         OIL STATES ANNOUNCES SECOND QUARTER EARNINGS OF $0.88 PER SHARE

    HOUSTON, Aug. 2 /PRNewswire-FirstCall/ -- Oil States International, Inc.
(NYSE: OIS) today reported net income for the quarter ended June 30, 2006 of
$45.3 million, or $0.88 per diluted share. These results compare to $24.9
million, or $0.49 per diluted share, reported in the second quarter of 2005.
With continuing strong activity and contributions from recent capital
investments and acquisitions, Oil States recognized year-over-year growth in
revenues and EBITDA (defined as net income plus interest, taxes, depreciation
and amortization) in the second quarter of 2006 of 29% and 57%, respectively.(A)

    The Company generated $463.4 million of revenues and $84.1 million of EBITDA
in the second quarter of 2006 compared to $358.5 million and $53.6 million,
respectively, in the second quarter of 2005. Year-over-year improvements in Well
Site Services and Offshore Products contributed to strong second quarter
results. Well Site Services reported significantly higher revenues and EBITDA
due to high levels of North American drilling activity, capital investments made
in the past year and contributions from the Stinger acquisition completed in May
2005. Offshore Products also generated significantly improved revenues and
EBITDA due to the acceleration in deepwater development spending by its
customers. In addition, the outlook for Offshore Products continued to
strengthen as backlog increased 27% during the quarter to $280.6 million.
Tubular Services reported a year-over-year improvement in revenues due to
increased U.S. drilling activity and the benefit of the Phillips acquisition
completed in June 2005. EBITDA for Tubular Services was slightly lower than the
prior year as a result of lower margins and product mix.

    The Company also benefited from a reduced effective tax rate during the
second quarter of 2006 due to statutory rate changes, primarily in Canada. These
rate changes benefited second quarter earnings by $2.3 million, or $0.05 per
diluted share. As a result, the Company recognized an effective tax rate of
32.2% in the quarter compared to 36.9% in the second quarter of last year. The
Company currently expects the effective tax rate to approximate 36% for the
remainder of 2006.

    For the first half of 2006, the Company reported net income of $98.2
million, or $1.92 per diluted share, on revenues of $959.6 million and EBITDA of
$188.6 million. For the first half of 2005, the Company reported net income of
$50.1 million, or $0.99 per diluted share, on revenues of $690.4 million and
EBITDA of $106.1 million. This performance represents year-over-year revenue and
EBITDA increases of 39% and 78%, respectively. As a result, operating income
increased 77% to $149.2 million in the first half of 2006 from $84.2 million in
the first half of 2005. Net income in the first half of 2006 included the
recognition 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. (Amex: WEL).

    BUSINESS SEGMENT RESULTS
    Well Site Services
    Well Site Services generated strong second quarter results due to year-
over-year improvements in North American land activity and contributions from
capital investments and acquisitions made over the past year, partially offset
by the sale of the hydraulic workover business completed in the first quarter of
2006. For the second quarter of 2006, Well Site Services generated revenues of
$154.0 million and EBITDA of $54.3 million compared to $126.8 million and $30.1
million, respectively, in the second quarter of 2005. The 21% year-over-year
increase in revenues and 81% increase in EBITDA at Well Site Services resulted
from several factors including the acquisition of Stinger completed in May 2005,
stronger accommodations activity in Canada, improving U.S. drilling and
completion activity, benefits of recent capital expenditures primarily in the
drilling services, rental tools and accommodations businesses and improved
pricing in several product lines, the most significant of which was in drilling
services. These results were partially offset by the conversion of the Company's
investment in its workover services business (which accounted for $10.9 million
in revenues and $3.0 million in EBITDA in the second quarter of 2005) to equity
accounting with the sale of the business to Boots & Coots in March 2006.



    The accommodations business generated $75.0 million of revenues and $19.7
million of EBITDA compared to $65.0 million and $9.5 million, respectively, in
the second quarter of 2005. The accommodations business benefited from improving
activity in the oil sands region of northern Canada, a 12% strengthening of the
Canadian dollar against the U.S. dollar and the realization of increased
revenues from standby fees and guarantees of $3.8 million, or $0.05 per diluted
share, in its Canadian accommodations business. These improvements were
partially offset by lower international facility management activity due to
contract completion and the completion of a major expansion project by an oil
sands customer. Drilling services reported revenues and EBITDA of $32.2 million
and $15.4 million, respectively, in the second quarter of 2006 compared to $19.7
million of revenues and $5.9 million of EBITDA in the second quarter 2005 due to
improved utilization and pricing, more advantageous contract terms and rig fleet
expansion (added three new rigs since June 15, 2005). During the second quarter,
rental tools generated $46.8 million of revenues and $18.4 million of EBITDA
compared to $31.2 million of revenues and $11.6 million of EBITDA during the
second quarter of 2005. This year-over-year growth was due to the Stinger
acquisition, improved pricing and increased North American drilling and
completion activity.

    Offshore Products
    During the second quarter of 2006, Offshore Products generated record
quarterly results, reporting $93.7 million of revenues and $17.9 million in
EBITDA compared to $63.9 million and $7.9 million, respectively, in the second
quarter of 2005. Gross margin percentage for the second quarter increased to 27%
from 22% in the second quarter of 2005 primarily due to increased activity and
fixed cost absorption in the majority of the Company's manufacturing locations,
increased contributions from the connector products and rig equipment businesses
and improved activity and margins in the subsea pipeline business. Backlog
continued to increase, totaling a new record of $280.6 million at June 30, 2006
compared to $220.8 million at March 31, 2006 and $110.7 million as of December
31, 2005.

    Tubular Services
    Tubular Services reported revenues of $215.7 million and EBITDA of $17.5
million for the second quarter of 2006 compared to $167.8 million and $18.4
million, respectively, in the second quarter of 2005. Tubular Services' OCTG
shipments increased 16% to 116,800 tons from 100,600 tons in the second quarter
of 2005. Gross margins in the second quarter of 2006 declined to 9.3% from 12.7%
in the second quarter of 2005 because of static OCTG mill pricing and a higher
percentage of carbon OCTG sales. The segment continued to see reduced demand for
higher margin seamless alloy tubulars while strong land based drilling activity
increased our lower margin carbon grade sales. The Company's OCTG inventory as
of June 30, 2006 was $269.8 million compared to $265.8 million as of March 31,
2006 and $274.2 million as of December 31, 2005. As of June 30, 2006,
approximately 65% of Oil States' OCTG inventory was committed to customer
orders.

    "With strengthening deepwater construction activity, expanding capacity in
the oil sands region and improved North American activity, Oil States had a very
strong second quarter," stated Douglas E. Swanson, Oil States' Chief Executive
Officer. "While we clearly benefited from continued strength in U.S. land
drilling and completion activity, much of the upside in the second quarter was
driven by activity in two secular, oil-focused growth markets: deepwater
infrastructure spending and Canadian oil sands development. Deepwater
infrastructure spending drove improved results in our Offshore Products business
with record financial results and record quarter end backlog. For a public
oilfield service company, we have unique exposure to the oil sands activity
through our accommodations business. This market has been a major focus for our
strategic growth and our 2006 capital expenditure plan. Looking forward, our
current expectation for third quarter 2006 earnings is in a range of $0.82 to
$0.87 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 June 30, 2006, the Company had approximately $99.3 million available
     under its revolving credit facility.
(C)  Reflects two months' results for the workover services business, which was
     sold to Boots & Coots International Well Control, Inc. effective on March
     1, 2006.
(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.
