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 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.

A.  General Comparison of the Quarters Ended September 30, 1995 and 1994

The following table provides certain information regarding performance
factors for the quarters ended September 30, 1995 and 1994:

Net Profits Interests

The Partnership's income (loss) from net profits interests decreased to
$(25,204) from $76,327 for the quarters ended September 30, 1995 and 1994,
respectively, a decrease of 133%.  The principal factors affecting the
comparison of the quarters ended September 30, 1995 and 1994 are as follows:

1.  The average price for a barrel of oil received by the Partnership
    decreased during the quarter ended September 30, 1995 as compared to the
    quarter ended September 30, 1994 by 3%, or $.44 per barrel, resulting in
    a decrease of approximately $5,500 in income from net profits interests. 
    Oil sales represented 88% of total oil and gas sales during the quarters
    ended September 30, 1995 and 1994.

    The average price for an mcf of gas received by the Partnership increased
    during the same period by 12%, or $.21 per mcf, resulting in an increase
    of approximately $3,400 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
    $2,100.  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 800 barrels or 6% during the
    quarter ended September 30, 1995 as compared to the quarter ended
    September 30, 1994, resulting in an increase of approximately $13,100 in
    income from net profits interests.

    Gas production decreased approximately 1,400 mcf or 9% during the same
    period, resulting in a decrease of approximately $2,800 in income from
    net profits interests.

    The net total increase in income from net profits interests due to the
    change in production is approximately $10,300.

3.  Lease operating costs and production taxes were 68% higher, or
    approximately $109,400 more during the quarter ended September 30, 1995
    as compared to the quarter ended September 30, 1994.  The increase is a
    result of workover costs incurred in 1995.

Costs and Expenses

Total costs and expenses decreased to $54,948 from $89,064 for the quarters
ended September 30, 1995 and 1994, respectively, a decrease of 38%.  The
decrease is the result of a decrease in general and administrative expense
and depletion.

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 6%
    or approximately $1,100 during the quarter ended September 30, 1995 as
    compared to the quarter ended September 30, 1994.

2.  Depletion expense decreased to $37,000 for the quarter ended
    September 30, 1995 from $70,000 for the same period in 1994.  This
    represents a decrease of 47%.  Depletion is calculated using the gross
    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.  Although oil and
    gas revenues increased for the quarter ended September 30, 1995 as
    compared to the quarter ended September 30, 1994, the decrease in
    depletion expense is the result of the change in oil prices since 1994.

Net Profits Interests

The Partnership's income from net profits interests increased to $277,451
from $234,722 for the nine months ended September 30, 1995 and 1994,
respectively, an increase of 18%.  The principal factors affecting the
comparison of the nine months ended September 30, 1995 and 1994 are as
follows:

1.  The average price for a barrel of oil received by the Partnership
    increased during the nine months ended September 30, 1995 as compared to
    the nine months ended September 30, 1994 by 11%, or $1.68 per barrel,
    resulting in an increase of approximately $63,500 in income from net
    profits interests.  Oil sales represented 88% of total oil and gas sales
    during the nine months ended September 30, 1995 as compared to 85% during
    the nine months ended September 30, 1994.

    The average price for an mcf of gas received by the Partnership increased
    during the same period by 7%, or $.14 per mcf, resulting in an increase
    of approximately $7,400 in income from net profits interests.  

    The total increase in income from net profits interests due to the change
    in prices received from oil and gas production is approximately $70,900. 
    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 increased approximately 6,100 barrels or 16% during the
    nine months ended September 30, 1995 as compared to the nine months ended
    September 30, 1994, resulting in an increase of approximately $103,300 in
    income from net profits interests.

    Gas production decreased approximately 4,700 mcf or 9% during the same
    period, resulting in a decrease of approximately $9,500 in income from
    net profits interests.

    The net total increase in income from net profits interests due to the
    change in production is approximately $93,800.  The increase is a result
    of successful workovers.

3.  Lease operating costs and production taxes were 28% higher, or
    approximately $121,900 more during the nine months ended September 30,
    1995 as compared to the nine months ended September 30, 1994.  The
    increase is a result of workover costs incurred in 1995.

Costs and Expenses

Total costs and expenses decreased to $191,591 from $267,691 for the nine
months ended September 30, 1995 and 1994, respectively, a decrease of 28%. 
The decrease is the result of a decrease in general and administrative
expense and depletion.

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 6%
    or approximately $4,100 during the nine months ended September 30, 1995
    as compared to the nine months ended September 30, 1994.

2.  Depletion expense decreased to $127,000 for the nine months ended
    September 30, 1995 from $199,000 for the same period in 1994.  This
    represents a decrease of 36%.  Depletion is calculated using the gross
    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.  Although oil and
    gas revenues increased during the nine months ended September 30, 1995 as
    compared to the nine months ended September 30, 1994, the decrease in
    depletion expense is the result of the change in oil prices since 1994.

Liquidity and Capital Resources

The primary source of cash is from profitable operations.  The Partnership
knows of no material change, nor does it anticipate any such change.

Cash flows provided by operating activities were approximately $210,800 in
the nine months ended September 30, 1995 as compared to approximately
$206,200 in the nine months ended September 30, 1994.  Primary source of the
1995 cash flow from operating activities was profitable operations.

ended September 30, 1995 as compared to none in the nine months ended
September 30, 1994.

Cash flows used in financing activities were approximately $253,600 in the
nine months ended September 30, 1995 as compared to approximately $159,500 in
the nine months ended September 30, 1994.  The only use in financing
activities was the distributions to partners.

Total distributions during the nine months ended September 30, 1995 were
$253,453, of which $231,003 was distributed to the limited partners and
$22,450 was distributed to the general partners.  The per unit distribution

to limited partners during the nine months ended September 30, 1994 was
$14.15.  The sources for the 1995 distributions of $253,453 were oil and gas
operations of approximately $210,800 and sales of oil and gas properties of
$48,400, resulting in excess cash for contingencies or subsequent
distributions.  The source for the 1994 distributions of $159,500 was oil and
gas operations of approximately $206,200, resulting in excess cash for
contingencies or subsequent distributions.

Since inception of the Partnership, cumulative monthly cash distributions of
$4,039,863 have been made to the partners.  As of September 30, 1995,
$3,653,189 or $360.03 per limited partner unit has been distributed to the
limited partners, representing a 72% return of the capital contributed.

As of September 30, 1995, the Partnership had approximately $106,700 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.
