                      Notes to Financial Statements


1.   Organization
     Southwest  Royalties  Institutional  Income  Fund  VII-B,   L.P.   was

2.   Summary of Significant Accounting Policies
     The interim financial information as of September 30, 2001 and for the
     three and nine months ended September 30, 2001, is unaudited.  Certain
     information  and footnote disclosures normally included  in  financial
     statements  prepared in accordance with generally accepted  accounting
     principles  have been condensed or omitted in this Form 10-Q  pursuant
     to   the   rules  and  regulations  of  the  Securities  and  Exchange
     Commission.   However,  in  the opinion of management,  these  interim
     financial  statements include all the necessary adjustments to  fairly
     present  the  results of the interim periods and all such  adjustments
     are  of a normal recurring nature.  The interim consolidated financial
     statements  should  be read in conjunction with the audited  financial
     statements for the year ended December 31, 2000.


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 does not  anticipate  performing
workovers during the next twelve months.  The Partnership has the potential
of  remaining steady for the next few years before possibly experiencing  a
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 September 30 2001, the net capitalized  costs  did
not exceed the estimated present value of oil and gas reserves.

Revenues

The  Partnership's income from net profits interests decreased to  $154,856
from  $238,150  for  the  quarters  ended  September  30,  2001  and  2000,
respectively,  a  decrease  of 35%.  The principal  factors  affecting  the
comparison  of  the  quarters ended September 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 September 30, 2001 as compared  to
     the  quarter  ended  September 30, 2000 by 19%, or $5.78  per  barrel,
     resulting  in a decrease of approximately $42,200 in income  from  net
     profits  interests.  Oil sales represented 83% of total  oil  and  gas
     sales  during the quarter ended September 30, 2001 as compared to  64%
     during the quarter ended September 30, 2000.

     The  average  price  for  an mcf of gas received  by  the  Partnership
     decreased  during the same period by 49%, or $2.44 per mcf,  resulting
     in  a  decrease  of approximately $34,900 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
     $77,100.  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  increased approximately 400 barrels or  6%  during  the
   quarter  ended  September  30, 2001 as compared  to  the  quarter  ended
   September  30,  2000, resulting in an increase of approximately  $12,100
   in income from net profits interests.

    Gas production decreased approximately 9,100 mcf or 39% during the same
    period, resulting in a decrease of approximately $45,000 in income from
    net profits interests.

    The  net total decrease in income from net profits interests due to the
    change  in  production is approximately $32,900.  The decrease  in  gas
    production  is due to an adjustment of gas balancing for a non-operated
    lease.

3.  Lease  operating  costs  and  production  taxes  were  10%  lower,   or
    approximately $7,100 less during the quarter ended September  30,  2001
    as compared to the quarter ended September 30, 2000.

Costs and Expenses

Total costs and expenses increased to $64,726 from $50,425 for the quarters
ended  September 30, 2001 and 2000, respectively, an increase of 28%.   The
increase  is  the  result  of  higher depletion  expense  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 1%
    or  approximately $300 during the quarter ended September 30,  2001  as
    compared to the quarter ended September 30, 2000.

2.  Depletion  expense increased to $36,000 for the quarter ended September
    30, 2001 from $22,000 for the same period in 2000.  This represents  an
    increase  of 64%.  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 October 1, 2001 as compared to 2000, and
    the decrease in oil and gas revenues received by the Partnership during
    2001 as compared to 2000.



B.   General Comparison of the Nine Month Periods Ended September 30,  2001
and 2000

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

                                                 Nine Months
                                                    Ended        Percentage
                                                September 30,     Increase
                                                2001      2000   (Decrease)
                                                ----      ----   ---------
Average price per barrel of oil            $   25.68     28.12     (9%)
Average price per mcf of gas               $    4.36      3.98      10%
Oil production in barrels                     21,200    21,400     (1%)
Gas production in mcf                         49,700    62,000    (20%)
Income from net profits interests          $ 566,392   639,878    (11%)
Partnership distributions                  $ 625,000   385,000      62%
Limited partner distributions              $ 562,500   346,500      62%
Per unit distribution to limited partners  $   37.50     23.10      62%
Number of limited partner units               15,000    15,000

Revenues.

