                      Notes to Financial Statements


1.   Organization
     Southwest  Royalties  Institutional  Income  Fund  VIII-B,  L.P.   was
     organized  under  the laws of the state of Delaware  on  November  30,
     1987,  for  the purpose of acquiring producing oil and gas  properties
     and to produce and market crude oil and natural gas produced from such
     properties  for a term of 50 years, unless terminated  at  an  earlier
     date  as  provided for in the Partnership Agreement.  The offering  of
     limited   partner   units  began  March  31,  1988,  minimum   capital
     requirements  were met July 11, 1988, with the offering  concluded  on
     March 31, 1989.

     The  Partnership  sells its oil and gas production  to  a  variety  of
     purchasers  with the prices it receives being dependent upon  the  oil
     and  gas  economy.  Southwest Royalties, Inc. serves as  the  Managing
     General  Partner  and  H. H. Wommack, III, as the  individual  general
     partner.  Revenues, costs and expenses are allocated as follows:

          the  Managing  General Partner an amount equal to 3%  of  initial
          capital contributions for such organization costs.

          (2)   Administrative costs in any year which exceed 2% of capital
          contributions shall be paid by the Managing Partner and  will  be

2.   Summary of Significant Accounting Policies
     The  interim  financial information as of June 30, 2001, and  for  the
     three  and  six  months  ended June 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 VIII-B, L.P. was organized as
a  Delaware limited partnership on November 30, 1987. The offering of  such
limited  partnership  interests  began  March  31,  1988,  minimum  capital
requirements were met July 11, 1988, and concluded on March 31,  1989  with
total limited partner contributions of $5,073,500.

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, 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 2001.  The Partnership could possibly experience a  normal
decline of 8% to 10% per year.

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.

Number of limited partner units              10,147     10,147

Revenues

The  Partnership's income from net profits interests decreased to  $117,517
from  $191,433 for the quarters ended June 30, 2001 and 2000, respectively,
a  decrease of 39%.  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 6%, or $1.53 per barrel, resulting in  a
    decrease of approximately $14,800 in income from net profits interests.
    Oil sales represented 84% of total oil and gas sales during the quarter
    ended  June  30, 2001 as compared to 85% during the quarter ended  June
    30, 2000.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    increased  during the same period by 4%, or $.17 per mcf, resulting  in
    an  increase  of  approximately  $1,800  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
    $13,000.   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 500 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 $13,800 in income  from
    net profits interests.

    Gas  production decreased approximately 800 mcf or 7% during  the  same
    period, resulting in a decrease of approximately $3,500 in income  from
    net profits interests.

    The  total  decrease in income from net profits interests  due  to  the
    change in production is approximately $17,300.

3.  Lease  operating  costs  and  production  taxes  were  33%  higher,  or
    approximately $46,100 more during the quarter ended June  30,  2001  as
    compared  to  the quarter ended June 30, 2000.  The increase  in  lease
    operating  cost  is due to major repair and maintenance  on  one  lease
    being performed in 2001.

Costs and Expenses

Total costs and expenses increased to $30,779 from $27,608 for the quarters
ended  June  30,  2001  and 2000, respectively, an increase  of  11%.   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
    13%  or approximately $2,800 during the quarter ended June 30, 2001  as
    compared to the quarter ended June 30, 2000.

2.  Depletion expense increased to $11,000 for the quarter ended  June  30,
    2001  from  $5,000  for the same period in 2000.   This  represents  an
    increase  of 120%.  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

    decreased during the six months ended June 30, 2001 as compared to  the
    six months ended June 30, 2000 by 2%, or $.57 per barrel, resulting  in
    a  decrease  of  approximately  $11,300  in  income  from  net  profits
    interests. Oil sales represented 82% of total oil and gas sales  during
    the  six  months ended June 30, 2001 as compared to 86% 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 42%, or $1.63 per mcf, resulting in
    an  increase  of  approximately $35,200  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
    $23,900.   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 2% during the six
    months ended June 30, 2001 as compared to the six months ended June 30,

    approximately $35,700 more 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 $60,943 from $57,043  for  the  six
months ended June 30, 2001 and 2000, respectively, an increase of 7%.   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%

2.  Depletion  expense increased to $22,000 for the six months  ended  June
    30, 2001 from $15,000 for the same period in 2000.  This represents  an
    increase  of 47%.  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 $355,100  in
the six months ended June 30, 2001 as compared to approximately $290,300 in
the  six  months ended June 30, 2000.  The primary source of the 2001  cash
flow from operating activities was profitable operations.

Cash flows used in financing activities were approximately $380,100 in  the
six months ended June 30, 2001 as compared to approximately $225,200 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 $380,000
of  which  $342,000 was distributed to the limited partners and $38,000  to
the general partners.  The per unit distribution to limited partners during
the  six months ended June 30, 2001 was $33.70. Total distributions  during
the  six  months  ended June 30, 2000 were $225,000 of which  $202,500  was
distributed  to  the limited partners and $22,500 to the general  partners.
The  per unit distribution to limited partners during the six months  ended
June 30, 2000 was $19.96.

The  sources  for  the  2001 distributions of $380,000  were  oil  and  gas
operations of approximately $355,100, with the balance from available  cash
on  hand  at  the  beginning  of  the period.   The  source  for  the  2000
distributions  of  $225,000  was oil and gas  operations  of  approximately
$290,300.

Since  inception of the Partnership, cumulative monthly cash  distributions
of  $6,791,823  have  been made to the partners.   As  of  June  30,  2001,
$6,133,125 or $604.43 per limited partner unit has been distributed to  the
limited partners, representing a 121% return of the capital contributed.

As  of June 30, 2001, the Partnership had approximately $209,800 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.
