FROZEN HEAT | Volume 2

Figure 2.6: Within the greater Prudhoe Bay region, two distinct trends of gas hydrate accumulations in sand reservoirs (A; after Collett 1993). Extensive data derived largely from ongoing oil and gas development on the Alaska North Slope has enabled the delineation of the Northern Alaska Gas Hydrate Total Petroleum System (B, after Collett et al. 2008). Sub-permafrost hydrates in the Eileen Trend have been the subject of two collaborative federal-industry scientific field evaluation programs, including the BP-DOE-USGS Mt. Elbert Program in the Milne Pt. Unit (C, Mt. Elbert well site, March 2007; courtesy Mt. Elbert Science Team) and the ConocoPhillips-JOGMEC-DOE Ignik Sikumi program in the Prudhoe Bay Unit (D; Courtesy ConocoPhillips).
