                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)

1.  BUSINESS ORGANIZATION

  DESCRIPTION OF COMPANY

     W-H Energy Services, Inc., a Texas corporation, and its subsidiaries
(collectively, "W-H") is a diversified oilfield service company that provides
products and services used in connection with the drilling and completion of oil
and natural gas wells and the production of oil and natural gas. W-H has the
following primary lines of business: (1) drilling related products and services,
which include logging-while-drilling, measurement-while-drilling, directional
drilling, down-hole drilling motors, rental tools and drilling fluids; and (2)
completion and workover related products and services, which include cased-hole
wireline logging, perforating, tubing conveyed perforating and associated rental
equipment, polymers and specialty chemicals, rental tools and coiled tubing.

  BASIS OF PRESENTATION

     The unaudited Consolidated Financial Statements have been prepared in
accordance with accounting principles generally accepted in the United States
for interim financial information and the instructions to Form 10-Q and Rule 10
of Regulation S-X. Accordingly, they do not include all of the information and
footnotes required by accounting principles generally accepted in the United
States for complete financial statements. For further information, refer to the
Consolidated Financial Statements and footnotes thereto included in W-H's Annual
Report on Form 10-K/A for the year ended December 31, 2005 filed with the
Securities and Exchange Commission ("SEC"). In the opinion of management, all
necessary adjustments (which include only normal recurring adjustments)
considered necessary for a fair presentation have been included. Operating
results for the three and six months ended June 30, 2006 are not necessarily
indicative of the results that may be expected for the year ending December 31,
2006.

  ACCOUNTING POLICIES AND PROCEDURES

     Other than the adoption of Statement of Financial Accounting Standards
("SFAS") No. 123R "Share-Based Payment" ("SFAS No. 123R") as disclosed in Note
6, W-H has not added to or changed its accounting policies since December 31,
2005. For a description of these policies, refer to Note 2 of the Consolidated
Financial Statements in W-H's Annual Report on Form 10-K/A for the year ended
December 31, 2005.

     In June 2006, the Financial Accounting Standards Board issued FASB
Interpretation No. 48, "Accounting for Uncertainty in Income Taxes" ("FIN 48").
FIN 48 clarifies the application of SFAS No. 109, Accounting for Income Taxes,
by establishing a threshold condition that a tax position must meet for any part
of the benefit of that position to be recognized in the financial statements. In
addition to recognition, FIN 48 provides guidance concerning measurement,
derecognition, classification, and disclosure of tax positions. FIN 48 is
effective for fiscal years beginning after December 15, 2006; accordingly, W-H
will adopt FIN 48 effective as of January 1, 2007. W-H has not yet determined
the impact that FIN 48 will have on its consolidated financial statements or on
the effective tax rate in future years.

2.  EARNINGS PER SHARE

     Basic earnings per share excludes dilution and is computed by dividing net
income available to common shareholders by the weighted average number of shares
of common stock outstanding for the period. Diluted earnings per share is
computed considering the dilutive effect of stock options and nonvested
restricted shares. For the three months ended June 30, 2006 and 2005, 964,467
and 786,047 shares respectively, resulting from the assumed exercise of
outstanding stock options and outstanding nonvested restricted shares were added
to the denominator because the inclusion of such shares would be dilutive. For
the six months ended June 30, 2006 and 2005, 1,009,602 and 824,428 shares,
respectively, resulting from the assumed exercise of outstanding stock options
and outstanding nonvested restricted shares were added to the denominator
because the inclusion of such shares

would be dilutive. For the three months and six months ended June 30, 2006,
there were no anti-dilutive shares excluded from the computation of earnings per
share. For the three months and six months ended June 30, 2005, 92,000 shares
were excluded from the computation of earnings per share because the inclusion
of such shares would have been anti-dilutive.

4.  CREDIT FACILITY

     W-H maintains a revolving credit facility with certain lenders to provide
for its cash, liquidity and other borrowing needs. The credit facility provides
for aggregate borrowings of up to $375.0 million and matures on May 5, 2010. As
of June 30, 2006, W-H had an outstanding loan balance of $150.0 million and
approximately $8.0 million in letters of credit issued under its credit
facility, resulting in an available borrowing capacity on such date of
approximately $217.0 million.

     Amounts borrowed under the credit facility bear interest, at W-H's
election, at either a variable rate equal to LIBOR, plus a margin ranging from
1.0% to 2.0%, depending upon W-H's leverage ratio, or an alternate base rate
equal to the higher of (1) the prime rate or (2) the federal funds rate plus
0.5%, plus a margin ranging from zero to 1.0%, depending upon W-H's leverage
ratio. As of June 30, 2006, borrowings under the credit facility bore interest
at LIBOR plus the then applicable margin of 1.0%.

     In May 2005, W-H entered into interest rate swap agreements with a total
notional amount of $150.0 million related to its credit facility. Under these
agreements, W-H receives interest at a floating rate equal to three-month LIBOR
and pays interest at a fixed rate of 4.24%. The three-month LIBOR rate as of
June 30, 2006 was approximately 5.3%.

