         OIL STATES ANNOUNCES FOURTH QUARTER EARNINGS OF $0.98 PER SHARE

    HOUSTON, Feb. 7 /PRNewswire-FirstCall/ -- Oil States International, Inc.
(NYSE: OIS) today reported net income for the quarter ended December 31, 2006 of
$49.4 million, or $0.98 per diluted share. These results compare to $41.4
million, or $0.82 per diluted share, reported in the fourth quarter of 2005.
With strong contributions from its Well Site Services and Offshore Products
groups, Oil States recognized year-over-year growth in revenues and EBITDA
(defined as net income plus interest, taxes, depreciation and amortization) of
8% and 25%, respectively, in the fourth quarter of 2006.[A]

    The Company generated $484.3 million of revenues and $90.4 million of EBITDA
in the fourth quarter of 2006 compared to $447.1 million and $72.4 million,
respectively, in the fourth quarter of 2005. Improvements in Offshore Products'
revenues and EBITDA coupled with significant year-over-year increases in Well
Site Services EBITDA contributed to the strong fourth quarter results. Well Site
Services reported greater revenues and EBITDA due to continuing high levels of
North American drilling activity, capital investments made in the past year and
contributions from oil sands related accommodations. Offshore Products generated
significantly improved revenues and EBITDA due to increased deepwater
development spending and capital equipment upgrades by its customers. Offshore
Products' backlog increased 9% during the quarter to a record $349.3 million.
Tubular Services reported essentially flat revenues, but EBITDA declined
compared to the prior year because of lower gross margins realized. Corporate
and Other expenses increased $2.3 million in the fourth quarter of 2006 compared
to the prior year's fourth quarter primarily due to increased stock award
expense related to the adoption of SFAS 123R in 2006. The Company's effective
tax rate was 31.3% in the current quarter compared to 24.8% in the fourth
quarter of last year. The effective tax rate in the fourth quarter of 2006 was
lower than expected because of tax return adjustments and the annualized benefit
of lower state effective tax rates. The effective tax rate in the fourth quarter
of 2005 included a $4.6 million, or $0.09 per diluted share, income tax benefit
related to the reversal of substantially all of the Company's remaining
valuation allowances applied against net operating loss carryforwards. During
the fourth quarter of 2006, the Company repurchased 300,000 shares of its common
stock (at an average price of $32.92 per share) under its current share
repurchase program and spent $25.0 million in capital expenditures. As of
December 31, 2006, the Company's debt to total capitalization ratio was 32.2%.

    For the year ended December 31, 2006, the Company reported record net income
of $197.6 million, or $3.89 per diluted share, on revenues of $1.9 billion and
EBITDA of $372.9 million. For the year ended December 31, 2005, the Company
reported net income of $121.8 million, or $2.41 per diluted share, on revenues
of $1.5 billion and EBITDA of $242.6 million. This performance represents
year-over-year revenue and EBITDA increases of 26% and 54%, respectively. Net
income in 2006 included the recognition in the first quarter of a non-cash,
pre-tax gain of $11.3 million, or an after-tax gain of $0.12 per diluted share,
on the sale of the Company's workover services business to Boots & Coots
International Well Control, Inc. Capital expenditures for the year totaled
$129.1 million, a substantial portion of which was spent on expanding our
accommodations fleet in support of construction activity in the oil sands region
of Canada.

    BUSINESS SEGMENT RESULTS

    (Unless otherwise noted, the following discussion compares the results from
the fourth quarter of 2006 to the results from the fourth quarter of 2005.)



    Well Site Services

    Well Site Services generated improved fourth quarter results due to a 16%
year-over-year increase in the U.S. drilling rig count and contributions from
$117.4 million of capital investments made over the past year, partially offset
by a 23% decrease in the Canadian drilling rig count and the sale of the
hydraulic workover business completed in the first quarter of 2006. For the
fourth quarter of 2006, Well Site Services generated revenues of $158.5 million
and EBITDA of $62.9 million compared to $152.8 million and $40.4 million,
respectively, in the fourth quarter of 2005. Higher revenues and margins in
drilling services and rental tools contributed to the segment's 4%
year-over-year increase in revenues and 56% increase in EBITDA. This growth in
revenues and EBITDA was partially offset by the conversion of the Company's
investment in its workover services business (which accounted for $10.2 million
in revenues and $2.6 million in EBITDA in the fourth quarter of 2005) to equity
accounting with the sale of the business to Boots & Coots in March 2006.

