         Oil States Announces First Quarter Earnings of $1.31 per Share

    HOUSTON, April 29 /PRNewswire-FirstCall/ -- Oil States International, Inc.
(NYSE: OIS) today reported net income for the quarter ended March 31, 2008 of
$66.5 million, or $1.31 per diluted share, compared to $52.5 million, or $1.05
per diluted share, reported in the first quarter of 2007. Oil States recognized
year-over-year growth in revenues and EBITDA (defined as net income plus
interest, taxes, depreciation and amortization) of 25% and 28%, respectively, in
the first quarter of 2008.(A)

    Significant year-over-year improvements in our oil sands accommodations
business, increased profitability in our Offshore Products segment and
contributions from two rental tool acquisitions completed during the third
quarter of 2007 along with increased activity in Tubular Services led to revenue
and EBITDA growth in the first quarter of 2008. During the quarter, the Company
generated $601.2 million of revenues and $125.8 million of EBITDA compared to
$480.5 million and $98.0 million, respectively, in the first quarter of 2007.
Consolidated operating income in the first quarter of 2008 was $101.3 million
compared to $82.9 million for the corresponding quarter of 2007.

    The Company recognized an effective tax rate of 32.7% in the first quarter
of 2008 compared to 34.1% in the first quarter of 2007. The lower effective tax
rate in the first quarter of 2008 was primarily due to lower tax rates
applicable to foreign income. The Company spent $60.8 million in capital
expenditures during the first quarter of 2008 primarily related to expansions to
our rental tool operations and on-going construction of the recently announced
Conklin Lodge as well as continued expansion at Wapasu Lodge, both of which
serve customers in the oil sands region of Canada.

    BUSINESS SEGMENT RESULTS

    (Unless otherwise noted, the following discussion compares the quarterly
results from the first quarter of 2008 to the results from the first quarter of
2007.)

    Well Site Services

    For the first quarter of 2008, Well Site Services generated revenues of
$265.6 million and EBITDA of $97.6 million, compared to $178.1 million and $74.0
million, respectively, in the first quarter of 2007, representing year-over-year
increases of 49% and 32%, respectively. The increase in EBITDA was primarily due
to improved results from the oil sands accommodations and contributions from the
two rental tool acquisitions closed in the third quarter of 2007, partially
offset by lower margins from the Company's drilling and rental tools operations.

    The accommodations business reported revenues of $146.3 million and EBITDA
of $60.9 million, for the first quarter of 2008, compared to revenues and EBITDA
of $93.6 million and $39.1 million, respectively, in the first quarter of 2007.
Accommodations revenue and EBITDA each increased 56%, primarily due to
contributions from additional room capacity at our major oil sands lodges, which
was up over 70% from ending first quarter 2007 capacity levels. Drilling
services generated revenues and EBITDA of $36.8 million and $11.2 million in the
first quarter of 2008, respectively, compared to $30.9 million of revenues and
EBITDA of $12.7 million in the first quarter 2007. The year-over-year
improvement in revenue was due to higher pricing and drilling rig additions made
in 2007, but was offset by lower utilization in the Rockies caused by seasonal
weather issues and by higher operating costs. Rental tools generated $82.5
million of revenues and $25.5 million of EBITDA in the first quarter of 2008
compared to revenue of $53.6 million and EBITDA of $22.2 million in the first
quarter of 2007. This year-over-year growth was primarily due to two
acquisitions completed in the third quarter of 2007, partially offset by
softness in a few regional markets, isolated project delays and start-up costs
in Mexico.



    Offshore Products

    The Offshore Products segment reported revenue and EBITDA of
$126.9 million and $24.1 million, respectively, in the first quarter of 2008,
compared to $119.0 million of revenues and $20.4 million in EBITDA in the first
quarter of 2007. Offshore Products' revenues were up 7% and EBITDA was up 18%
year-over-year primarily due to the mix of higher margin bearing and connector
products and improved margins on drilling equipment deliveries. Backlog totaled
$383.5 million at March 31, 2008 which represented a 6% increase from the $362.2
million reported as of December 31, 2007.

    Tubular Services

    Tubular Services generated revenues of $208.8 million and EBITDA of $10.1
million during the first quarter of 2008 compared to revenues of
$183.4 million and EBITDA of $8.4 million in the first quarter of 2007. Tubular
Services' revenues increased 14% year-over-year while OCTG shipments increased
24% to 127,100 tons in the first quarter of 2008 up from 102,600 tons shipped in
the first quarter of 2007. Partially offsetting the volume increase was lower
realized revenues per ton which decreased 8% year-over-year. However, during the
quarter, OCTG manufacturers announced several price increases which take effect
during the second quarter of 2008. Gross margins in the first quarter of 2008
were flat year-over-year at approximately 6%. The Company's OCTG inventory level
at March 31, 2008 was $190.4 million which was essentially flat with the
December 31, 2007 level of $191.4 million, but down significantly from the March
31, 2007 level of $251.4 million.

    "Our lodges and mobile camp equipment working in the oil sands region of
Canada were significant drivers of our growth in the first quarter of 2008,"
stated Cindy B. Taylor, Oil States' President and Chief Executive Officer. "We
are realizing the benefits of our capital expenditures made in our
accommodations business as is reflected in our record results for the quarter.
Additionally, margins improved in our Offshore Products segment which supports
global deepwater infrastructure development. With the current tightness in OCTG
supply coupled with recently announced mill price increases and surcharges, we
expect our Tubular Services segment to generate stronger margins and profits in
the second quarter of 2008. Our current expectation for second quarter 2008
earnings is in a range of $0.90 to $0.97 per diluted share considering the
normal seasonal declines in activity in our Canadian based operations."

    (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. The following table sets
         forth a reconciliation of EBITDA to net income, which is the most
         directly comparable measure of financial performance calculated under
         generally accepted accounting principles:
