                    APACHE TO EXPAND GAS MARKETING OPERATIONS

         Houston, June 24, 2003 - Apache Corporation (NYSE: APA) today announced
that it will begin directly marketing its U.S. natural gas production, beginning
with its July production. The company has marketed its international oil and gas
production, Canadian gas and North American liquid hydrocarbons for some time.

         Apache's U.S. natural gas production has been marketed by
Cincinnati-based Cinergy for the last five years. Apache and Cinergy have agreed
to terminate that relationship and also dismissed the arbitration pending
between them.

         "Five years ago, Apache was producing around 500 million cubic feet
(MMcf) of gas per day in the United States and Canada and our arrangement with
Cinergy made sense," said G. Steven Farris, chief executive officer and
president. "Today, with more than 1 billion cubic feet (Bcf) per day of gas
production in North America and significant changes in the gas marketing arena,
it is time for Apache to market its own gas."

APACHE MARKETING OPERATIONS--ADD 1

         Including gas from other producers, Apache will market approximately
1.2 Bcf of gas per day in North America: approximately 830 million cubic feet
(MMcf) per day in the United States and about 420 MMcf per day in Canada.

         The company has established an oil and gas marketing department headed
by Janine McArdle, a corporate vice president with an extensive energy marketing
background. "We've put together a great team and we are eager to get started,"
McArdle said.

         "We want to get closer to our customers and provide them with the
services they need," McArdle said. "In this new era of gas marketing, we believe
more direct interaction between producers and consumers is good for both ends of
the energy chain."

         Apache Corporation is a large oil and gas independent with core
operations in the United States, Canada, Egypt, the United Kingdom North Sea,
and Australia.