     The credit facility is secured by a lien on substantially all of W-H's
property and assets, a pledge of all the capital stock of W-H's domestic
subsidiaries and a pledge of not greater than 65% of the capital stock of each
of W-H's top tier foreign subsidiaries. In addition, the credit facility is
guaranteed by all of W-H's domestic subsidiaries. The credit facility requires,
among other things, that W-H maintain certain financial ratios, including a
leverage ratio and an interest coverage ratio, and a specified net worth. The
credit facility limits the amount of capital expenditures W-H may make, the
amount of debt W-H may incur outside of the credit facility, the amount of
future investments W-H may make, the ability of W-H to pay dividends and the
ability of W-H to engage in certain business combination transactions.

5.  LITIGATION

     W-H is from time to time a party or otherwise subject to legal proceedings,
claims, investigations and other proceedings in the ordinary course of its
business. These matters typically involve tort, workers compensation, commercial
and infringement and other intellectual property claims. Where appropriate, W-H
makes provision for a liability with respect to these claims in its financial
statements in accordance with generally accepted accounting principles. These
provisions are reviewed periodically and adjusted to reflect the impact of
negotiations,

                                        5

                            W-H ENERGY SERVICES, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

settlements, rulings, advice of legal counsel and events pertaining to a
particular case. Litigation is inherently unpredictable. Based upon information
currently available, management believes that the ultimate liability with
respect to these proceedings and claims will not materially affect W-H's
consolidated results of operations or financial position.

6.  SHARE-BASED COMPENSATION

     On May 10, 2006, W-H's shareholders approved the 2006 Stock Awards Plan
(the "2006 Plan"). Under the 2006 Plan, W-H may grant awards including stock
options, stock appreciation rights, restricted stock, restricted stock units,
performance units and other stock-based awards. An aggregate of 1,100,000 shares
of W-H's common stock are reserved for issuance under the plan, subject to
adjustments as described in the plan. The number of shares reserved for issuance
will be reduced only by the number of shares of common stock delivered in
payment or settlement of awards. Any shares of common stock issued in connection
with restricted stock, restricted stock units, performance units or other full
value awards will count against the limit of reserved shares as 1.7 shares of
common stock for every one share of common stock issued. Shares of common stock
issued in connection with other types of awards will be counted against the
limit of reserved shares as one share of common stock for every one share of
common stock issued. Each award granted under the 2006 Plan is subject to such
terms and conditions as the compensation committee of W-H's Board of Directors
may approve.

     W-H does not intend to grant stock options in the near term. In lieu of
stock option awards, W-H intends to award restricted stock and utilize a cash
incentive plan for senior management and other key employees.

     On May 31, 2006, W-H awarded a total of 117,000 shares of restricted stock
under the 2006 Plan to certain employees and directors. The restricted stock
vests ratably over a four-year period, commencing on the grant date, in 25%
increments after each year of service has been completed. The fair value of the
restricted stock issued was approximately $6.6 million, and is being recognized
as compensation expense over the four-year vesting period.

     Under the 2006 Plan, W-H is no longer permitted to issue new awards under
its 1997 Stock Option Plan (the "1997 Plan"). As of June 30, 2006, 1,712,179
stock options were outstanding under the 1997 Plan. The options currently
outstanding under the 1997 Option Plan vest ratably over a four-year period,
commencing on the grant date, in 25% increments after each year of service has
been completed, and will expire ten years from their respective grant dates. The
terms of each option also provide that if an optionee's employment terminates
for any reason, the option may be exercised during the three-month period
following such termination, but only to the extent vested at the time of such
termination.

     On March 29, 1999, prior to its initial public offering, W-H issued 900,900
options to its chief executive officer under a separate non-statutory option
plan. These options have a 10-year term and an exercise price of $4.55 per
share. As of June 30, 2006, the remaining unexercised options to purchase
445,000 shares of common stock were vested.

     Prior to January 1, 2006, W-H accounted for its stock-based compensation
under the recognition and measurement principles of Accounting Principles Board
("APB") Opinion No. 25, "Accounting for Stock Issued to Employees," and related
interpretations, the disclosure-only provisions of SFAS No. 123, "Accounting for
Stock-Based Compensation" and the disclosures required by SFAS No. 148,
"Accounting for Stock-Based Compensation-Transition and Disclosure." In
accordance with APB Opinion No. 25, no stock-based compensation cost was
reflected in W-H's net income for grants of stock options to employees because
W-H granted stock options with an exercise price equal to the market value of
its common stock on the date of grant. The reported stock-based compensation
expense, net of related tax effects, is disclosed in the table below and
represents the amortization of a restricted stock grant.

     If compensation expense for the stock options granted to employees and
directors had been determined using the fair value method, net income and
diluted net income per share for the three and six months ended June 30, 2005
would have been reduced to the following pro forma amounts:

     Effective January 1, 2006, W-H adopted the fair value recognition
provisions of SFAS No. 123R using the modified prospective method. Under this
method, compensation cost for the six months ended June 30, 2006 includes the
portion of any options vesting during the period for (1) all share-based
payments granted prior to, but not vested as of December 31, 2005, based on the
grant date fair value estimated in accordance with the original provisions of
SFAS No. 123 and (2) any share-based payments granted subsequent to December 31,
2005, based on the grant date fair value estimated using a binomial lattice-
based option valuation model. Before the adoption of SFAS No. 123R, pro forma
disclosures reflected the fair value of each option grant estimated on the date
of grant using the Black-Scholes option-pricing model. The following assumptions
were used for the historical option grants for the years ended December 31,
2005, 2004 and 2003: risk-free interest rates between 3.9% and 4.6%; dividend
rates of zero; expected lives between 5.6 years and 6.7 years; and expected
volatilities between 49.6% and 50.7%.

