Notes to Financial Statements
1. Organization
Southwest Royalties Institutional Income Fund X-B, L.P. was organized
under the laws of the state of Delaware on November 27, 1990 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 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., a wholly owned subsidiary of Clayton Williams Energy, Inc.,
serves as the Managing General Partner. Revenues, costs and expenses
are allocated as follows:
Limited General
Partners Partners
-------- --------
Interest income on capital 100% -

All other costs 90% 10%
(1)All organization costs in excess of 3% of initial capital
contributions will be paid by the Managing General Partner and
will be treated as a capital contribution. The Partnership paid
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 General Partner and
will be treated as a capital contribution.
2. Summary of Significant Accounting Policies
The interim financial information as of March 31, 2006, and for the
three months ended March 31, 2006, 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 Partnership's Annual Report on Form 10-K for
the year ended December 31, 2005.
In September 2004, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 106 ("SAB 106"). SAB 106 expresses the SEC
staff's views regarding SFAS No. 143 and its impact on both the full-
cost ceiling test and the calculation of depletion expense. In
accordance with SAB 106, beginning in the first quarter of 2005,
undiscounted abandonment costs for wells to be drilled in the future
to develop proved reserves are included in the unamortized cost of oil
and gas properties, net of related salvage value, for purposes of
computing depreciation, depletion and amortization ("DD&A"). The
implementation of SAB 106 did not have a material impact on our
financial statements.

Item 2. Management's Discussion and Analysis of Financial Condition and
Results of Operations
General
Southwest Royalties Institutional Income Fund X-B, L.P. was organized as a
Delaware limited partnership on November 27, 1990. The offering of such
limited partnership interests began December 1, 1990 as part of a shelf
offering registered under the name Southwest Royalties Institutional 1990-
91 Income Program. Minimum capital requirements for the Partnership were
met on March 11, 1991, with the offering of limited partnership interests
concluding September 30, 1991, with total limited partner contributions of
$5,590,500.
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. The economic
life of the Partnership thus depends on the period over which the
Partnership's oil and gas reserves are economically recoverable.
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 farm-out 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 decline in later years based on these factors.
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
sold.
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 March 31, 2006, the net capitalized costs did not
exceed the estimated present value of oil and gas reserves.
The Partnership's interest in oil and gas properties consists of net
profits interests in proved properties located within the continental
United States. A net profits interest is created when the owner of a
working interest in a property enters into an arrangement providing that
the net profits interest owner will receive a stated percentage of the net
profit from the property. The net profits interest owner will not
otherwise participate in additional costs and expenses of the property.
The Partnership recognizes income from its net profits interest in oil and
gas property on an accrual basis, while the quarterly cash distributions of
the net profits interest are based on a calculation of actual cash received
from oil and gas sales, net of expenses incurred during that quarterly
period. If the net profits interest calculation results in expenses
incurred exceeding the oil and gas income received during a quarter, no
cash distribution is due to the Partnership's net profits interest until
the deficit is recovered from future net profits. The Partnership accrues
a quarterly loss on its net profits interest provided there is a cumulative
net amount due for accrued revenue as of the balance sheet date. As of
March 31, 2006, there were no timing differences, which resulted in a
deficit net profit interest.
Critical Accounting Policies
The Partnership follows the full cost method of accounting for its oil and
gas properties. The full cost method subjects companies to quarterly
calculations of a "ceiling", or limitation on the amount of properties that
can be capitalized on the balance sheet. If the Partnership's capitalized
costs are in excess of the calculated ceiling, the excess must be written
off as an expense.
The Partnership's discounted present value of its proved oil and natural
gas reserves is a major component of the ceiling calculation, and
represents the component that requires the most subjective judgments.
Estimates of reserves are forecasts based on engineering data, projected
future rates of production and the timing of future expenditures. The
process of estimating oil and natural gas reserves requires substantial
judgment, resulting in imprecise determinations, particularly for new
discoveries. Different reserve engineers may make different estimates of
reserve quantities based on the same data. The Partnership's reserve
estimates are prepared by outside consultants.
The passage of time provides more qualitative information regarding
estimates of reserves, and revisions are made to prior estimates to reflect
updated information. However, there can be no assurance that more
significant revisions will not be necessary in the future. If future
significant revisions are necessary that reduce previously estimated
reserve quantities, it could result in a full cost property writedown. In
addition to the impact of these estimates of proved reserves on calculation
of the ceiling, estimates of proved reserves are also a significant
component of the calculation of depletion, depreciation, and amortization
("DD&A").
While the quantities of proved reserves require substantial judgment, the
associated prices of oil and natural gas reserves that are included in the
discounted present value of the reserves do not require judgment. The
ceiling calculation dictates that prices and costs in effect as of the last
day of the period are generally held constant indefinitely. Because the
ceiling calculation dictates that prices in effect as of the last day of
the applicable quarter are held constant indefinitely, the resulting value
is not indicative of the true fair value of the reserves. Oil and natural
gas prices have historically been cyclical and, on any particular day at
the end of a quarter, can be either substantially higher or lower than the
Partnership's long-term price forecast that is a barometer for true fair
value.

