Exhibit 99.1

       OIL STATES INTERNATIONAL TO SELL $125 MILLION OF 2 3/8% CONTINGENT
                            CONVERTIBLE SENIOR NOTES

HOUSTON, June 15 /PRNewswire-FirstCall/ -- Oil States International, Inc. (NYSE:
OIS) today announced that it has agreed to sell $125 million aggregate principal
amount of its 2 3/8% contingent convertible senior notes due 2025 through a
placement to qualified institutional buyers pursuant to Rule 144A. The company
has granted the initial purchaser of the notes a 30-day option to purchase up to
an additional $50 million aggregate principal amount of the notes. The placement
of the notes is expected to close on June 21, 2005.

The notes will be senior, unsecured obligations of the Company and will bear
interest at a rate of 2 3/8% per annum. The notes will mature on July 1, 2025
and may not be redeemed by the company prior to July 6, 2012. Holders of the
notes may require the company to repurchase some or all of the notes on July 1,
2012, 2015 and 2020. The notes provide for a net share settlement, and therefore
may be convertible, under certain circumstances, into a combination of cash, up
to the principal amount of the notes, and common stock of the company, if there
is any excess above the principal amount of the notes, at an initial conversion
price of $31.75.

The company stated that it expects to use approximately $30 million of the net
proceeds of the offering to repurchase shares of its common stock that it has
agreed to purchase from the initial purchaser of the notes and the remaining
portion of the net proceeds to repay its $25.0 million bridge loan and to repay
approximately $66.0 million of borrowings under its senior secured credit
facility.
