Discovered in 1965, this non-unitized oil pool is located on the western side of Cook Inlet, about 1/2 to 5 miles offshore. The field lies within a north-northeast trending, asymmetric anticline that is approximately 8 miles long and 1 mile wide. The east flank of the anticline dips about 25 degrees to the east and the west flank dips from 60 to 80 degrees toward the west. To develop the pool, the Anna, Bruce and Granite Point Platforms were installed during 1966 in water ranging from 62 to 77 feet deep. Regular production began in March of 1967, and waterflood was initiated during 1971.
The Granite Point Middle Kenai Oil Pool is defined as the accumulation common to, and correlating with, that found in the Mobil Granite Point No. 1 well between 7,725 and 10,800 feet measured depth. The productive sandstone and congolmerate layers within the pool are assigned to the "C" zone of the lower Tyonek. These layers were deposited in braided streams during the Oligocene to Miocene. Individual reservoir layers vary in thickness from 10 to 100 feet. Net pay for the pool averages about 250 feet. Porosity of the reservoir averages 14 percent, and permeability averages 10 millidarcies. Middle Kenai oil gravity ranges from 41 to 44 degrees API.
