INVESTIGATION OF GAS HYDRATE-BEARING SANDSTONE RESERVOIRS AT THE "MOUNT ELBERT" STRATIGRAPHIC TEST WELL, MILNE POINT, ALASKA
In February 2007, the U.S. Department of Energy, BP Exploration (Alaska), Inc., and the U.S. Geological Survey conducted an extensive data collection effort at the "Mount Elbert #1" gas hydrates stratigraphic test well on the Alaska North Slope (ANS). The 22-day field program acquired sign...