     Under the Black-Scholes option-pricing model, W-H estimated volatility
using only its historical share price performance over the expected life of the
option. Under SFAS No. 123R, however, W-H will estimate expected volatility
using a blend of implied volatility based on market-traded options on W-H's
common stock and historical volatility of W-H's common stock over the
contractual life of the options. Results of prior periods do not reflect any
restated amounts and W-H had no cumulative effect adjustment upon adoption of
SFAS No. 123R under the modified prospective method. For awards with service
conditions and a graded vesting schedule only, W-H recognizes compensation
expense on a straight-line basis over the requisite service period for the
entire award. W-H's policy is to issue new shares of common stock to satisfy
stock option exercises or grants of restricted shares.

     For the six months ended June 30, 2006, the adoption of SFAS No. 123R
decreased W-H's reported operating income and income before income taxes by
approximately $2.1 million, reported net income by $1.4 million and reported
basic and diluted net earnings per share by $0.05 per share. The share-based
compensation expense is reported in cost of revenues or selling, general and
administrative expense based on the classification of the optionees' cash
compensation expenses. The adoption of SFAS No. 123R resulted in a decrease in
reported cash flow from operating activities of $10.8 million offset by an
increase in reported cash flow from financing activities of $10.8 million for
the six months ended June 30, 2006. W-H's adoption of SFAS No. 123R did not
affect operating income, income before income taxes, net income, cash flow from
operations, cash flow from financing activities or basic and diluted net
earnings per share in the comparable 2005 period.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     The fair value of each option award will be estimated on the date of grant
using a binomial lattice-based option valuation model, which incorporates ranges
of assumptions for inputs. The assumptions will be determined as follows:

     - the expected volatility will be a blend of implied volatility based on
       market-traded options on W-H's common stock and historical volatility of
       W-H's stock over the contractual life of the options;

     - historical data will be used to estimate option exercise and employee
       termination behavior within the valuation model; separate groups of
       employees that have similar historical exercise behavior are considered
       separately for valuation purposes. The expected life of options granted
       will be derived from the output of the option valuation model and
       represents the period of time the options are expected to be outstanding;
       and

     - the risk-free interest rate will be based on the U.S. Treasury yield
       curve in effect at the time of grant for periods within the contractual
       life of the option.

     A summary of W-H's stock options from December 31, 2005 to June 30, 2006 is

7.  OPERATING SEGMENTS

     Management has elected to aggregate W-H's business unit segments based on
the differences in each segment's customers, the products and services offered
and other economic characteristics. Based on these criteria, management has
identified the following reportable segments: (1) drilling related products and
services and (2) completion and workover related products and services. The
accounting policies of the operating segments are the same as those described in
the summary of significant accounting policies in W-H's Annual Report on Form
10-K/A for the year ended December 31, 2005.

  DRILLING RELATED PRODUCTS AND SERVICES

     The drilling segment provides products and services used by oil and natural
gas companies, drilling contractors and other oilfield service companies for the
drilling of oil and natural gas wells. These products and services are used
primarily throughout North America and in select international areas. This
segment includes the following business lines: (1) logging-while-drilling; (2)
measurement-while-drilling; (3) directional drilling; (4) down-hole drilling
motors; (5) drilling fluids and (6) rental tools.

  COMPLETION AND WORKOVER RELATED PRODUCTS AND SERVICES

     The completion and workover segment provides products and services
primarily to customers onshore in the United States and offshore in the Gulf of
Mexico. These products and services include: (1) cased-hole wireline logging,
perforating, tubing conveyed perforating and associated rental equipment; (2)
coiled tubing; (3) polymers and specialty chemicals and (4) rental tools.

  SUMMARY INFORMATION

     W-H recognizes revenues, operating income, depreciation and amortization
expense, total assets and capital expenditures by segment. Interest expense and

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

FORWARD-LOOKING STATEMENTS

     In addition to historical information, this report contains forward-looking
statements within the meaning of Section 27A of the Securities Act of 1933 and
Section 21E of the Securities Exchange Act of 1934 that involve risks,
uncertainties and assumptions. The words "believe," "expect," "plan," "intend,"
"estimate," "project," "will," "could," "may," and similar expressions are
intended to identify forward-looking statements. Actual results may differ
materially from the results discussed in the forward-looking statements as a
result of important risk factors including, but not limited to, trends in oil
and natural gas prices, capital expenditures by customers, oil and natural gas
industry activity, difficulty in continuing to develop, produce and
commercialize technologically advanced products and services, weather conditions
in offshore and land markets, risks associated with events that result in
personal injuries, loss of life, damage to or destruction of property, equipment
or the environment and suspension of operations, unavailability of or costs
associated with insurance, our ability to attract and retain skilled workers,
the loss of key members of management, competition in our industry, compliance
with and developments in environmental and other governmental regulations, loss
of use of certain technologies, the concentration of customers in the energy
industry, our ability to successfully integrate future acquisitions, political
and economic risks including changes in tax laws, an impairment of goodwill, as
well as restrictions on our ability to raise additional funds. For additional
discussion of these risks, please see the discussion set forth under the heading
"Item 1A -- Risk Factors" contained in our most recent Annual Report filed on
Form 10-K with the Securities and Exchange Commission ("SEC").

