Exhibit 99.1

                Oil States Announces First Quarter 2004 Earnings

    HOUSTON, April 28 /PRNewswire-FirstCall/ -- Oil States International, Inc.
(NYSE: OIS) today reported net income of $16.2 million, or $0.32 per diluted
share, for the quarter ended March 31, 2004 compared to net income of
$13.4 million, or $0.27 per diluted share, in the first quarter of 2003.
Reported net income included the effect of a $5.4 million income tax credit,
which reduced the tax provision calculated at statutory rates, due to the
partial reversal of valuation allowances applied against net operating loss
carryforwards.  As a result, the Company's effective tax rate was 8.6% versus
previous effective rate guidance of 33%.  If the Company had reported earnings
with the previously estimated 33% rate, the Company would have reported net
income of $11.8 million, or $0.24 per diluted share, without the tax credit.
    The Company's first quarter results were characterized by further
improvements in its Well Site Services and Tubular Services segments, offset
by weak results in its Offshore Products segment.  The Company generated
$204.2 million of revenues and $27.8 million of EBITDA (defined as net income
plus interest, taxes, depreciation and amortization) in the first quarter of
2004 compared to $185.6 million and $26.9 million, respectively, in the first
quarter of 2003.(A)  Oil States' revenues and EBITDA for the quarter increased
10% and 3%, respectively, from last year's results.  Strong North American
drilling and completion activity coupled with rising steel prices and
contributions from recent acquisitions led to year-over-year and sequential
improvements in the Well Site Services and Tubular Services segments.  These
improvements were substantially offset by diminished results from Offshore
Products primarily due to decreased activity and revenues during the quarter,
which also led to reduced cost absorption in several of the Company's
manufacturing facilities.
    During the first quarter of 2004, the Company recognized a $5.4 million
income tax benefit related to the partial reversal of valuation allowances
applied against net operating loss carryforwards.  Because the Company has
generated consolidated earnings and U.S. taxable income in the three year
period since its formation and expects to generate future taxable income, the
Company reduced the allowance and recognized the benefit of a majority of its
net operating loss carryforwards.  The Company recognized the benefit of
$44.2 million of its $63.2 million of available net operating loss
carryforwards during the quarter.  As a result, the Company's effective tax
rate for the first quarter of 2004 was 8.6% compared to an effective tax rate
of 29.0% in the first quarter of 2003.  The Company expects that the effective
rate for the full year 2004 will be approximately 30%.  Capital expenditures
during the first quarter of 2004 totaled $8.9 million.

    BUSINESS SEGMENT RESULTS

    Well Site Services
    Well Site Services generated significantly improved results during the
first quarter of 2004 due to improved activity in the U.S. land drilling
market, a strong Canadian drilling season and contributions from capital
investments and acquisitions completed in recent months.  For the first
quarter of 2004, Well Site Services reported revenues of $96.1 million and
EBITDA of $23.8 million compared to revenues of $78.8 million and EBITDA of
$19.5 million in the first quarter of 2003.  These results represent a 22%
year-over-year increase in both revenues and EBITDA.  Within Well Site
Services, the accommodations business benefited from strong Canadian drilling
activity as the Canadian rig count increased 7% from the first quarter 2003.
The accommodations business also benefited from significantly increased
contributions from an international catering and facility management contract.
The Company's land drilling operations generated significantly improved
results year-over-year due to continued strong U.S. land drilling activity and
contributions from two newly built rigs working in West Texas.  Well Site
Services also benefited from eight rental tool acquisitions completed over the
past six months.  Further improvements in the segment's results were hindered
by continued weakness in the Gulf of Mexico market which negatively impacted
the workover, rental tool and Gulf Coast accommodations businesses.

    Offshore Products
    During the first quarter of 2004, Offshore Products reported $41.9 million
of revenues and $1.5 million of EBITDA, compared to $57.6 million of revenues
and $7.5 million of EBITDA in the first quarter of 2003.  Revenues declined
27% year-over-year as a result of timing delays in deepwater infrastructure
spending.  Gross margin for the first quarter fell to 17% from the 22% gross
margin in the first quarter of 2003.  These lower margins were largely due to
lower overhead absorption resulting from reduced activity and unfavorable
product mix.  The segment also recorded a $0.4 million foreign exchange loss
because of the decline of the U.S. dollar relative to the British pound.
However, Offshore Products' outlook improved during the quarter as backlog
grew to $76.9 million at March 31, 2004 compared to $62.6 million at
December 31, 2003, a 23% increase.

    Tubular Services
    Tubular Services generated $66.2 million of revenues and $4.0 million of
EBITDA in the first quarter compared to $49.2 million of revenues and
$1.2 million of EBITDA in the first quarter of 2003.  Tubular Services
benefited from a 30% year-over-year increase in U.S. land drilling activity
and a significant increase in OCTG prices during the quarter, partially offset
by reduced offshore activity in the U.S.  OCTG shipments were 67,300 tons in
the first quarter of 2004 compared to 56,600 tons shipped in the first quarter
of 2003.  Gross margin for Tubular Services was 8.9% in the first quarter of
2004 compared to 5.9% in the first quarter of 2003.  The Company's OCTG
inventory at March 31, 2004 was $59.3 million compared to $64.5 million at
December 31, 2003 and $65.1 million at March 31, 2003.  As of March 31, 2004,
approximately 75% of Oil States' OCTG inventory was committed to customer
orders.
    "North American activity continued to be strong in the first quarter of
2004, driving solid results in our Tubular Services and Well Site Services
businesses," stated Douglas E. Swanson, Oil States' President and Chief
Executive Officer.  "We experienced good activity in Canada during the winter
drilling season and improving land activity in the U.S., partially offset by
continued weakness in the Gulf of Mexico.  Our Tubular Services segment
benefited from rising steel and OCTG prices, creating margin expansion
opportunities.  We had a difficult quarter in our Offshore Product segment due
to reduced activity, but we believe that we have seen the trough given the
growth in our backlog as of quarter end.  The outlook for each of our
businesses is improving.  Although we will experience the normal seasonal
decline in our Canadian business in the second quarter, we expect continued
solid results in Well Site Services from the anticipated strong U.S. market
and growth opportunities in Canada due to future oil sands construction
activity.  Tubular Services should continue to benefit from the strong U.S.
land drilling market and tight OCTG supplies.  Based on our current backlog,
we believe Offshore Products will have improved results during the remainder
of 2004."

the Securities Act of 1933 and Section 21E of the Securities Exchange Act of

     (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.