Operating Results
The following discussion compares our results for the quarters ended March
31, 2006 and 2005. Unless otherwise indicated, references to 2006 and 2005
within this section refer to the respective quarterly period.
Income from net profits
Oil and gas prices continued to climb to record levels compared to the
previous two years. Comparing 2006 to 2005, oil and gas sales increased
$94,000, of which price variances accounted for a $91,500 increase and
production variances accounted for a $2,500 increase.
Production in 2006 (on a BOE basis) was less than 1% lower than 2005. We
increased our oil production in 2006 by 4% due primarily to improved
performance on one property. Our gas production was 8% lower in 2006 than
2005 due primarily to normal production decline.
In 2006, our realized oil price was 30% higher than 2005, while our
realized gas price was 22% higher. Historically, the markets for oil and
gas have been volatile, and they are likely to continue to be volatile. We
have very little control over the prices we receive for our production at
the wellhead since most of our physical marketing arrangements are market-
sensitive.
Oil and gas production costs on a BOE basis increased from $15.42 per BOE
in 2005 to $15.87 per BOE in 2006. The increase in oil and gas production
costs in 2006 was due primarily to increased production tax costs related
to higher product prices.
Expenses
Depletion on a BOE basis remained the same for 2006.
Accretion expense increased 88% in 2006 due primarily to revisions in
previous estimates related to increased costs to plug wells.
General and administrative ("G&A") expenses were 4% higher in 2006 as
compared to 2005.
Liquidity and Capital Resources
Partnership distributions during the quarter ending March 31, 2006 were
$225,000, of which $202,500 was distributed to the limited partners and
$22,500 to the general partners. Cumulative cash distributions of
$7,168,023 have been made to the general and limited partners as of March
31, 2006. As of March 31, 2006, $6,511,112 or $582.34 per limited partner
unit has been distributed to the limited partners, representing 116% of
contributed capital.
Recent Accounting Pronouncements
There were no recent accounting pronouncements that had a significant
effect on the partnership.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
The Partnership is not a party to any derivative or embedded derivative
instruments.
Item 4. Controls and Procedures
The Managing General Partner has established disclosure controls and
procedures that are adequate to provide reasonable assurance that
management will be able to collect, process and disclose both financial and
non-financial information, on a timely basis, in the Partnership's reports
to the SEC. Disclosure controls and procedures include all processes
necessary to ensure that material information is recorded, processed,
summarized and reported within the time periods specified in the SEC's
rules and forms, and is accumulated and communicated to management,
including our chief executive and chief financial officers, to allow timely
decisions regarding required disclosures.
With respect to these disclosure controls and procedures:
management has evaluated the effectiveness of the disclosure
controls and procedures as of the end of the period covered by
this report;
this evaluation was conducted under the supervision and with the
participation of management, including the chief executive and
chief financial officers of the Managing General Partner; and
it is the conclusion of chief executive and chief financial
officers of the Managing General Partner that these disclosure
controls and procedures are effective in ensuring that
information that is required to be disclosed by the Partnership
in reports filed or submitted with the SEC is recorded,
processed, summarized and reported within the time periods
specified in the rules and forms established by the SEC.
Internal Control Over Financial Reporting
There has not been any change in the Partnership's internal control over
financial reporting that occurred during the quarter ended March 31, 2006
that has materially affected, or is reasonably likely to materially affect,
its internal control over financial reporting.
