenues.  Oil sales represented
    49%  of total oil and gas sales during the quarter ended June 30,  1998
    as compared to 50% during the quarter ended June 30, 1997.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    decreased during the same period by 16%, or $.31 per mcf, resulting  in
    a decrease of approximately $7,700 in revenues.

    The  total  decrease in revenues due to the change in  prices  received
    from oil and gas production is approximately $24,700.  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 400 barrels or 15%  during  the
    quarter  ended June 30, 1998 as compared to the quarter ended June  30,
    1997, resulting in a decrease of approximately $4,900 in revenues.

    Gas production decreased approximately 7,600 mcf or 31% during the same
    period, resulting in a decrease of approximately $12,800 in revenues.

    The  total  decrease  in revenues due to the change  in  production  is
    approximately  $17,700.   The decrease in gas production  is  primarily
    attributable  to the sale of one well, another well being  plugged  and
    abandoned and one major well being shut-in for 30 days.

Costs and Expenses

Total  costs  and  expenses  increased to $136,889  from  $88,966  for  the
quarters  ended June 30, 1998 and 1997, respectively, an increase  of  54%.
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  35%  lower,   or
    approximately $21,400 less during the quarter ended June  30,  1998  as
    compared to the quarter ended June 30, 1997.  The decrease is primarily
    attributable to the pulling expense incurred on an injector well during
    1997.

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
    59%  or approximately $3,900 during the quarter ended June 30, 1998  as
    compared  to the quarter ended June 30, 1997.  Increase in general  and
    administrative costs are the result of higher accounting  fees  due  to
    the  necessity of contracting out preparation of tax depletion and  K-1
    schedules.

3.  Depletion expense increased to $26,000 for the quarter ended  June  30,
    1998  from  $19,000  for the same period in 1997.  This  represents  an
    increase  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 increase in depletion expense between the  comparative
    periods  were  the decrease in the price of oil used to  determine  the
    Partnership's reserves for January 1, 1998 as compared  to  1997.   The
    Partnership reduced the net capitalized costs of oil and gas properties
    in the quarter ended June 30, 1998 by approximately $59,663.  The write-
    down  has  the effect of reducing net income, but did not  affect  cash
    flow or distributions.

Revenues

The  Partnership's oil and gas revenues decreased to $127,515 from $218,425
for  the  six months ended June 30, 1998 and 1997, respectively, a decrease
of  42%.  The principal factors affecting the comparison of the six  months
ended June 30, 1998 and 1997 are as follows:

1.  The  average  price  for a barrel of oil received  by  the  Partnership
    decreased during the six months ended June 30, 1998 as compared to  the
    six  months ended June 30, 1997 by 39%, or $7.79 per barrel,  resulting
    in  an  decrease  of  approximately $42,100  in  revenues.   Oil  sales
    represented 44% of total oil and gas sales during the six months  ended
    June  30, 1998 as compared to 50% during the six months ended June  30,
    1997.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    decreased during the same period by 13%, or $.30 per mcf, resulting  in
    a decrease of approximately $14,700 in revenues.

    The  total  decrease in revenues due to the change in  prices  received
    from oil and gas production is approximately $56,800.  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 900 barrels or 17%  during  the
    six months ended June 30, 1998 as compared to the six months ended June
    30, 1997, resulting in a decrease of approximately $11,100 in revenues.

    Gas  production  decreased approximately 11,900 mcf or 24%  during  the
    same  period,  resulting  in  a decrease of  approximately  $23,100  in
    revenues.

    The  total  decrease  in revenues due to the change  in  production  is
    approximately  $34,200.   The decrease in gas production  is  primarily
    attributable  to the sale of one well, another well being  plugged  and
    abandoned and one major well being shut-in for 30 days.

Costs and Expenses

Total  costs and expenses increased to $220,369 from $178,605 for  the  six
months ended June 30, 1998 and 1997, respectively, an increase of 23%.  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 $26,200 less during the six months ended June 30, 1998 as
    compared  to  the  six  months ended June 30, 1997.   The  decrease  is
    primarily  attributable to the pulling expense incurred on an  injector
    well during 1997.

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
    24%  or approximately $4,800 during the six months ended June 30,  1998
    as compared to the six months ended June 30, 1997.  Increase in general
    and  administrative costs are the result of higher accounting fees  due
    to the necessity of contracting out preparation of tax depletion and K-
    1 schedules.

3.  Depletion  expense increased to $48,000 for the six months  ended  June
    30, 1998 from $42,000 for the same period in 1997.  This represents  an
    increase  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 increase in depletion expense between the  comparative
    periods  was  the  decrease in the price of oil used to  determine  the
    Partnership's reserves for January 1, 1998 as compared  to  1997.   The
    Partnership reduced the net capitalized costs of oil and gas properties
    in the quarter ended June 30, 1998 by approximately $59,663.  The write-
    down  has  the effect of reducing net income, but did not  affect  cash
    flow or distributions.

<PAGE>
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 $48,300  in
the six months ended June 30, 1998 as compared to approximately $123,900 in
the  six  months ended June 30, 1997.  The primary source of the 1998  cash
flow from operating activities was profitable operations.

Cash  flows used in investing activities were approximately $4,800  in  the
six  months ended June 30, 1998 as compared to approximately $4,200 in  the
six  months ended June 30, 1997.  The principle use of the 1998  cash  flow
from  investing  activities was the additions to oil  and  gas  properties,
partially offset by the sale of oil and gas properties.

Cash  flows used in financing activities were approximately $46,800 in  the
six months ended June 30, 1998 as compared to approximately $118,000 in the
six  months ended June 30, 1997.  The only use in financing activities  was
the distributions to partners.

Total  distributions during the six months ended June 30, 1998 were $46,784
of  which $42,184 was distributed to the limited partners and $4,600 to the
general partners.  The per unit distribution to limited partners during the
six  months ended June 30, 1998 was $14.95.  Total distributions during the
six  months  ended  June  30,  1997 were $118,000  of  which  $106,200  was
distributed  to  the limited partners and $11,800 to the general  partners.
The  per unit distribution to limited partners during the six months  ended
June 30, 1997 was $37.65.

The  sources  for  the  1998  distributions of $46,784  were  oil  and  gas
operations  of  approximately $48,300 less the net change in  oil  and  gas
properties of approximately $4,800, with the balance from available cash on
hand at the beginning of the period.  The source for the 1997 distributions
of $118,000 was oil and gas operations of approximately $123,900, partially
offset by the net change in oil and gas properties of approximately $4,200,
resulting in excess cash for contingencies or subsequent distributions.

Since  inception of the Partnership, cumulative monthly cash  distributions
of  $835,788 have been made to the partners.  As of June 30, 1998, $761,438
or  $269.92  per limited partner unit has been distributed to  the  limited
partners, representing a 54% return of the capital contributed.

As  of  June 30, 1998, the Partnership had approximately $21,900 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.

Information Systems for the Year 2000

The  Managing  General Partner provides all data processing  needs  of  the
Partnership.   The Managing General Partner has reviewed and evaluated  its
information  systems  to determine if its systems accurately  process  data
referencing   the   year   2000.   Primarily  all   necessary   programming
modifications  to  correct year 2000 referencing in  the  Managing  General
Partners  internal accounting and operating systems have been made to-date.
However  the  Managing General Partner has not completed its evaluation  of
its vendors and suppliers systems to determine the effect, if any, the non-
compliance  of  such systems would have on the operation  of  the  Managing
General Partnership or the operations of the Partnership.
