(a Delaware limited partnership)
Notes to Financial Statements
1. Organization
Southwest Oil & Gas 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

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 June 30, 2006, and for the
three and six months ended June 30, 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 Oil & Gas 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 on December 1, 1990 as part of a shelf offering
registered under the name Southwest Oil & Gas 1990-91 Income Program.
Minimum capital requirements for the Partnership were met on March 1, 1991,
and the offering of limited partnership interests concluded on September
30, 1991 with total limited partner contributions of $5,444,500.
The Partnership was formed to acquire 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 fluctuate 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 June 30, 2006, the net capitalized costs did not
exceed the estimated present value of oil and gas reserves.
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 the
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 June
30, 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
$46,200, of which price variances accounted for a $55,200 increase and
production variances accounted for a $9,000 decrease.
Production in 2006 (on a BOE basis) was 6% lower than 2005. We increased
our oil production in 2006 by 10% due primarily to improved performance
from one property. Our gas production decreased 25% in 2006 due primarily
to a production decline on a gas well.
In 2006, our realized oil price was 34% higher than 2005, while our
realized gas price was 1% lower. 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 decreased from $23.88 per BOE
in 2005 to $19.03 per BOE in 2006. The decrease in oil and gas production
costs was due primarily to workovers performed on two properties in 2005.
Expenses
Depletion on a BOE basis increased 3% in 2006. Comparing 2006 to 2005,
depletion expense decreased $200, of which rate variances accounted for a
$200 increase and production variances accounted for a $400 decrease.
Accretion expense increased 103% in 2006 due primarily to fourth quarter
2005 revisions in previous estimates related to increased costs to plug
wells.
General and administrative ("G&A") expenses were 23% higher in 2006 as
compared to 2005. The increase in general and administrative expenses is
primarily due to higher professional fees for audit and tax services.

Operating Results
The following discussion compares our results for the six months ended June
30, 2006 and 2005. Unless otherwise indicated, references to 2006 and 2005
within this section refer to the respective six months 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
$90,000, of which price variances accounted for a $102,800 increase and
production variances accounted for a $12,800 decrease.
Production in 2006 (on a BOE basis) was 4% lower than 2005. We increased
our oil production 3% in 2006 due primarily to improved performance from
one property. Our gas production decreased 15% in 2006 due primarily to
the production decline on a gas well.
In 2006, our realized oil price was 30% higher than 2005, while our
realized gas price was 5% 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 decreased from $20.45 per BOE
in 2005 to $16.23 per BOE in 2006. The decrease in oil and gas production
costs was due primarily to workovers performed on two properties in 2005.
Expenses
Depletion on a BOE basis increased 5% in 2006. Comparing 2006 to 2005,
depletion expense increased $100, of which rate variances accounted for a
$600 increase and production variances accounted for a $500 decrease.
Accretion expense increased 100% in 2006 due primarily to fourth quarter
2005 revisions in previous estimates related to increased costs to plug
wells.
General and administrative ("G&A") expenses were 14% higher in 2006 as
compared to 2005. The increase in general and administrative expenses is
primarily due to higher professional fees for audit and tax services.
Liquidity and Capital Resources
Partnership distributions during the six months ending June 30, 2006 were
$361,698, of which $325,604 was distributed to the limited partners and
$36,094 to the general partners. Cumulative cash distributions of
$6,789,817 have been made to the general and limited partners as of June
30, 2006. As of June 30, 2006, $6,151,378 or $564.92 per limited partner
unit has been distributed to the limited partners, representing 113% of
contributed capital.
Texas Margin Taxes
In May 2006, the State of Texas adopted House Bill 3, which modified the
state's franchise tax structure, replacing the previous tax based on
capital or earned surplus with a margin tax (the "Texas Margin Tax")
effective with franchise tax reports filed on or after January 1, 2008. The
Texas margin Tax is computed by applying the applicable tax rate (1% for
the Partnership's business) to the profit margin, which is generally
determined by total revenue less either cost of goods sold or compensation
as applicable. Although House Bill 3 states that the Texas Margin Tax is
not an income tax, the Partnership believes that Statement of Financial
Accounting Standards No. 109 "Accounting for Income Taxes" ("SFAS 109")
applies to the Texas Margin Tax. However the Partnership has determined
that the impact of the Texas Margin Tax on the deferred income tax
liabilities of the partnership is insignificant at June 30, 2006. The
Partnership may be required to record an income tax provision for the Texas
Margin Tax in future periods.
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
