                   APACHE, AMERADA HESS ANNOUNCE TRANSACTIONS
                             IN EGYPT, PERMIAN BASIN


         HOUSTON, Oct. 13, 2005 -- Apache Corporation (NYSE, Nasdaq: APA) today
said that it has agreed to sell its 55 percent interest in the deepwater section
of Egypt's West Mediterranean Concession to Amerada Hess Corporation for $413
million. Apache also has agreed to purchase Amerada Hess's interests in eight
fields located in the Permian Basin of West Texas and New Mexico, six of which
are operated, for $404 million.

         The Permian Basin transaction is subject to exercise of preferential
rights as well as standard closing requirements.

         Apache President and Chief Executive Officer G. Steven Farris said,
"Apache intends to concentrate and continue its rapid growth in Egypt's Western
Desert. Egypt has been good to us and we welcome Amerada Hess as a strong and
growing company.

         "We are also pleased to add to Apache's present production and position
in the Permian Basin. The concurrent sale of our unbooked West Mediterranean
reserves enables us to expand and accelerate our production base in the United
States," Farris said.

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