OVERVIEW OF OUR PRODUCTS AND SERVICES

     We provide drilling related products and services and completion and
workover related products and services to major and independent oil and natural
gas companies, drilling contractors and other oilfield service companies. The
majority of our revenues are generated from charging our customers day rates,
based on the number of days our products and services are used. We also sell
certain products used in the exploration for and production of oil and natural
gas and receive revenues from our customers in connection with these sales. Our
primary expenses are salaries for our personnel and the costs associated with
expendable parts and supplies, research and development, repair and maintenance
of rental equipment and costs of products sold as well as general operational
costs. As a result of increased demand and competition for skilled personnel,
compensation costs to attract and retain employees have been increasing.

     Prices for oil and natural gas are subject to large fluctuations in
response to relatively minor changes in the supply of and demand for oil and
natural gas, market uncertainty and a variety of other factors. Any prolonged
increase or decrease in oil and natural gas prices affects the levels of
exploration, development and production activity as well as the entire health of
the oil and natural gas industry. Demand for our drilling related products and
services is directly affected by the level of exploration, development and
production activity of, and the corresponding capital spending by, oil and
natural gas companies. Demand for our completion and workover related products
and services depends more on oil and natural gas production activity, which is
less immediately affected by changes in oil and natural gas prices.

     In July 2001, exploration and development activity levels in the United
States peaked and subsequently began to decline primarily as a result of lower
natural gas prices. This decline continued through April 2002, at which point
the United States drilling rig count levels reached a low of 738, which
consisted of 110 offshore rigs and 628 land rigs. As natural gas prices climbed
and remained relatively strong, rig count levels began to recover in 2003 and
this trend has continued through the first half of 2006. This increase, however,
resulted almost entirely from an increase in land-based rigs. According to
statistics published by Baker Hughes, the average number of rotary rigs
operating in the United States was 1,192, 1,383 and 1,578 for 2004, 2005 and the
first six months of 2006, respectively. Of these figures, land rigs comprised
1,095, 1,290 and 1,489, respectively, and offshore rigs comprised 97, 93 and 89,
respectively, for the same periods. The offshore rig count did improve during
the second quarter of 2006 but remains well below the previous peak levels of
2001.

     We believe that the overall long-term outlook for domestic natural gas
exploration and development activity remains positive. First, despite
significant increases in drilling activity in 2005 and through the first half of
2006, natural gas production, excluding the impact of Hurricanes Katrina and
Rita, has increased only nominally. Second,

                                       11

<PAGE>

industrial gas consumption, electric power generation, and a healthy economy
continue to drive domestic natural gas demand. We believe that these factors
will keep upward pressure on long-term natural gas prices. In addition, we have
seen a consolidation in the ownership of Gulf of Mexico oil and natural gas
reserves to companies who have a more aggressive approach to developing these
reserves. We do have a concern that the current high storage levels of natural
gas, which primarily resulted from the relatively mild winter in 2005-2006,
could negatively impact natural gas prices in the near term. This may result in
a slowdown in natural gas drilling or production activity or both. As of early
August 2006, the relatively hot weather throughout most of the United States is
helping to offset the high storage levels of natural gas and natural gas
drilling and production activities remain strong. We believe any slowdown that
may occur would be short-lived as long as the positive factors set forth above
affecting long-term supply and demand remain in place.

     Outside of the United States, the North Sea remains our largest drilling
segment market. According to statistics published by Baker Hughes, the number of
rotary rigs operating in the North Sea declined from an average of 67 in January
2002 to a low of 28 in February 2005, before recovering to an average of 54 in
June 2006. We expect no significant change in activity levels in the North Sea
in the near term.

  DRILLING RELATED PRODUCTS AND SERVICES

     Revenue from our drilling related products and services segment provided
approximately 63% of our consolidated revenue for the six months ended June 30,
2006. Approximately 84% of our drilling segment revenue for this period was
generated in the United States, including the Gulf of Mexico. The remaining 16%
was generated in various international locations.

     As the improvement in drilling activity in the United States has been
onshore, we have sought to increase the content of our land-based services. In
October 2002, in response to this developing trend, we made the strategic
decision to enter the directional drilling business in North America. As a
result of this decision and the growth in the United States land rig count, we
have successfully leveraged our new directional drilling business to effect an
increase in the utilization of our measurement-while-drilling tools and down-
hole drilling motor fleet. The increased utilization of our measurement-while-
drilling tools and down-hole drilling motor fleet has helped to offset the
slowdown in domestic offshore activity. However, our logging-while-drilling
revenues from the offshore market have outperformed the rig count numbers as a
result of performing more jobs with a higher content of our services, improved
prices and an increase in our share of this market.

     A key challenge that our drilling related products and services segment
faces is the demand by our customers for more efficient and technologically
advanced services and tools. We have invested substantial time and capital into
developing and commercializing technologies that are of value to our customers
and that enable us to compete effectively with the major integrated oilfield
service companies. During the third quarter of 2004, we began to market our
PathMaker(R) 12 1/4" 3-Dimensional Rotary Steerable technology. We expect
commercialization of the 3-Dimensional Rotary Steerable technology to improve
the utilization of our logging-while-drilling, measurement-while-drilling and
directional drilling services, as our customers are increasingly requiring this
type of technology as a prerequisite for submitting bids on a drilling project
or contract. We are currently developing a PathMaker(R) 8 1/2" 3-Dimensional
Rotary Steerable tool and began offering this tool on a limited commercial basis
during the first quarter of 2006.

