            APACHE'S THIRD-QUARTER EARNINGS RISE 57 PERCENT TO RECORD
      $432 MILLION, OR $1.31 PER SHARE, ON STRONG PRICES, RECORD PRODUCTION

      Houston, Oct. 28, 2004 - Apache Corporation (NYSE, Nasdaq: APA) today
reported record third-quarter earnings of $432 million, or $1.31 per diluted
common share, up 57 percent from $276 million, or 84 cents per share in the
prior-year period. The combination of continued strong prices for both oil and
natural gas and record oil production fueled Apache's results.

      Apache's earnings improved 16 percent over the previous record, $372
million or $1.13 per share, which was reported in the second quarter of 2004.
Cash from operations before changes in operating assets and liabilities totaled
a record $883 million in the third quarter, up from $731 million in the
year-earlier period. (This is a non-GAAP measure; see reconciliation below.)

      Apache's third-quarter earnings were reduced by 6 cents per share because
of the impact of foreign currency swings on deferred taxes and by 4 cents per
share because production was curtailed by Hurricane Ivan.

      Apache's worldwide daily production averaged 458,412 barrels of oil
equivalent during the third quarter, up 2 percent from the prior-year period.
Liquid hydrocarbon production averaged 252,800 barrels per day, up 6 percent
from the prior-year period and an 8 percent increase from the second quarter of
2004. Higher production in Australia, the North Sea and



China more than offset the impact of Hurricane Ivan, which reduced Apache's U.S.
oil production by 4,042 barrels per day during the quarter.

      Natural gas production averaged 1.23 billion cubic feet (Bcf) per day,
down about 30 million cubic feet (MMcf) per day from the prior-year period, and
about 20 MMcf below the second quarter level. Gas production would have been
above second-quarter levels had it not been for the impact of Hurricane Ivan.

      In the third quarter, production from the Forties Field in the United
Kingdom sector of the North Sea averaged 58,000 barrels of oil per day, up from
47,200 barrels per day in the second quarter, while oil production in Australia
averaged 32,200 barrels per day, up 45 percent from the second quarter. Apache's
share of production from the Zhao Dong block in Bohai Bay, China, rose to 7,900
barrels per day, up 32 percent from the second quarter.

      "Apache established a new production record despite the negative effects
of Hurricane Ivan," said G. Steven Farris, president, chief executive officer
and chief operating officer. "What made the difference was growth in other
regions, including a 23 percent increase in production from the North Sea."

      Apache has drilled approximately 1,500 wells in the first three quarters
of 2004.

      "With the impact of our recently completed acquisitions in the Permian
Basin and the Gulf of Mexico, coupled with our active drilling program, we have
great momentum going into the fourth quarter and into 2005," Farris said.

      Commodity prices remained strong in the third quarter. Apache received
$38.04 per barrel of oil during the third quarter, up 39 percent from $27.34 in
the prior-year period; $26.94 per barrel for natural gas liquids, compared with
$18.99 per barrel, and $4.77 per thousand cubic feet (Mcf) of gas, compared with
$4.45 per Mcf.



      Apache's debt-to-capitalization ratio rose slightly to 26.3 percent at the
end of the quarter, from 23.2 percent at the end of the second quarter, because
of the cost of assets purchased from ExxonMobil and Anadarko Petroleum.

      Apache Corporation is a large oil and gas 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.
