Analysis of Modular Dynamic Formation Test Results from the Mount Elbert-01 Stratigraphic Test Well, Milne Point Unit, North Slope Alaska

In February 2007, the U.S. Department of Energy, BP Exploration (Alaska), and the U.S. Geological Survey, collected the first open-hole formation pressure response data in a gas hydrate reservoir (the “Mount Elbert” stratigraphic test well) using Schlumberger’s Modular Dynamics Formation Tester (MDT) wireline tool. As part of an ongoing effort to compare the world’s leading gas hydrate reservoir simulators, an international group conducted history matches of one 12-hour test that included an initial stage of pressure drawdown and response in which pressures were maintained above the level where gas hydrate dissociation would occur; a second stage with 15 min of flow and 97 min buildup that included gas hydrate dissociation and gas production; and Proceedings of the 6th International Conference on Gas Hydrates (ICGH 2008), Vancouver, British Columbia, CANADA, July 6-10, 2008.
