         OIL STATES ANNOUNCES FOURTH QUARTER EARNINGS OF $0.82 PER SHARE

    HOUSTON, Feb. 7 /PRNewswire-FirstCall/ -- Oil States International, Inc.
(NYSE: OIS) today reported net income for the quarter ended December 31, 2005 of
$41.4 million, or $0.82 per diluted share. These results compare to $15.5
million, or $0.31 per diluted share, reported in the fourth quarter of 2004. Net
income for the fourth quarter of 2005 included the benefit of a reduction in the
estimated annual effective tax rate and the Company's recognition of a $4.6
million income tax benefit related to the reversal of substantially all of its
remaining valuation allowances applied against net operating loss carryforwards.
The combined tax rate benefit in the quarter totaled approximately $0.13 per
diluted share.

    As activity in many of its key markets improved combined with the results of
current year acquisitions and capital expenditures, Oil States recognized
year-over-year growth in revenues and EBITDA (defined as net income plus
interest, taxes, depreciation and amortization) in the fourth quarter of 2005 of
53% and 101%, respectively.(A) The Company generated $447.1 million of revenues
and $72.4 million of EBITDA in the fourth quarter of 2005 compared to $293.1
million and $36.0 million, respectively, in the fourth quarter of 2004. The
improved results were primarily generated by increased volumes and prices in the
Tubular Services segment, increased U.S. drilling activity, incremental benefits
of capital expenditures and acquisitions completed over the past twelve months
and significantly improved Offshore Products results.

    This year-over-year improvement was generated by higher earnings from all
business segments. Tubular Services benefited from continued strong U.S. land
drilling activity driving demand for its oil country tubular goods ("OCTG") and
from the acquisition of Phillips Casing and Tubing, L.P. ("Phillips"), completed
in June 2005. Well Site Services reported significantly higher revenues and
EBITDA due to strong U.S. land drilling 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 activity increased with the recovery in
deepwater development spending. The Company's effective tax rate in the fourth
quarter of 2005 was 24.8% compared to an effective tax rate of 36.4% in the
fourth quarter of 2004.

    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. During 2004, the Company reported net income of $59.4
million, or $1.19 per diluted share, on revenues of $971.0 million and EBITDA of
$132.1 million. This performance represents year-over-year increases in revenues
and EBITDA of 58% and 84%, respectively. As a result, operating income doubled,
increasing to $194.6 million from $95.1 million in 2004. The 2004 results
included the Company's recognition of a $6.9 million income tax benefit related
to the partial reversal of valuation allowances applied against net operating
loss carryforwards. The effective tax rate in 2004 was 33.1% compared to 33.3%
during 2005.

    BUSINESS SEGMENT RESULTS

    Well Site Services

    Well Site Services finished 2005 with significant growth. The fourth quarter
of 2005 benefited from an 18.4% increase in the U.S. rig count, capital
investments made over the past year and acquisitions completed in the segment.
For the fourth quarter of 2005, Well Site Services generated $152.8 million of
revenues and $40.4 million of EBITDA compared to $88.5 million of revenues and
$21.3 million of EBITDA in the fourth quarter of 2004. The 73% year-over-year
increase in revenues and 89% increase in EBITDA at Well Site Services were
primarily due to the acquisition of Stinger in May 2005, higher accommodations
manufacturing activity, improved U.S. drilling and completion activity, benefits
of recent capital expenditures primarily in the drilling services and rental
tools businesses and improved pricing in several product lines.

    During the fourth quarter, rental tools generated $44.5 million of revenues
and $16.4 million of EBITDA compared to $18.3 million and $6.4 million,
respectively, in the fourth quarter of 2004. The acquisition of Stinger
contributed $23.7 million of revenues and $10.5 million of EBITDA. Land drilling
reported a 119% year-over-year increase in revenues and 228% increase in EBITDA
due to contributions from the Elenburg acquisition, additional rigs added to the
fleet, pricing improvements and movement from footage to daywork contracts in
its Texas operations. Elenburg contributed $7.5 million of revenues and $2.4
million of EBITDA during the fourth quarter of 2005.



    Accommodations' revenues were up 43% year-over-year in the fourth quarter;
however, EBITDA was down 6% due to revenue mix weighted more to lower margin
manufacturing work and increased repair and maintenance costs in Canada incurred
in preparation for the winter drilling season. During the quarter, the Company
also experienced lower than expected activity due to extended warm weather in
Canada and significant holiday downtime.

    Offshore Products

    During the fourth quarter of 2005, Offshore Products generated revenues of
$76.5 million and EBITDA of $12.4 million compared to revenues of $60.7 million
and EBITDA of $4.9 million in the fourth quarter of 2004 as deepwater
development spending continued to increase. Gross margin percentage for the
fourth quarter increased to 25% from 16% in the fourth quarter of 2004 primarily
due to increased service work and repair products delivered for hurricane
recovery work. At the end of the fourth quarter of 2005, backlog totaled $110.7
million compared to $119.4 million as of September 30, 2005 and $97.5 million as
of December 31, 2004.

    Tubular Services

    Tubular Services had its fourth consecutive record quarter generating $217.8
million of revenues and $22.5 million of EBITDA compared to $143.9 million of
revenues and $12.7 million of EBITDA in the fourth quarter of 2004. These record
results were primarily due to contributions from the Phillips acquisition,
increased OCTG pricing and increased U.S. drilling activity which strengthened
demand for our tubular products and services. Fourth quarter gross margin
percentage was 11.0% compared to 10.4% in the fourth quarter of 2004. OCTG
shipments during the fourth quarter were 118,600 tons compared to 97,800 tons
shipped in the fourth quarter of 2004. The Company's OCTG inventory as of
December 31, 2005 was $274.2 million compared to $241.5 million at September 30,
2005 and $123.6 million at December 31, 2004. As of December 31, 2005,
approximately 67% of Oil States' OCTG inventory was committed to customer
orders.

    "Oil States finished 2005 with strong fourth quarter results as activity
reached record levels in the majority of our markets," stated Douglas E.
Swanson, Oil States' President and Chief Executive Officer. "Overall, we are
expecting another strong year for Oil States in 2006. Our current expectation
for first quarter 2006 earnings is in a range of $0.75 to $0.80 per diluted
share after expensing stock options, which is estimated to reduce first quarter
2006 earnings by approximately $0.02 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, 2005, the Company had approximately $90.4 million
     available under its revolving credit facility.
