Biostratigraphic Analysis of Northwestern Alaska Peninsula Bristol Bay Basin Exploration Wells
The Alaska Department of Natural Resources, through both the Division of Oil and Gas (DOG) and the Division of Geological and Geophysical Surveys (DGGS), completed technical studies in preparation for the areawide lease sale offering of state acreage on the Alaska Peninsula in October, 2005. The offering is the first state lease sale in the region since 1985. DOG is committed to assembling and publicly distributing as much geological and geophysical data and interpretation as possible as a means of renewing petroleum industry interest in this under explored area. For example, in January, 2004, DOG released to the public an extensive compilation of digital information, including geologic maps, well logs, and seismic data free of charge in a three-volume set on compact disk.
In order to better define the regional stratigraphic and structural framework of the Tertiary-aged Bristol Bay Basin (also known as North Aleutian Basin) in advance of the proposed lease sale, DOG contracted with Micropaleo Consultants for professional services to complete a biostratigraphic analysis already in progress of 11 key exploration wells, representing both onshore and offshore penetrations of the basin. The data and interpretations are provided in both fully digital and hardcopy formats.
