Subsequent Events

The  Partnership, subsequent to September 30, 1998 sold its interest  in  a
portion   of  non-operated  oil  and  gas  properties.   The  Partnership's
interests  in  the  wells were sold for $49,703 net  proceeds,  after  post
closing adjustments.  The proceeds from the sale represented 8.79%  of  the
Partnership's total assets at December 31, 1997.



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.   For  the  quarter ended September  30,  1998,  the  net
capitalized  costs  did  not  exceed  the  estimated  present   value.    A
continuation  of  the oil price environment experienced  during  the  first
three  quarters  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 $65,180  from  $96,866
for  the  quarters  ended  September 30, 1998  and  1997,  respectively,  a
decrease  of  33%.  The principal factors affecting the comparison  of  the
quarters ended September 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 September 30, 1998 as  compared  to
    the  quarter  ended  September 30, 1997 by 33%, or  $5.86  per  barrel,
    resulting  in  a  decrease of approximately $15,800 in  revenues.   Oil
    sales  represented  35% of total oil and gas sales during  the  quarter
    ended  September 30, 1998 as compared to 50% during the  quarter  ended
    September 30, 1997.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    increased  during the same period by 4%, or $.09 per mcf, resulting  in
    an increase of approximately $2,200 in revenues.

    The net total decrease in revenues due to the change in prices received
    from oil and gas production is approximately $13,600.  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 30% during the 
    quarter ended September 30, 1998 as compared to the quarter ended 
    September 30, 1997, resulting in a decrease of approximately $9,600 
    in revenues.

    Gas production decreased approximately 5,200 mcf or 22% during the same
    period, resulting in a decrease of approximately $10,900 in revenues.

    The  total  decrease  in revenues due to the change  in  production  is
    approximately $20,500.  The decrease is primarily attributable to sharp
    natural decline and property sales.

Costs and Expenses

Total  costs  and  expenses  decreased to $59,687  from  $100,302  for  the
quarters  ended September 30, 1998 and 1997, respectively,  a  decrease  of
40%.   The  decrease  is  the  result of lower lease  operating  costs  and
depletion  expense,  partially  offset  by  an  increase  in  general   and
administrative expense.

1.    Lease  operating  costs  and production  taxes  were  47%  lower,  or
   approximately $34,300 less during the quarter ended September 30, 1998 as
   compared  to  the  quarter ended September 30, 1997.   The  decrease  is
   primarily attributable to the decline in oil prices, which has  made  it
   uneconomical to incur workover costs.

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
    39% or approximately $2,400 during the quarter ended September 30, 1998
    as  compared  to the quarter ended September 30, 1997. The increase  in
    general  and administrative costs are due largely to higher  accounting
    fees.   The  10-Q's  are  now  required to be  reviewed  based  on  new
    accounting pronouncements.

3.  Depletion  expense decreased to $12,000 for the quarter ended September
    30,  1998 from $19,000 for the same period in 1997.  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.



B.   General Comparison of the Nine Month Periods Ended September 30,  1998
and 1997

The  following  table  provides certain information  regarding  performance
factors for the nine month periods ended September 30, 1998 and 1997:

                                                 Nine Months
                                                    Ended        Percentage
                                                September 30,     Increase
                                                1998      1997   (Decrease)
                                                ----      ----   ---------
Average price per barrel of oil            $   12.27     19.40    (37%)
Average price per mcf of gas               $    2.00      2.17     (8%)
Oil production in barrels                      6,400     8,100    (21%)
Gas production in mcf                         55,900    73,000    (23%)
Gross oil and gas revenue                  $ 192,696   315,290    (39%)
Net oil and gas revenue                    $  66,574   128,675    (48%)
Partnership distributions                  $  57,784   141,500    (59%)
Limited partner distributions              $  52,084   127,350    (59%)
Per unit distribution to limited partners  $   18.46     45.14    (59%)
Number of limited partner units                2,821     2,821

Revenues

The  Partnership's oil and gas revenues decreased to $192,696 from $315,290
for  the  nine  months ended September 30, 1998 and 1997,  respectively,  a
decrease  of  39%.  The principal factors affecting the comparison  of  the
nine months ended September 30, 1998 and 1997 are as follows:

1.  The  average  price  for a barrel of oil received  by  the  Partnership
    decreased  during the nine months ended September 30, 1998 as  compared
    to  the  nine  months ended September 30, 1997 by  37%,  or  $7.13  per
    barrel,  resulting in a decrease of approximately $57,800 in  revenues.
    Oil sales represented 41% of total oil and gas sales during the quarter
    ended  September 30, 1998 as compared to 50% during the  quarter  ended
    September 30, 1997.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    decreased during the same period by 8%, or $.17 per mcf, resulting in a
    decrease of approximately $12,400 in revenues.

    The  total  decrease in revenues due to the change in  prices  received
    from oil and gas production is approximately $70,200.  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 1,700 barrels or 21% during the
    nine  months  ended September 30, 1998 as compared to the  nine  months
    ended  September  30,  1997, resulting in a decrease  of  approximately
    $20,900 in revenues.

    Gas  production  decreased approximately 17,100 mcf or 23%  during  the
    same  period,  resulting  in  a decrease of  approximately  $34,200  in
    revenues.

