                                           FOR RELEASE AT 7:45 A.M. CENTRAL TIME

              APACHE REPORTS FIRST-QUARTER EARNINGS RISE 62 PERCENT
                       TO $559 MILLION OR $1.67 PER SHARE

         Houston, April 28, 2005 - Apache Corporation (NYSE, Nasdaq: APA) today
reported that higher oil and gas prices and strong production contributed to
record first-quarter 2005 earnings of $559 million or $1.67 per diluted common
share, up from $345 million or $1.05 per diluted common share in the first
quarter of 2004.

         Cash from operations before changes in operating assets and liabilities
totaled $1 billion, up from $737 million in the year-earlier period. (This is a
non-GAAP measure; see reconciliation below.)

         Production averaged 462,000 barrels of oil equivalent per day in the
quarter, up 7 percent from the first quarter of 2004 and up slightly from last
year's fourth quarter.

         High oil and gas prices were a strong driver for first-quarter
financial results. Apache received $46.05 per barrel of oil in the quarter, up
51 percent from the prior-year period; $27.68 per barrel of natural gas liquids,
up 16 percent; and $5.30 per thousand cubic feet of gas, up 11 percent.

         "We are off to a strong start in 2005, with record earnings," said
G. Steven Farris, Apache's president, chief executive officer and chief
operating officer. "Our successful drilling program in the first quarter
and deep inventory of opportunities should contribute to Apache's financial and
operating results in coming quarters."





         Recent operational highlights include:

         o        Apache drilled two significant discoveries in Egypt during the
                  quarter. The Syrah 1X wildcat, on the company's 100
                  percent-contractor-interest Khalda Concession, tested 46.5
                  million cubic feet (MMcf) of natural gas per day. The
                  Tanzanite 1X discovery, located onshore on Apache's 65
                  percent-contractor-interest West Mediterranean Concession, was
                  tested in two separate Alam el Bueib (AEB) zones. The first
                  tested at a rate of 5,296 barrels of oil and 7 MMcf of gas per
                  day and the second at a rate of 5,631 barrels of oil and 17
                  MMcf of gas per day.

         o        Apache has drilled 86 wells on Canadian acreage acquired last
                  year in a farm-in from ExxonMobil. Apache has tested 73 wells
                  with productive capacity of 52 MMcf of gas per day. The wells
                  are expected to be brought on production as processing and
                  transportation infrastructure becomes available.

         o        Apache's debt-to-capitalization ratio declined to 22.7 percent
                  at the end of the first quarter, from 24 percent at year-end
                  2004.

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

NON-GAAP FINANCIAL MEASURES:

The press release discusses Apache's cash from operations before changes in
operating assets and liabilities. It is presented because management believes
the information is useful for investors because it is used internally and widely
accepted by those following the oil and gas industry as a financial indicator of
a company's ability to generate cash to internally fund exploration and
development activities, fund dividend programs, and service debt. It is also
used by research analysts to value and compare oil and gas exploration and
production companies, and is frequently included in published research when
providing investment recommendations. Cash from operations before changes in
operating assets and liabilities, therefore, is an additional measure of
liquidity, but is not a measure of financial performance under GAAP and should
not be considered as an alternative to cash flows from operating, investing, or
financing activities.

The following table reconciles net cash provided by operating activities to cash
from operations before changes in operating assets and liabilities.
