Houston, Texas

FOR IMMEDIATE RELEASE

     ATWOOD OCEANICS,  INC.,  Houston-based  International  Drilling Contractor,
announced  today that the Company  earned net income of  $7,021,000  or $.45 per
diluted share,  on revenues of $46,124,000  for the quarter ended  September 30,
2005,  compared  to net  income of  $3,344,000  or $.24 per  diluted  share,  on
revenues of $42,933,000 for the quarter ended September 30, 2004. For the twelve
months ended September 30, 2005, the Company earned net income of $26,371,000 or
$1.69 per diluted share, on revenues of  $176,156,000  compared to net income of
$7,587,000 or $.54 per diluted share, on revenues of $163,454,000 for the twelve
months ended September 30, 2004.

     In the Company's Form 8-K filed on November 22, 2005,  the Company  advised
that at this time diluted earnings per share for the quarter ended September 30,
2005 was expected to be between $.20 and $.25. On December 1, 2005,  the Company
received  notification  from the  Internal  Revenue  Service  that a  previously
reserved  $3.3 million U.S.  income tax refund the Company had been pursuing for
over two years has been  approved for  payment.  Based upon this  approval,  the
Company  reduced  income tax  provision by the refund amount for the quarter and
year ended  September  30,  2005 and also  recorded  approximately  $300,000  of
interest income relating to the tax refund. This tax refund and related interest
income  increased  diluted  earnings  per share for the  quarter  and year ended
September 30, 2005 by $.22 and $.23, respectively.

Note          1 - On December 1, 2005, the Company received notification from

              over two years has been approved for payment. Based upon this