    The  total  decrease  in revenues due to the change  in  production  is
    approximately $55,100.  The decrease is primarily attributable to sharp
    natural decline and property sales.

Costs and Expenses

Total  costs and expenses increased to $280,057 from $278,905 for the  nine
months ended September 30, 1998 and 1997, respectively, an increase of less
than  1%.   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  32%  lower,   or
    approximately  $60,500 less during the nine months ended September  30,
    1998  as  compared to the nine months ended September  30,  1997.   The
    decrease is primarily attributable to the decline in oil prices,  which
    has made it uneconomical to incur workover costs.

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
    28%  or approximately $7,200 during the nine months ended September 30,
    1998  as  compared to the nine months ended September  30,  1997.   The
    increase in general and administrative costs are due largely to  higher
    accounting fees.  The 10-Q's are now required to be reviewed  based  on
    new accounting pronouncements.

3.  Depletion  expense  decreased to $60,000  for  the  nine  months  ended
    September  30,  1998 from $61,000 for the same period  in  1997.   This
    represents a decrease of 2%.  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.

4. The  net capitalized costs for the nine months ended September 30,  1998
   exceeded   the  estimated  present  value  of  oil  and  gas   reserves,
   discounted  at  10%  in the amount of $59,663, such  excess  costs  were
   charged  to current expense.  The write-down had the effect of  reducing
   net income, but did not affect cash flow or partner distributions.



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 $68,100  in
the  nine  months  ended  September 30, 1998 as compared  to  approximately
$153,400  in the nine months ended September 30, 1997.  The primary  source
of the 1998 cash flow from operating activities was profitable operations.

Cash flows used in investing activities were approximately $(3,200) in  the
nine  months ended September 30, 1998 as compared to approximately $(7,000)
in the nine months ended September 30, 1997.  The principle use of the 1997
cash  flow  from  investing  activities was  the  change  in  oil  and  gas
properties.

Cash  flows used in financing activities were approximately $57,800 in  the
nine  months ended September 30, 1998 as compared to approximately $141,400
in  the  nine  months ended September 30, 1997.  The only use in  financing
activities was the distributions to partners.

Total  distributions during the nine months ended September 30,  1998  were
$57,784 of which $52,084 was distributed to the limited partners and $5,700
to  the  general  partners.  The per unit distribution to limited  partners
during  the  nine  months  ended September  30,  1998  was  $18.46.   Total
distributions during the nine months ended September 30, 1997 were $141,500
of  which  $127,350 was distributed to the limited partners and $14,150  to
the general partners.  The per unit distribution to limited partners during
the nine months ended September 30, 1997 was $45.14.

The  sources  for  the  1998  distributions of $57,784  were  oil  and  gas
operations of approximately $68,100, partially offset by the change in  oil
and  gas  properties of approximately $3,200, resulting in excess cash  for
contingencies  or  subsequent  distributions.   The  source  for  the  1997
distributions  of  $141,500  was oil and gas  operations  of  approximately
$153,400,  partially  offset  by a change in  oil  and  gas  properties  of
approximately  $7,000,  resulting  in  excess  cash  for  contingencies  or
subsequent distributions.

Since  inception of the Partnership, cumulative monthly cash  distributions
of  $846,788  have  been made to the partners.  As of September  30,  1998,
$771,338  or $273.43 per limited partner unit has been distributed  to  the
limited partners, representing a 55% return of the capital contributed.

As  of  September  30, 1998, the Partnership had approximately  $30,200  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  Partnership  relies  on the Managing General Partner  for  their  data
processing  requirements.   This includes use of  a  program  designed  and
implemented  by Midland Southwest Software, the Managing General  Partner's
software subsidiary.  Midland Southwest Software currently has a year  2000
plan  in  effect.   They have surveyed existing programs and  hardware  and
estimate a compliance date of early 1999.  Determination of the total  cost
in connection with the year 2000 compliance issue is difficult to determine
due  to the fact that they are in the process of developing their new  1998
version  of  marketed  oil  and gas software, which  has,  from  inception,
included  year 2000 compliance.  Third party software programs utilized  by
the  Managing General Partner are either in compliance or are not  affected
by  the  year  2000,  with the exception of the payroll service,  which  is
currently modifying its system to accurately handle the Year 2000 issue.

The  Managing  General  Partner has not completed  its  evaluation  of  its
vendors  or  suppliers systems to determine the effect, if  any,  the  non-
compliance  of  such systems would have on the operations of  the  Managing
General  Partner.  Plans are under way to perform an audit in late 1998  or
early  1999  to determine the effect of non-compliance of its  vendors  and
suppliers  on the Managing General Partner and thus formulate a contingency
plan.

A  potential source of risk includes, but is not limited to, the  inability
of  principal  purchasers and suppliers to be year  2000  compliant,  which
could  have a material effect on the Managing General Partner's production,
cash  flow  and overall financial condition, notwithstanding  the  Managing
General  Partner's  actions to prepare its own  information  systems.   The
Managing  General  Partner currently does not have a  contingency  plan  in
place to cover any unforeseen problems encountered that relate to the  year
2000, but intends to produce one before the end of the fiscal year.
