Apache logs 43 ft net pay off Australia
Offshore staff
HOUSTON -- Apache Corp.'s Julimar Northwest-1 exploration well on Australia's Northwest Shelf logged 43 ft (13 m) of net pay in the J-17 Triassic Mungaroo sandstone.
"Apache has now drilled six successful exploration wells on permit WA-356-P, validating the geophysical techniques used to identify natural gas-bearing stratigraphic traps," says G. Steven Farris, Apache's president and CEO. "We are planning to drill three additional wells on the block during 2008.
"This latest well further strengthens our belief that the ultimate size of this gas accumulation is in the range of 2 to 4 tcf," Farris said.
The J-17 sand also is present in the Julimar-1 discovery well two miles to the southeast. Julimar-1 encountered 132 ft (40 m) of net pay in four zones, including 42 ft (13 m) in the J-17 sand.
Seismic, log, and pressure data indicate that the J-17 gas pay in Julimar Northwest-1 communicates with and connects to the upper pay zone in Julimar-1 and Julimar East-1, which is four miles from the latest well, says Apache. The average porosity and permeability of the gas pay intersected in Julimar Northwest-1 is of higher quality than the equivalent zone in Julimar-1, which tested at an equipment-limited rate of 42 MMcf of gas and 627 b/d of condensate.
The Julimar-1 tested a total of 85 MMcf/d from two zones.
Apache owns a 65% interest in the 239,440-acre block; Kufpec owns the remaining interest.
