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

General

Southwest Royalties Institutional Income Fund VII-B, L.P. was organized  as
a  Delaware limited partnership on January 28, 1987. The offering  of  such
limited  partnership  interests  began  March  23,  1987;  minimum  capital
requirements  were met May 20, 1987 and concluded December  1,  1987,  with
total limited partner contributions of $7,500,000.

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 farmout arrangements, sale 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   2001  to  enhance  production.   The  Partnership  could  possibly
experience a 9% normal 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.  As of June 30, 2001, the net capitalized costs  did  not
exceed the estimated present value of oil and gas reserves.

The  following  table  provides certain information  regarding  performance
factors for the quarters ended June 30, 2001 and 2000:

Revenues

The  Partnership's income from net profits interests decreased to  $193,208
from  $205,712 for the quarters ended June 30, 2001 and 2000, respectively,
a  decrease of 6%.  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 4%, or $1.16 per barrel, resulting in  a
    decrease  of approximately $8,000 in income from net profits interests.
    Oil sales represented 74% of total oil and gas sales during the quarter
    ended  June  30, 2001 as compared to 70% during the quarter ended  June
    30, 2000.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    decreased during the same period by 3%, or $.14 per mcf, resulting in a
    decrease of approximately $2,100 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
    $10,100.   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  5%  during  the
    quarter  ended June 30, 2001 as compared to the quarter ended June  30,
    2000,  resulting in a decrease of approximately $10,800 in income  from
    net profits interests.

    Gas production decreased approximately 4,400 mcf or 23% during the same
    period, resulting in a decrease of approximately $19,200 in income from
    net profits interests.

    The  total  decrease in income from net profits interests  due  to  the
    change  in  production is approximately $30,000.  The decrease  in  gas
    production  is due to an adjustment of gas balancing for a non-operated
    well.

3.  Lease  operating  costs  and  production  taxes  were  19%  lower,   or
    approximately $14,100 less during the quarter ended June  30,  2001  as
    compared  to  the  quarter ended June 30, 2000. The decrease  in  lease
    operating  cost  is  primarily the result of  repairs  and  maintenance
    performed during the second quarter of 2000.

Costs and Expenses

Total costs and expenses increased to $50,162 from $44,060 for the quarters
ended  June  30,  2001  and 2000, respectively, an increase  of  14%.   The
increase is the result of higher depletion expense, partially offset  by  a
decrease 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  decreased
    12%  or approximately $3,900 during the quarter ended June 30, 2001  as
    compared to the quarter ended June 30, 2000.

2.    Depletion expense increased to $21,000 for the quarter ended June 30,
   2001 from $11,000 for the same period in 2000.  This represents an increase
   of  91%.   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.


B.   General  Comparison of the Six Month Periods Ended June 30,  2001  and
2000

The  following  table  provides certain information  regarding  performance
factors for the six month periods ended June 30, 2001 and 2000:

Per unit distribution to limited
 partners                                $    28.50     11.10     157%
Number of limited partner units              15,000    15,000

Revenues

The  Partnership's income from net profits interests increased to  $411,536
from   $401,727  for  the  six  months  ended  June  30,  2001  and   2000,
respectively,  an  increase  of 2%.  The principal  factors  affecting  the
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 2%, or $.63 per barrel, resulting  in
    a   decrease  of  approximately  $8,700  in  income  from  net  profits
    interests.  Oil sales represented 68% of total oil and gas sales during
    the  six  months ended June 30, 2001 as compared to 73% 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 37%, or $1.40 per mcf, resulting in
    an  increase  of  approximately $47,000  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
    $38,300.   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 700 barrels or 5% during the six
    months ended June 30, 2001 as compared to the six months ended June 30,
    2000,  resulting in a decrease of approximately $19,000 in income  from
    net profits interests.

    Gas production decreased approximately 4,300 mcf or 11% during the same
    period, resulting in a decrease of approximately $16,200 in income from
    net profits interests.

    The  total  decrease in income from net profits interests  due  to  the
    change in production is approximately $35,200.

3.  Lease   operating  costs  and  production  taxes  were  5%  lower,   or
    approximately $6,600 less during the six months ended June 30, 2001  as
    compared to the six months ended June 30, 2000.

Costs and Expenses

Total  costs  and expenses increased to $101,610 from $98,746 for  the  six
months ended June 30, 2001 and 2000, respectively, an increase of 3%.   The
increase is the result of higher depletion expense, partially offset  by  a
decrease 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 decreased 7%
    or  approximately $4,100 during the six months ended June 30,  2001  as
    compared to the six months ended June 30, 2000.

2.  Depletion  expense increased to $44,000 for the six months  ended  June
    30, 2001 from $37,000 for the same period in 2000.  This represents  an
    increase  of 19%.  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 $418,900  in
the six months ended June 30, 2001 as compared to approximately $317,300 in
the  six  months ended June 30, 2000.  The primary source of the 2001  cash
flow from operating activities was profitable operations.

Cash flows provided by investing activities were approximately $100 in  the
six  months  ended  June 30, 2001.  There were no cash  flows  provided  by
investing  activities in the six months ended June 30, 2000. The  principle
source of the 2001 cash flow from investing activities was the sale of  oil
and gas properties.

Cash flows used in financing activities were approximately $474,800 in  the
six months ended June 30, 2001 as compared to approximately $184,900 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 $475,000
of  which  $427,500 was distributed to the limited partners and $47,500  to
the general partners.  The per unit distribution to limited partners during
the  six months ended June 30, 2001 was $28.50. Total distributions  during
the  six  months  ended June 30, 2000 were $185,000 of which  $166,500  was
distributed  to  the limited partners and $18,500 to the general  partners.
The  per unit distribution to limited partners during the six months  ended
June 30, 2000 was $11.10.

The  source  for  the  2001  distributions of  $475,000  was  oil  and  gas
operations  of  approximately  $418,900 and  the  change  in  oil  and  gas
properties of approximately $100, with the balance from available  cash  on
hand  at the beginning of the period. The source for the 2000 distributions
of $185,000 was oil and gas operations of approximately $317,300, resulting
in excess cash for contingencies or subsequent distributions.

Since  inception of the Partnership, cumulative monthly cash  distributions
of  $10,542,566  have  been made to the partners.  As  of  June  30,  2001,
$9,503,220 or $633.55 per limited partner unit has been distributed to  the
limited partners, representing a 127% return of the capital contributed.

As  of June 30, 2001, the Partnership had approximately $228,000 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.