The  Partnership's income from net profits interests decreased to  $566,392
from  $639,878  for  the nine months ended September  30,  2001  and  2000,
respectively,  a  decrease  of 11%.  The principal  factors  affecting  the
comparison  of  the nine months ended September 30, 2001 and  2000  are  as
follows:

1.  The  average  price  for a barrel of oil received  by  the  Partnership
    decreased  during the nine months ended September 30, 2001 as  compared
    to the nine months ended September 30, 2000 by 9%, or $2.44 per barrel,
    resulting  in  a decrease of approximately $51,700 in income  from  net
    profits  interests.  Oil sales represented 72% of  total  oil  and  gas
    sales  during the nine months ended September 30, 2001 as  compared  to
    71% during the nine months ended September 30, 2000.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    increased during the same period by 10%, or $.38 per mcf, resulting  in
    an  increase  of  approximately $18,900  in  income  from  net  profits
    interests.

    The  net total decrease in income from net profits interests due to the
    change  in prices received from oil and gas production is approximately
    $32,800.   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 200 barrels or  1%  during  the
   nine  months  ended September 30, 2001 as compared to  the  nine  months
   ended  September  30,  2000,  resulting in a decrease  of  approximately
   $5,600 in income from net profits interests.

    Gas  production  decreased approximately 12,300 mcf or 20%  during  the
    same period, resulting in a decrease of approximately $49,000 in income
    from net profits interests.

    The  total  decrease in income from net profits interests  due  to  the
    change  in  production is approximately $54,600.  The decrease  in  gas
    production  is due to an adjustment of gas balancing for a non-operated
    lease.

3.  Lease   operating  costs  and  production  taxes  were  7%  lower,   or
    approximately  $13,700 less during the nine months ended September  30,
    2001 as compared to the nine months ended September 30, 2000.

Costs and Expenses

Total  costs and expenses increased to $166,339 from $149,171 for the  nine
months ended September 30, 2001 and 2000, respectively, an increase of 12%.
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 4%
    or approximately $3,800 during the nine months ended September 30, 2001
    as compared to the nine months ended September 30, 2000.

2.  Depletion  expense  increased to $80,000  for  the  nine  months  ended
    September  30,  2001 from $59,000 for the same period  in  2000.   This
    represents an increase of 36%.  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 October 1, 2001 as compared
    to  2000,  and  the decrease 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 $579,100  in
the  nine  months  ended  September 30, 2001 as compared  to  approximately
$525,300  in the nine months ended September 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
nine months ended September 30, 2001.  There were no cash flows provided by
investing  activities  in  the nine months ended September  30,  2000.  The
principle  source of the 2001 cash flow from investing activities  was  the
change in oil and gas properties.

Cash flows used in financing activities were approximately $625,800 in  the
nine  months ended September 30, 2001 as compared to approximately $384,800
in  the  nine  months ended September 30, 2000.  The only use in  financing
activities was the distributions to partners.

Total  distributions during the nine months ended September 30,  2001  were
$625,000  of  which  $562,500 was distributed to the limited  partners  and
$62,500  to  the  general partners.  The per unit distribution  to  limited
partners during the nine months ended September 30, 2001 was $37.50.  Total
distributions during the nine months ended September 30, 2000 were $385,000
of  which  $346,500 was distributed to the limited partners and $38,500  to
the general partners.  The per unit distribution to limited partners during
the nine months ended September 30, 2000 was $23.10.

The  source  for  the  2001  distributions of  $625,000  was  oil  and  gas
operations  of  approximately  $579,100 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  $385,000  was oil and gas  operations  of  approximately
$525,300,  resulting  in  excess  cash  for  contingencies  and  subsequent
distributions.

Since  inception of the Partnership, cumulative monthly cash  distributions
of  $10,692,566 have been made to the partners.  As of September 30,  2001,
$9,638,220 or $642.55 per limited partner unit has been distributed to  the
limited partners, representing a 129% return of the capital contributed.

As  of  September 30, 2001, the Partnership had approximately  $205,300  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.
