The Alaska Department of Natural Resources’ Division of Geological & Geophysical Surveys released new information on the geology of the Alaska Peninsula and Bristol Bay area, Preliminary Interpretive Report 2005-4, on July 21.
Division deputy director Bob Swenson said the data contained in the report will be very useful for companies evaluating prospects for the lease sale.
“This report provides the best source yet of public information about the geologic history, detailed stratigraphic analysis, and hydrocarbon potential of this region” Swenson said in a media release today.
The division said the report draws on data from existing wells, seismic surveys and field mapping performed by geologists from DNR. The U.S. Geological Survey, the university and industry.
The report includes information about the region’s geology, organic geochemistry, sedimentology, and characterizations of significant rock formations. It also includes preliminary subsurface interpretations based on publicly available seismic data.
Copies of the preliminary interpretive report are available on DGGS’s Web site at http://www.dggs.dnr.state.ak.us/
The Division of Oil and Gas issued a preliminary best interest finding for the Alaska Peninsula areawide oil and gas lease sale in February; a final finding is scheduled to be released in August. The sale would be held in October in conjunction with the state’s North Slope and Beaufort Sea areawide lease sales.
Oil was discovered near Puale Bay in 1902 and 26 wells have been drilled on the Alaska Peninsula since 1903, the latest in 1985.