     Introduced on a commercial basis in late 2004, our Array Wave Resistivity
technology is the first of our next generation of logging-while-drilling tools.
We believe that our Array Wave Resistivity tools provide a more robust and
accurate resistivity measurement. Tools and data analysis in this technology
improve the precision and reliability of formation data obtained through the
analysis of electromagnetic wave transmissions through the formation surrounding
a well bore. Our Array Wave Resistivity tools are also designed to withstand
high pressure (25,000 psi) and high temperature (350 degrees F) well conditions.

  COMPLETION AND WORKOVER RELATED PRODUCTS AND SERVICES

     Our completion and workover related products and services segment provided
approximately 37% of our consolidated revenue for the six months ended June 30,
2006. Revenues provided by this segment are almost entirely derived from the
United States and the Gulf of Mexico. While revenues from this segment are
affected by

                                       12

<PAGE>

the level of oil and natural gas prices, activity in this segment is only
modestly affected by drilling activity as discussed above. As a result, our
completion and workover related products and services segment has provided
stability during prolonged downturns in drilling activity.

     In response to the increase in land-based activity, we increased our
revenue capacity in this segment through acquisitions in 2002 and 2003. Since
that time, we have organically grown in these markets through capital spending,
which, when combined with our acquisitions, has strengthened and further
diversified our operations. Presently, we continue to grow our existing
operations and expand our geographic reach, particularly in areas of large
unconventional natural gas reserves. Continued growth in this segment will be
dependent upon, among other factors, industry activity levels, prices of oil and
natural gas, our capital expenditure program and our ability to attract and
retain qualified service personnel and field engineers required to operate the
specialized equipment used in this business.

RESULTS OF OPERATIONS

     The following information should be read in conjunction with our
Consolidated Financial Statements and the accompanying notes presented elsewhere
in this Form 10-Q.

  THREE MONTHS ENDED JUNE 30, 2006 COMPARED TO THE THREE MONTHS ENDED JUNE 30,
  2005

     Revenues.  Revenues increased by $58.5 million, or approximately 37%, to
$215.8 million for the three months ended June 30, 2006 from $157.3 million for
the three months ended June 30, 2005. This increase was primarily attributable
to higher levels of activity and demand for certain of our products and
services, additional revenue capacity from our capital expenditure investments,
and favorable pricing.

     Revenues from our drilling related products and services increased by $33.9
million, or approximately 34%, to $134.6 million for the three months ended June
30, 2006 from $100.7 million for the three months ended June 30, 2005. We
attribute the increase in revenues in this segment to:

     - a 22% increase in the average number of rotary rigs operating in the
       United States, resulting in an increase in demand for our directional
       drilling services and technologically advanced services and tools, rental
       tools and drilling fluids products;

     - our larger asset base resulting from our capital expenditure investments;

     - improved pricing; and

     - an increase in our Gulf of Mexico market share, resulting from higher
       utilization of our existing logging-while-drilling tools and
       commercialization of certain of our new technologies discussed earlier.

     Revenues from our completion and workover related products and services
increased by $24.5 million, or approximately 43%, to $81.1 million for the three
months ended June 30, 2006 from $56.6 million for the three months ended June
30, 2005. We attribute the increase in revenues in this segment to:

     - higher demand for our tools and services as a result of an overall
       increase in activity levels;

     - an increase in our cased-hole wireline and coiled tubing fleets and other
       capital expenditure investments;

     - improved pricing; and

     - onshore geographic expansion.

     Cost of Revenues.  Cost of revenues increased by $25.0 million, or
approximately 28%, to $112.8 million for the three months ended June 30, 2006
from $87.8 million for the three months ended June 30, 2005. As a percentage of
revenues, cost of revenues decreased to 52% for the three months ended June 30,
2006 from 56% for the three months ended June 30, 2005. The decrease in cost of
revenues as a percentage of revenues was primarily due to a change in our
revenue mix, improved utilization in both business segments and higher pricing.
In particular, our revenue mix was affected by revenue increases in our higher
margin logging-while-drilling, measurement-while-drilling, directional drilling
and coiled tubing operations. These margin improvements were partially offset by
higher employee compensation expenses and other operational costs.


                                       13

<PAGE>

     Selling, General and Administrative Expenses.  Selling, general and
administrative expenses increased by $10.0 million, or approximately 36%, to
$37.5 million for the three months ended June 30, 2006 from $27.5 million for
the three months ended June 30, 2005. The increase was primarily attributable to
increased selling costs attributable to our revenue growth and other personnel
costs related to expansion efforts within all of our business lines. As a
percentage of revenues, selling, general and administrative expenses was 17% for
each of the three-month periods ended June 30, 2006 and 2005.

     Warehouse Fire Related Costs.  On April 17, 2005, a Houston warehouse
facility operated by one of our subsidiaries was destroyed by a fire. For the
three months ended June 30, 2005, we reported $3.7 million in costs associated
with this fire, net of anticipated insurance reimbursements. This amount has
been reflected in the Consolidated Statements of Operations and Comprehensive
Income under the caption "Warehouse fire related costs" and as a reduction to
operating income for the drilling segment in Footnote 7 "Operating Segments" for
the three-month and six-month periods ended June 30, 2005.

