Apache Reports Horizontal Drilling Successes in Canada's Kaybob Dunvegan Play

HOUSTON, Nov. 20, 2012

HOUSTON, Nov. 20, 2012 /PRNewswire/ --Apache Corporation (NYSE, Nasdaq: APA)
today announced promising drilling results in the Dunvegan oil reservoir in
the Kaybob development area in Alberta, Canada. Kaybob is a prolific area
located 310 miles (500 km) northwest of Calgary that contains 16 known
productive horizons; the Dunvegan play is one of the primary targets.

The most recent of four Kaybob Dunvegan development wells – the 1-35 – tested
at a rate of 300 barrels of oil per day (bopd). The well was drilled to a
vertical depth of 5,700 feet (1,732 meters) with a 4,300-foot (1,319-meter)
lateral and a 13-stage fracture stimulation completion.

The first well in the campaign – the 1-9 – tested at a peak rate of 280 bopd.
It was drilled to a vertical depth of 5,500 feet (1,676 meters) with a
4,900-foot (1,490-meter) lateral and 13 fracture stages.

"These wells were drilled in areas which have been producing for over 40 years
but which have the potential to be completely rejuvenated through the
application of horizontal drilling and multi-stage hydraulic fracturing," said
Tim Wall, president of Apache Canada. "These encouraging results have
contributed to identifying more than 2,000 potential horizontal drilling
locations across our 238,000-acre gross (179,000-acre net) leasehold."

The Dunvegan is a widespread, high quality Upper Cretaceous sandstone
reservoir. A 13-stage horizontal well is expected to recover an estimated
560,000 barrels of oil equivalent. Longer term, the Dunvegan represents a
good candidate for additional production by means of secondary recovery.

"Apache's leading acreage position in the Kaybob area is another example of
the richness of our portfolio," Wall said. "Like other Apache regions, we are
focused on growing through the drill bit in oil- and liquids-rich-gas plays
with a significant backlog of drilling locations in a number of stacked pay