    For the fourth quarter of 2006, the accommodations business generated $70.4
million of revenues and $23.3 million of EBITDA compared to $72.0 million and
$10.5 million, respectively, in the fourth quarter of 2005. Year-over-year
quarterly revenues were down slightly due to lower traditional drilling camp
activity and decreased third-party manufacturing work, partially offset by
increased oil sands related activity. Accommodations' EBITDA grew dramatically
year-over-year, as did the EBITDA margin percentage, due primarily to increased
contributions from higher margin rental and catering services in support of oil
sands developments. The Accommodations results for the fourth quarter of 2005
included significant revenues at lower margins related to a large third party
manufacturing contract which has since been completed. Rental Tools generated a
14% year-over-year increase in revenues and a 21% increase in EBITDA primarily
due to contributions from capital expenditures made over the past year,
partially offset by weaker completion activity in Canada. Drilling and Other
generated revenues and EBITDA of $37.2 million and $19.7 million, respectively,
in the fourth quarter of 2006 compared to $26.1 million of revenues and $10.9
million of EBITDA in the fourth quarter 2005 due to improved pricing, contract
terms, rig fleet expansion and the inclusion of equity in earnings from the
Company's investment in Boots & Coots (which only impacted EBITDA).

    Offshore Products

    During the fourth quarter of 2006, Offshore Products generated $107.7
million of revenues and $17.1 million in EBITDA compared to $76.5 million and
$12.4 million, respectively, in the fourth quarter of 2005. Gross margin
percentage for the fourth quarter declined to 23% from 25% in the fourth quarter
of 2005. The lower gross margin was primarily due to product mix and cost
absorption. For the fourth consecutive quarter, backlog reached a record level
totaling $349.3 million at December 31, 2006 compared to $321.2 million at
September 30, 2006 and $110.7 million as of December 31, 2005.

    Tubular Services

    Tubular Services reported revenues of $218.1 million and EBITDA of $15.6
million for the fourth quarter of 2006 compared to $217.8 million and $22.5
million, respectively, in the fourth quarter of 2005. Tubular Services' OCTG
shipments of 118,400 tons during the fourth quarter were essentially flat with
2005. Gross margins in the fourth quarter of 2006 declined to 8.5% from 11.0% in
the fourth quarter of 2005 because of relatively flat OCTG mill pricing
throughout most of 2006 and competitor destocking during the fourth quarter. The
Company's OCTG inventory as of December 31, 2006 was $261.8 million compared to
$279.9 million at September 30, 2006 and $274.2 million as of December 31, 2005.
As of December 31, 2006, approximately 66% of Oil States' OCTG inventory was
committed to customer orders.

    "Oil States finished 2006 with a record year of profitability," stated
Douglas E. Swanson, Oil States' Chief Executive Officer. "U.S. drilling and
completion activity remained at a high level despite concerns about high natural
gas storage levels and reduced natural gas pricing.



We experienced some weakness in Canada in the fourth quarter of 2006 and into
the first quarter of 2007 due to warmer weather and lower natural gas prices.
However, this weakness is mitigated to a large degree by growth in Offshore
Products and our activities that are tied to the oil sands developments. As
evidenced by our recently announced capital spending commitments, we believe
that the oil sands region of Canada continues to provide significant
opportunities for organic growth in our Accommodations business going forward.
Our current expectation for first quarter 2007 earnings is in a range of $0.97
to $1.02 per diluted share."

[A]  The term EBITDA consists of net income plus interest, taxes,
     depreciation and amortization. EBITDA is not a measure of financial
     performance under generally accepted accounting principles. You should not
     consider it in isolation from or as a substitute for net income or cash
     flow measures prepared in accordance with generally accepted accounting
     principles or as a measure of profitability or liquidity. Additionally,
     EBITDA may not be comparable to other similarly titled measures of other
     companies. The Company has included EBITDA as a supplemental disclosure
     because its management believes that EBITDA provides useful information
     regarding our ability to service debt and to fund capital expenditures and
     provides investors a helpful measure for comparing its operating
     performance with the performance of other companies that have different
     financing and capital structures or tax rates. The Company uses EBITDA to
     compare and to monitor the performance of its business segments to other
     comparable public companies and as a benchmark for the award of incentive
     compensation under its annual incentive compensation plan.

[B]  As of December 31, 2006, the Company had approximately $173.9 million
     available under its revolving credit facility.

[C]  On March 1, the Company sold the workover services business to Boots &
     Coots International Well Control, Inc. for equity and debt consideration.
     Subsequent to closing, Drilling and Other results include equity in
     earnings of unconsolidated affiliates related to this transaction.

[D]  Includes the $11.3 million non-cash, pre-tax gain from the sale of the
     workover services business to Boots & Coots International Well Control,
     Inc.