     Research and Development Expenses.  Research and development expenses
decreased by $0.5 million, or approximately 11%, to $4.0 million for the three
months ended June 30, 2006 from $4.5 million for the three months ended June 30,
2005. This decrease was the result of a higher rate of research and development
spending in the corresponding period in 2005 on our PathFinder Energy Services,
Inc. technologies, including our PathMaker(R) 8 1/2" 3-Dimensional Rotary
Steerable tool.

     Depreciation and Amortization.  Depreciation and amortization increased by
$1.3 million, or approximately 9%, to $15.3 million for the three months ended
June 30, 2006 from $14.0 million for the three months ended June 30, 2005. This
increase was the result of a larger depreciable asset base resulting from our
capital expenditure investments.

     Interest and Other Expense.  Interest and other expense for the three
months ended June 30, 2006 was $2.3 million, a decrease of $0.6 million, or
approximately 21%, from $2.9 million for the three months ended June 30, 2005.
This decrease was primarily due to decreased interest expense due to lower
outstanding borrowings under our credit facility.

     Provision for Income Taxes.  Our effective income tax rate for the three
months ended June 30, 2006 was 36% as compared to 33% for the three months ended
June 30, 2005. The 2006 period included a non-recurring tax benefit of
approximately $0.9 million related to the write-off of deferred tax liabilities
due to a new tax law enacted in Texas during the period. The increase in the
2006 effective rate compared to 2005 was due to several factors including, but
not limited to, a tax benefit in the 2005 period related to settlement of a
foreign tax audit, and fluctuations in income across tax jurisdictions with
varying tax rates. We anticipate that the effective income tax rate for the
remainder of 2006 will range from 38% to 39% assuming no additional discrete tax
items. Beginning in 2007, the tax law change in Texas is expected to increase
our overall effective tax rate.

  SIX MONTHS ENDED JUNE 30, 2006 COMPARED TO THE SIX MONTHS ENDED JUNE 30, 2005

     Revenues.  Revenues increased by $117.9 million, or approximately 39%, to
$417.6 million for the six months ended June 30, 2006 from $299.7 million for
the six months ended June 30, 2005. This increase was primarily attributable to
higher levels of activity and demand for certain of our products and services,
additional revenue capacity from our capital expenditure investments, and
favorable pricing.

     Revenues from our drilling related products and services increased by $71.2
million, or approximately 37%, to $263.7 million for the six months ended June
30, 2006 from $192.5 million for the six months ended June 30, 2005. We
attribute the increase in revenues in this segment to:

     - a 20% increase in the average number of rotary rigs operating in the
       United States, resulting in an increase in demand for our directional
       drilling services and technologically advanced services and tools, rental
       tools and drilling fluids products;

     - our larger asset base resulting from our capital expenditure investments;

     - improved pricing; and


                                       14

<PAGE>

     - an increase in our Gulf of Mexico market share, resulting from higher
       utilization of our existing logging-while-drilling tools and
       commercialization of certain of our new technologies discussed earlier.

     Revenues from our completion and workover related products and services
increased by $46.7 million, or approximately 44%, to $153.9 million for the six
months ended June 30, 2006 from $107.2 million for the six months ended June 30,
2005. We attribute the increase in revenues in this segment to:

     - higher demand for our tools and services as a result of an overall
       increase in activity levels;

     - an increase in our cased-hole wireline and coiled tubing fleets and other
       capital expenditure investments;

     - improved pricing; and

     - onshore geographic expansion.

     Cost of Revenues.  Cost of revenues increased by $52.0 million, or
approximately 31%, to $220.8 million for the six months ended June 30, 2006 from
$168.8 million for the six months ended June 30, 2005. As a percentage of
revenues, cost of revenues decreased to 53% for the six months ended June 30,
2006 from 56% for the six months ended June 30, 2005. The decrease in cost of
revenues as a percentage of revenues was primarily due to a change in our
revenue mix in our drilling related products and services, improved utilization
in both business segments and higher pricing. In particular, our revenue mix was
affected by revenue increases in our higher margin logging-while-drilling,
measurement-while-drilling, directional drilling and coiled tubing operations.
These margin improvements were partially offset by higher employee compensation
expenses and other operational costs.

     Selling, General and Administrative Expenses.  Selling, general and
administrative expenses increased by $18.6 million, or approximately 35%, to
$72.0 million for the six months ended June 30, 2006 from $53.4 million for the
six months ended June 30, 2005. The increase was primarily attributable to
increased selling costs attributable to our revenue growth and other personnel
costs related to expansion efforts within all of our business lines. As a
percentage of revenues, selling, general and administrative expenses decreased
to 17% for the six months ended June 30, 2006 from 18% for the six months ended
June 30, 2005.

     Warehouse Fire Related Costs.  On April 17, 2005, a Houston warehouse
facility operated by one of our subsidiaries was destroyed by a fire. For the
six months ended June 30, 2005, we reported $3.7 million in costs associated
with this fire, net of anticipated insurance reimbursements. This amount has
been reflected in the Consolidated Statements of Operations and Comprehensive
Income under the caption "Warehouse fire related costs" and as a reduction to
operating income for the drilling segment in Footnote 7 "Operating Segments" for
the three-month and six-month periods ended June 30, 2005.

     Research and Development Expenses.  Research and development expenses
decreased by $1.5 million, or approximately 16%, to $7.8 million for the six
months ended June 30, 2006 from $9.3 million for the six months ended June 30,
2005. This decrease was the result of a higher rate of research and development
spending in the corresponding period in 2005 on our PathFinder Energy Services,
Inc. technologies, including our PathMaker(R) 8 1/2" 3-Dimensional Rotary
Steerable tool.

