Anadarko plans more west side Cook Inlet wells
Anadarko Petroleum Corp. is planning a fall 2000 drilling season on the west side of Cook Inlet, with work slated to run from September through November. The company has begun permitting for two wells on the west side of Cook Inlet, the 3 Lone Creek and a re-entry of the 1 Mobil Moquawkie well. Permitting for an additional well, the 2 Lone Creek, was begun in 1998.
The wells are on Tyonek Land, Cook Inlet Region Inc. subsurface, on the western side of Cook Inlet. Site access for the locations originates at the existing Tyonek Village Road system and uses the proposed access road to the 2 Lone Creek site. No more than 1,000 feet of new road to each location will be required.
In October 1998, Anadarko and partner ARCO Alaska Inc. announced a gas discovery at the 1 Lone Creek. The well flowed 10.6 million cubic feet of natural gas per day through a 33/64-inch choke with 925 psi flowing tubing pressure from 53 feet of perforations at approximately 2,400 feet.
"This represents one of the best shallow gas tests in the vicinity for a reservoir of this age and type," Anadarko said in 1998. The company also said several other possible gas zones, approximately 180 feet, were encountered during drilling but were not tested and that plans to develop the find "may include additional drilling and installation of facilities necessary to produce this and subsequent wells. The well is located within five miles of a 16-inch natural gas pipeline."
Anadarko said in its July permit applications that work would begin at the 2 Lone Creek, the most northerly location, then move to the 3 Lone Creek and then to a re-entry at the 1 Mobil Moquawkie, drilled in 1965.
