Worldwide Petroleum Consultants, (NSAI), www.netherlandsewell.com , to evaluate the prospective resources in their shale acreage on the North Slope of Alaska. Using available data from existing wellbore penetrations and analog shale plays, they determined that the acreage is a qualified Prospective Resource with an average recovery rate of 3,995 barrels of oil per acre from the combined shale intervals.