     Depreciation and Amortization.  Depreciation and amortization increased by
$2.5 million, or approximately 9%, to $30.3 million for the six months ended
June 30, 2006 from $27.8 million for the six months ended June 30, 2005. This
increase was the result of a larger depreciable asset base resulting from our
capital expenditure investments.

     Interest and Other Expense.  Interest and other expense for the six months
ended June 30, 2006 was $4.5 million, a decrease of $0.8 million, or
approximately 15%, from $5.3 million for the six months ended June 30, 2005.
This decrease was primarily due to lower outstanding borrowings under our credit
facility offset, in part, by higher interest rates.

     Provision for Income Taxes.  Our effective income tax rate for the six-
month periods ended June 30, 2006 and 2005 was 37%. The 2006 period included a
non-recurring tax benefit of approximately $0.9 million related to the write-off
of deferred tax liabilities due to a new tax law enacted in Texas during the
period. The 2005 period included a tax benefit related to settlement of a
foreign tax audit. We anticipate that the effective income tax rate for

                                       15

<PAGE>

the remainder of 2006 will range from 38% to 39% assuming no additional discrete
tax items. Beginning in 2007, the tax law change in Texas is expected to
increase our overall effective tax rate.

RECENT ACCOUNTING PRONOUNCEMENTS

     We adopted Statement of Financial Accounting Standards No. 123R, "Share-
Based Payment," ("SFAS No. 123R") as of January 1, 2006 using the modified
prospective method in which compensation cost is recognized based (1) on the
requirements of SFAS No. 123R for all share-based payments granted after January
1, 2006 and (2) on the requirements of SFAS No. 123 for all awards granted to
employees prior to January 1, 2006 that remain unvested on January 1, 2006. For
the six months ended June 30, 2006, we recorded approximately $2.1 million of
pretax expense relating to this pronouncement for nonvested share-based payments
granted prior to January 1, 2006. The Compensation Committee of our Board of
Directors may award additional stock options during 2006 which would increase
the amount of this expense prospectively. See Note 6 to the Consolidated
Financial Statements for additional information.

     In June 2006, the Financial Accounting Standards Board issued FASB
Interpretation No. 48, "Accounting for Uncertainty in Income Taxes" ("FIN 48").
FIN 48 clarifies the application of SFAS No. 109, Accounting for Income Taxes,
by establishing a threshold condition that a tax position must meet for any part
of the benefit of that position to be recognized in the financial statements. In
addition to recognition, FIN 48 provides guidance concerning measurement,
derecognition, classification, and disclosure of tax positions. FIN 48 is
effective for fiscal years beginning after December 15, 2006; accordingly, we
will adopt FIN 48 effective as of January 1, 2007. We have not yet determined
the impact that FIN 48 will have on our consolidated financial statements or on
the effective tax rate in future years.

LIQUIDITY AND CAPITAL RESOURCES

     Our primary uses for cash are capital expenditures, working capital,
research and development expenditures, acquisitions and principal and interest
payments on indebtedness. Our primary sources of liquidity are cash reserves,
cash generated by operations and amounts available to be drawn under our
revolving credit facility. To the extent our cash requirements exceed our
sources of liquidity, we will be required to fund our cash requirements through
other means, such as through debt and equity financing activities, or we will be
required to curtail our expenditures.

  CASH FLOW

     Working capital was $199.3 million as of June 30, 2006 and $160.1 million
as of December 31, 2005. Net cash provided by operating activities was $44.3
million for the six months ended June 30, 2006 and $34.1 million for the six
months ended June 30, 2005. The increase in working capital and cash flow from
operating activities was largely due to increases in activity levels across all
business lines.

     Net cash used in investing activities was $48.5 million for the six months
ended June 30, 2006 and $44.5 million for the six months ended June 30, 2005.
The increase in net cash used in investing activities was the result of
increased capital expenditures which was partially offset by an increase in
proceeds from sales of equipment which are primarily lost-in-hole proceeds we
receive from a customer when our rental equipment is involuntarily damaged or
lost-in-hole.

     Net cash provided by financing activities was $11.0 million for the six
months ended June 30, 2006 and $10.8 million for the six months ended June 30,
2005. Changes in net cash related to financing activities were primarily the
result of net repayments of borrowings under our credit facility in the 2006
period compared to net borrowings under our credit facility in the 2005 period.
Additionally, the 2006 period included significantly higher proceeds from the
exercise of stock options and the related tax benefits.

     For the six months ended June 30, 2006, we made capital expenditures,
primarily for rental equipment of $63.5 million, which included expenditures for
the replacement of rental equipment including rental tools damaged or lost-in-
hole. In addition, we incurred $4.0 million in research and development expenses
for the six months ended June 30, 2006.

  CAPITAL RESOURCES

  Credit Agreement

     As more fully described under Item 1, Note 4, we maintain a revolving
credit facility to provide for our cash, liquidity and other borrowing needs.
This credit facility provides for aggregate borrowings of up to $375 million and
matures on May 5, 2010. As of June 30, 2006, we had an outstanding loan balance
of $150.0 million and approximately $8.0 million in letters of credit issued
under our credit facility, resulting in available borrowing capacity on such
date of approximately $217.0 million.

