                      ENSCO REPORTS SECOND QUARTER RESULTS

         Dallas, Texas, July 18, 2002....ENSCO International Incorporated (NYSE:
ESV) reported net income of $23.3 million ($.17 per diluted share) on revenues
of $157.2 million for the three months ended June 30, 2002, compared to net
income of $61.2 million ($.44 per diluted share) on revenues of $215.5 million
for the year earlier quarter.

         ENSCO's net income for the first six months of 2002 was $39.5 million,
or $.29 per diluted share, on revenues of $299.5 million, compared to net income
of $108.1 million, or $.77 per diluted share, on revenues of $410.8 million for
the prior six month period. Included in the results for the six months ended
June 30, 2002 is a $5.8 million gain ($3.8 million after tax or $.03 per diluted
share) in connection with an insurance claim relating to the ENSCO 51 jackup
rig, which sustained extensive damage from a natural gas well fire in March of
2001.

         The average day rate for ENSCO's jackup rig fleet was $42,100 for the
second quarter of 2002, compared to $52,600 in the year earlier period.
Utilization for the Company's jackup fleet was 87% in the most recent quarter,
versus 91% in the second quarter of 2001. Excluding rigs in a shipyard for
regulatory inspection and enhancement, jackup utilization was 94% in the most
recent quarter, compared to 98% in the year earlier period.

         In ENSCO's marine transportation segment, the average day rate for the
Company's marine fleet was $5,900 in the second quarter of 2002, compared to
$8,300 in the year earlier period. Utilization for the marine fleet was 73% in
the quarter ended June 30, 2002, versus 84% in the second quarter of 2001.

         Carl Thorne, Chairman and Chief Executive Officer of ENSCO, commented
on the Company's recent results and outlook, "Second quarter results were
somewhat better than anticipated due primarily to the rescheduling of various
shipyard activity and the resulting additional revenue days in the quarter, and
the pace of day rate improvement in the Gulf of Mexico being slightly in excess
of that anticipated.





         "We continue to make progress relative to increasing the capability and
earnings potential of our rig and vessel fleets through enhancement,
redeployment, and additions. With regard to asset enhancement, six of our jackup
rigs were in a shipyard for planned regulatory and upgrade work during the most
recent quarter. We also anticipate having as many as six of our rigs in a
shipyard during the third quarter.

         "In connection with asset redeployment, we have a term contract work
commitment with Shell in Nigeria for one of our North Sea harsh environment
jackups (ENSCO 100) commencing this September. We have also received a term
contract commitment from TotalFinaElf requiring the relocation of one of our
Venezuelan barge rigs (ENSCO I) to Indonesia for work expected to commence by
the end of this year.

         "The proposed acquisition of Chiles Offshore Inc., which we announced
in May, is proceeding as planned. The Chiles shareholder meeting to vote on the
transaction is scheduled for August 7, 2002. Chiles owns and operates the newest
jackup fleet in the industry, with four ultra premium jackup rigs in service,
all having been built since 1999, and a fifth unit in the final stages of
construction. We look forward to the positive contribution we expect Chiles will
make to ENSCO.

         "As reported previously, we also continue to add to the high end of our
jackup fleet through new rig construction. The ENSCO 102, a newly built harsh
environment jackup rig in which we own a 25% interest with an option to purchase
the remaining 75%, is undergoing final outfitting and commissioning in
Singapore. We are in discussions with several operators relative to work
prospects in the region.

         "With regard to our markets, we continue to see strong demand for
premium jackup rigs in the Gulf of Mexico, and a continuing positive trend in
day rates. Internationally, the Asia Pacific region remains strong, and we have
a favorable contract backlog. These positive trends have been mitigated somewhat
by near term rate softness in the North Sea.

         "We continue to expect improvement in our results over the remaining
six months of this year, as rigs return to service upon completion of shipyard
work, and as results reflect the anticipated addition of the Chiles fleet
mid-third quarter. Third quarter 2002 earnings per share are expected to be in
the range of $.18 to $.23, including a contribution of approximately $.02 per
share from the Chiles rigs."
