Cook Inlet Energy likes Osprey sidetrack
Cook Inlet Energy LLC says it’s close to bringing a promising oil well into production on the company’s Osprey offshore platform in the Redoubt unit.
The well is a sidetrack of RU-2, a damaged well originally drilled in 2002.
Casing has been run to a measured depth of 15,265 feet in the sidetrack, known as RU-2A, the company said in a June 12 press release.
“Well log readings from the RU-2A sidetrack indicate a full column of oil throughout the entire Hemlock formation from a measured depth of 14,512 feet to 15,200 feet with permeability, porosity and resistivity equal to or greater than seen in the original RU-2 well,” the company said.
“The new bottom-hole location is 46 feet higher on structure than the original RU-2 and it is conceivable that we will achieve better oil recovery than was previously experienced,” said David Hall, chief executive of Cook Inlet Energy. “Our team will be diligently working to bring the well online within the next several days.”
The RU-2 well has produced about 500,000 barrels of oil to date, and third-party reserve reports show about 950,000 barrels of remaining recoverable reserves from the new well location, the company said.
Two more drilling projects Cook Inlet Energy expects to start drilling its Sword No. 1 well in June. The drill site is next to the company’s producing West McArthur River field.
Sword No. 1 is designed as an extended-reach well to be directionally drilled to 19,000 feet, the company said. It will target probable reserves in an adjacent fault block to the West McArthur River field.
Company-owned 3-D seismic over the prospect area shows a “faulted four-way closure” with a 240-acre structure that contains an estimated recoverable 800,000 barrels of oil, Cook Inlet Energy said.
The company also is preparing to spud a well on its Olsen Creek natural gas prospect. The prospect is west of the ConocoPhillips-operated Beluga River gas field.
“Multiple prospective zones are present within the Olsen Creek prospect area and the planned well will be situated to evaluate the structure. Upon success it is expected that 24 wells would be required to fully develop the field,” the company said.
Based in Anchorage, Cook Inlet Energy is a subsidiary of publicly traded Miller Energy Resources Inc. of Tennessee.