  Future capital requirements

     We anticipate that acquisitions of complementary companies, assets and
product lines will continue to play an important role in our business strategy.
While there are currently no unannounced agreements or ongoing negotiations for
the acquisition of any material businesses or assets, such transactions can be
effected quickly and may occur at any time. Likewise, we will continue to need
to make capital expenditures for rental equipment and to make research and
development expenditures to maintain and improve the quality of our products and
services. We currently estimate that we will make capital expenditures of
approximately $150.0 million in 2006 and will make research and development
expenditures of approximately $18.0 million in 2006.

     We believe that our internally generated cash flow combined with access to
our credit facility will be sufficient to meet the liquidity requirements
necessary to fund our operations, capital expenditures, research and development
and debt service requirements for at least the next 12 months. However, our
ability to maintain our credit facility and the sufficiency of our internally
generated cash flow can be impacted by economic conditions outside of our
control.

     The continuation of our acquisition strategy may require substantial
capital. We currently intend to finance future acquisitions through issuances of
our equity or debt securities, cash on hand and through borrowings under our
credit facility. Using debt to complete acquisitions could substantially limit
our operational and financial flexibility and using equity could dilute the
ownership interests of our existing shareholders. The extent to which we will be
able or are willing to use our common stock to make acquisitions will depend on
its market value from time to time and the willingness of potential sellers to
accept it as full or partial payment. If we are unable to obtain additional
capital on acceptable terms, we may be unable to grow through acquisitions.

  Off balance sheet arrangements

     With the exception of operating leases on real property and automobile
leases, we have no off-balance sheet debt or other off-balance sheet financing
arrangements.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     We are exposed to market risks. Market risk is the potential loss arising
from adverse changes in market prices and rates. We have not entered into
derivative or other financial instruments for trading or speculative purposes.
Our market risk could arise from changes in interest rates and foreign currency
exchange rates.

     Interest Rate Risk.  We are subject to market risk exposure related to
changes in interest rates. To manage this risk, we have entered into interest
rate swap agreements with a total notional amount of $150.0 million related to
our credit facility. Under these agreements, we receive interest at a floating
rate equal to three-month LIBOR and pay interest at a fixed rate of 4.24%. The
three-month LIBOR rate as of June 30, 2006 was approximately 5.3%. Assuming our
current level of borrowings and considering the effect of the interest rate swap
agreements, a 100 basis point increase in the interest rate we pay under our
credit facility would have had no impact on our net interest expense for the six
months ended June 30, 2006.

     Foreign Currency Exchange Risk.  Our earnings and financial position are
affected by foreign exchange rate fluctuations. We currently do not hedge
against foreign currency translation risks and we believe that foreign currency
exchange risk is unlikely to be significant to our operations.

     Stock Price Volatility.  Our ability to raise capital at a reasonable cost
of capital is, in part, affected by the market price of our common stock. The
market price of our common stock may be influenced by many factors

                                       17

<PAGE>

including variations in our earnings, variations in oil and natural gas prices,
the level of exploration, development and production activity of, and the
corresponding capital spending by, our customers, investor perceptions of us and
other oilfield service companies and the liquidity of the market for our common
stock.

ITEM 4.  CONTROLS AND PROCEDURES

     Disclosure Controls and Procedures.  We maintain disclosure controls and
procedures, which are controls and procedures designed to ensure that the
information we are required to disclose in the reports we file with the SEC is
recorded, processed, summarized and reported within the time periods specified
in the rules and forms of the SEC. Based on an evaluation of our disclosure
controls and procedures as of the end of the period covered by this report
conducted by our management, with the participation of our Chief Executive
Officer and Chief Financial Officer, our Chief Executive Officer and Chief
Financial Officer believe that these controls and procedures are effective to
provide reasonable assurance that we are able to collect, process and disclose
the information we are required to disclose in the reports we file with the SEC
within the required time periods.

     Internal Control over Financial Reporting.  During the period covered by
this report, there were no changes in our internal control over financial
reporting that have materially affected or are reasonably likely to materially
affect our internal control over financial reporting.

     Our management, including our Chief Executive Officer and Chief Financial
Officer, does not expect that our disclosure controls and procedures or our
internal control over financial reporting will prevent and/or detect all error
and all fraud. A control system, no matter how well conceived and operated, can
provide only reasonable, not absolute, assurance that the objectives of the
control system are met. Further, the design of a control system must reflect the
fact that there are resource constraints, and the benefits of controls must be
considered relative to their costs. Because of the inherent limitations in all
control systems, no evaluation of controls can provide absolute assurance that
all control issues and instances of fraud, if any, within our company have been
detected.

                                OTHER INFORMATION

ITEM 2.  UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

     On July 24, 2006, one of our subsidiaries acquired Mt. Pulaski Products,
Inc. and related companies from three individuals for consideration consisting
of $9.4 million in cash and 20,358 shares of our common stock. Such common stock
issuance constituted a private placent that was exempt from the registration
requirements of Section 5 of the Securities Act of 1933 pursuant to Section 4(2)
of such act and pursuant to Regulation D thereunder. No underwriters
participated in such issuance.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     The 2006 annual meeting of the shareholders of the Company was held was
held on May 10, 2006. The purpose of the meeting was to elect members of our
Board of Directors and approve our 2006 Stock Awards Plan.

     At the annual meeting, each of the directors nominated by our Board of
Directors to serve a one-year term until the 2007 annual meeting of shareholders
was re-elected (there were no broker non-votes):
