In light of the upcoming oil and gas lease sale in the Bristol Bay region October 26, 2005, the Alaska Division of Geological & Geophysical Surveys (DGGS) is undertaking an assessment of possible oil- and gas-bearing rocks on the Alaska Peninsula. Due to the renewed interest in this region, it was deemed necessary to compile a detailed listing of all proven oil and gas seeps in the area of Puale Bay, Becharof Lake, and Wide Bay, and plot their occurrences on a modern map base for use by petroleum explorationists.

Localities and coordinates listed herein were often determined from primitive map bases, and thus are often only approximate, due to the primitive nature of the earlier topographic maps used and published in the 1920s. The type of location information used is noted with each occurrence in the accompanying report. Coordinates for the point data were created visually from previously published maps using MapInfo Professional 7.5 and exported into a Microsoft Excel spreadsheet. Geologic data used in this compilation are the data from sources as noted in the "Source_Information" section.
The type of location information used is noted with each occurrence. Coordinates for the point data were created visually from previously published maps using MapInfo Professional 7.5 and exported into an Excel table. Locations were extracted from inch to mile maps, dating back to the 1920s, georeferenced in the ArcMap GIS environment to a 1:250,000-scale topographic basemap. The basemap was generated by stitching together four separate topographic maps using the All-Topo software package. The locations may have an uncertainty of 100 meters or more.
This dataset includes coordinates for oil and gas seep localities.
