88 Energy Ltd., Perth, received its first independently assessed estimate of prospective resources at Project Icewine East on the North Slope of Alaska
US-based firm Lee Keeling & Associates Inc. estimated 1.03 billion bbl of oil recoverable from multiple reservoir zones. The figure is for gross mean unrisked oil in the prospect area.
88 Energy said prospective resources have been estimated across all the recently mapped Shelf Margin Delta, Slope Fan System, Basin Floor Fan, and Kuparuk play fairways on the company’s Icewine East acreage.
All are mapped as the same Brookian-Beaufortian reservoirs from which the nearby Pantheon wells (Alkaid-1, Talitha-A, Theta West-1) flowed 35-40 degree API oil, derisking the Icewine East acreage, 88 Energy said.
The initial total prospective resource estimate follows a period of data review, including seismic from the recently leased Frankin Bluffs 3D data set, well logs from Icewine-1 and wells adjacent to the Icewine East acreage, recent petrophysical analysis, and mapping.
Full interpretation of the Frankin Bluffs seismic is ongoing, including AVO analysis in a bid to define sweet spots for each play and determine future exploration and appraisal well locations, the company said. First wells are planned for 2023.
Project Icewine, on the central North Slope, has been divided into East and West sectors.
Icewine West was independently assessed as having total gross mean unrisked prospective resource of 1.77 billion boe. 88 Energy’s Charlie-1 discovery well drilled in early 2020 recovered hydrocarbons during wireline operations.
With Icewine East, total acreage is estimated to hold 2.8 billion boe prospective resource.
88 Energy holds 75.227% working interest in the project.
