    OIL STATES ANNOUNCES RECORD THIRD QUARTER EARNINGS OF $0.60 PER SHARE

    HOUSTON, Oct. 31 /PRNewswire-FirstCall/ -- Oil States International, Inc.
(NYSE: OIS) today reported a 95% year-over-year increase in net income for the
quarter ended September 30, 2005. Net income for the third quarter of 2005
increased to $30.3 million, or $0.60 per diluted share, from $15.5 million, or
$0.31 per diluted share, in the third quarter of 2004.

    With year-over-year increases in profitability from all of its business
segments, Oil States' revenues and EBITDA (defined as net income plus interest,
taxes, depreciation and amortization) for the third quarter of 2005 increased
57% and 71%, respectively.(A) The Company generated $394.1 million of revenues
and $64.1 million of EBITDA in the third quarter of 2005 compared to $251.5
million and $37.6 million, respectively, in the third quarter of 2004. The
improved results were primarily generated by increased volumes and prices at
Tubular Services, increased accommodations activity in the oil sands region of
Canada, increased U.S. drilling activity and incremental results from capital
expenditures and acquisitions completed over the past twelve months.

    Tubular Services benefited from continued strong U.S. land drilling
activity, limited oil country tubular goods ("OCTG") supplies and the
acquisition of Phillips Casing and Tubing, L.P. ("Phillips"), completed in June
2005. Well Site Services generated increased revenues and EBITDA due to strong
U.S. land drilling and Canadian oil sands activity, capital investments made in
the past year and contributions from the Elenburg and Stinger acquisitions
completed in the first half of 2005. Offshore Products also improved
significantly year-over-year as volumes and margins expanded with the recovery
in deepwater development spending. The Company's effective tax rate in the third
quarter of 2005 was 36.9% compared to an effective tax rate of 41.4% in the
third quarter of 2004.

    For the nine months ended September 30, 2005, the Company reported net
income of $80.4 million, or $1.59 per diluted share, on revenues of $1.1 billion
and EBITDA of $170.2 million. During the first nine months of 2004, the Company
reported net income of $43.8 million, or $0.88 per diluted share, on revenues of
$677.9 million and EBITDA of $96.1 million. This performance represents
year-over-year revenue and EBITDA increases of 60% and 77%, respectively. As a
result, operating income nearly doubled, increasing to $135.5 million from $68.7
million in the first nine months of 2004. The 2004 year-to-date results included
the Company's recognition of a $5.4 million income tax benefit related to the
partial reversal of valuation allowances applied against net operating loss
carryforwards. The effective tax rate in the first nine months of 2004 was 31.9%
compared to 36.9% during the same period in 2005. The Company expects that the
effective rate for the full year 2005 will be approximately 35% - 38%.

    BUSINESS SEGMENT RESULTS
    Well Site Services

    For the third quarter of 2005, Well Site Services generated $141.5 million
of revenues and $38.4 million of EBITDA compared to $79.4 million of revenues
and $20.5 million of EBITDA in the third quarter of 2004. The 78% year-over-
year increase in revenues and 88% increase in EBITDA at Well Site Services were
primarily due to recently completed acquisitions, a 16% increase in U.S.
drilling activity, increased activity in Canadian accommodations and
contributions from recent capital expenditures primarily in the accommodations,
drilling services and rental tools businesses.



    The rental tools business reported significantly improved results during the
third quarter of 2005 due to the acquisition of Stinger, improving U.S. drilling
activity and the impact of price increases, partially offset by hurricane
related disruptions in the Gulf of Mexico. For the third quarter of 2005, rental
tools contributed $40.0 million of revenues and $14.6 million of EBITDA compared
to $16.2 million of revenues and $4.8 million of EBITDA in the third quarter of
2004. Of the $23.8 million increase in rental tools' revenue and the $9.8
million increase in EBITDA, $20.6 million of revenues and $9.7 million of EBITDA
were generated by Stinger. Drilling services' revenues and EBITDA were up 88%
and 102%, respectively, from the third quarter of 2004 due to incremental
earnings from the seven rigs acquired in the Elenburg acquisition, two
additional newly built rigs added to the fleet and higher dayrates and cash
margins. Elenburg contributed $6.6 million of revenues and $2.2 million of
EBITDA during the third quarter of 2005 of a total revenue and EBITDA increase
of $11.3 million and $4.4 million, respectively, from the Company's drilling
services operations. Accommodations' revenues and EBITDA were up 59% and 26%,
respectively, due primarily to increased activity in the oil sands region of
Canada, partially offset by reduced international facility management activity.
Accommodation's gross margin percentage was lower during the quarter due to a
greater percentage of revenues being generated by manufacturing activities,
which generally earn a lower margin than accommodation rental and service
activities.

    Offshore Products
    Offshore Products reported third quarter 2005 revenues of $64.3 million and
EBITDA of $8.3 million compared to revenues of $55.3 million and EBITDA of $5.0
million in the third quarter of 2004. This 16% increase in revenues and 67%
increase in EBITDA was primarily the result of higher activity levels and
increased fixed cost absorption. Gross margin percentage for the third quarter
increased to 22% from 19% in the third quarter of 2004. At the end of the third
quarter of 2005, backlog was $119.4 million compared to $113.5 million at June
30, 2005 and $97.5 million as of December 31, 2004.

    Tubular Services
    Tubular Services had another record quarter generating $188.3 million of
revenues and $20.4 million of EBITDA compared to $116.9 million of revenues and
$14.3 million of EBITDA in the third quarter of 2004. These record results were
primarily due to contributions from the Phillips acquisition, increases in OCTG
pricing and increased U.S. drilling activity which strengthened demand for our
tubular products and services. Third quarter gross margin percentage was 12.3%
compared to 14.4% in the third quarter of 2004. Our Tubular Services segment's
gross margin as a percent of revenues decreased because of product mix and less
frequent and smaller OCTG price increases. OCTG shipments were 104,100 tons in
the third quarter of 2005 compared to 90,100 tons shipped in the third quarter
of 2004. The Company's OCTG inventory as of September 30, 2005 was $241.5
million compared to $189.7 million at June 30, 2005 and $123.6 million at
December 31, 2004. As of September 30, 2005, approximately 71% of Oil States'
OCTG inventory was committed to customer orders.

    "Oil States had a record third quarter of 2005 as we continued to experience
strong activity in virtually all of our markets and as we enjoyed incremental
earnings from recent capital expenditures and acquisitions," stated Douglas E.
Swanson, Oil States' President and Chief Executive Officer. "Although difficult
to quantify, the hurricanes disrupted our Gulf Coast operations, causing a $0.02
to $0.04 per share reduction in our operating results. With activity for our
Gulf Coast businesses beginning to recover from the storm interruptions, we
expect fourth quarter earnings to be in a range of $0.60 to $0.65 per diluted
share."

    The foregoing contains forward-looking statements within the meaning of the
Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934.
Forward-looking statements are those that do not state historical facts and are,
therefore, inherently subject to risks and uncertainties. The forward-looking
statements included herein are based on current expectations and entail various
risks and uncertainties that could cause actual results to differ materially
from those forward-looking statements. Such risks and uncertainties include,
among other things, risks associated with the general nature of the oilfield
service industry and other factors discussed within the "Business" section of
the Form 10-K for the year ended December 31, 2004 filed by Oil States with the
SEC on March 2, 2005.

     (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.
