BRPC to case, test Sak River 1-A well
Brooks Range Petroleum Corp. is planning a production flow test on a North Slope exploration well after encountering hydrocarbons, the company announced on Feb. 17.
BRPC, which is operating a multiwell program this winter on behalf of several partners, drilled the Sak River No. 1-A sidetrack to a measured depth of 12,726 feet and a total depth of 9,350 feet, “stopping within the Miluveach formation.” In a statement, BRPC said, “Porous sandstones with hydrocarbon shows were encountered in sandstones of the Kuparuk formation at a depth of approximately 8,900 feet subsea (total vertical depth).”
Sak River No. 1-A is in the onshore-offshore Beechey Point unit in the Gwydyr Bay area. BRPC drilled the well from an onshore ice pad to bottomhole location more than a mile and half offshore beneath Gwydyr Bay. BRPC drilled the well using Nabors rig 16 E.
Sidetrack spud in January The company spud Sak River No. 1-A on Jan. 26.
BRPC said it decided to case the well and begin testing because a Modular Formation Dynamics Tester — a wireline tool used to measure pressure and permeability and to take fluid samples — “failed to recover a reservoir sample due to a tool failure.”
The company said it plans to release results after completing testing operations.
Sak River No. 1-A is a sidetrack of a well BRPC drilled in 2007 to a total depth of 11,348 feet and a measured depth of 13,110 feet. That well did not encounter any hydrocarbons.
BRPC is an affiliate of the Alaska Venture Capital Group, and operates on behalf of the BRPC Group, which includes TG World Energy Inc. and Ramshorn Investments Inc.
