BJ SERVICES REPORTS SECOND QUARTER EARNINGS

HOUSTON, April 23 /PRNewswire-FirstCall/ -- BJ Services Company (NYSE: BJS; PCX;
CBOE) reported net income of $44.8 million ($.28 per diluted share) for its
fiscal quarter ended March 31, 2003.

                                Financial Results
                     (in millions, except per share amounts)

                                              3 Months Ended
                                       3/31/03    12/31/02    3/31/02

         Revenue                        $534.6      $473.1     $442.4

         Net Income                     $44.8       $33.5      $39.0

         Diluted Earnings Per Share     $0.28       $0.21      $0.24

Consolidated revenue increased 13% sequentially, with US/Mexico Pressure Pumping
Services up 10%, International Pressure Pumping Services up 22%, and Other
Oilfield Services up 3%. Compared to prior year's second quarter, consolidated
revenue increased 21%. US/Mexico Pressure Pumping Services revenue increased 12%
and International Pressure Pumping Services increased 17%. Revenues from Other
Oilfield Services were up 74% over the prior year, due primarily to the addition
of completion fluids and completion tools service lines acquired with OSCA in
May 2002.

Operating income margins improved to 13.4% from 11.5% reported in the first
fiscal quarter. This was due to strong incremental results from the Company's
North American operations. Compared to the prior year's second quarter,
operating income margins declined from 13.7% due primarily to price declines in
the US market.

Interest expense, net was flat sequentially and increased $3.3 million from the
prior year's second quarter as a result of the issuance of convertible debt used
to finance the OSCA acquisition.

Capital spending was $36.7 million for the quarter. Cash as of March 31, 2003
was $122.0 million. Debt (net of cash) to total capitalization was 19.6% at the
end of March, down from 21.7% at the end of December.

U.S./Mexico Pressure Pumping Revenue

The Company's US/Mexico pressure pumping revenue increased 10% sequentially as
favorable commodity prices led the average U.S. drilling rig count during the
quarter up 6% to 901 rigs. Also contributing to the revenue improvement was
continued activity increase in Mexico. Compared to the second quarter of the
prior year, revenue increased 12% consistent with a 10% increase in rig
activity. During the quarter, 83% of the rigs were drilling for natural gas, the
same percentage as last year.

International Pressure Pumping Revenue

Canadian revenue increased 87% sequentially on the strength of a 74% increase in
rig activity. International revenue excluding Canada increased 3% sequentially
as activity gains in the U.K., West Africa, Malaysia, Argentina, and Russia more
than offset the impact of the strike in Venezuela.

Compared to the second quarter of the prior year, Canadian revenue increased
21%. While rig activity was up 29%, higher levels of shallow gas drilling
contributed to slightly lower revenue per rig. International revenue excluding

Canada increased 15% year-over-year led by improved activity in the North Sea,
West Africa, Malaysia, New Zealand, Brazil and Russia.

Other Oilfield Services

Revenue from the Company's Other Oilfield Services (completion fluids,
completion tools, process and pipeline services, tubular services and production
chemicals) increased 3% sequentially as a 20% increase in both the completion
fluids and completion tools service lines were offset by seasonal and project
declines in the tubular services and process and pipeline services. Compared to
the second quarter of the prior year, revenue for these services increased 74%
due to the addition of the completion fluids and completion tools service lines
acquired with OSCA. Process and pipeline services and production chemicals also
contributed to the year-over-year increase.

CEO Stewart Comments

Chairman and CEO Bill Stewart commented, "Our second fiscal quarter was one of
good financial performance for the Company. Sequentially, we experienced good
revenue improvement with solid incremental profit contribution. The revenue
improvement was better than earlier projected as drilling rig activity levels
exceeded our expectation for both the U.S. and Canadian markets. The long hoped
for drilling rig activity increase in the U.S. began to materialize during the
quarter resulting in an increase in 100 rigs drilling over the course of the
quarter."

"Looking forward, the North American natural gas fundamentals are strong and we
expect the U.S. market activity to continue to improve into the summer. We also
expect a normal seasonal decline in Canadian activity which will offset some of
the activity increase gains expected in the U.S. market for the quarter.
Accordingly, we believe earnings will be in the $.28 to $.31 range for our third
fiscal quarter and in the $1.15 to $1.20 range for the fiscal year ending
September 30, 2003."
