Title:
Oil and Gas Seeps of the Puale Bay - Becharof Lake - Wide Bay Region, Northern Alaska Peninsula
Abstract:
The east side of the northern Alaska Peninsula near Puale Bay and the Iniskin Peninsula of Lower Cook Inlet have long held interest to exploration geologists due to their well developed oil and gas seeps, which spurred on the first active exploration and drilling efforts for petroleum in Alaska. Several oil rushes occurred in the early part of 20th century, primarily in two phases (1902-1905 and 1922-1926) in the area of Puale Bay and Becharof Lake. Unfortunately all of these wells produced only traces of hydrocarbons. Several subsequent deeper wells were drilled in Mesozoic strata of this region and nearby Wide Bay to the south, but like the earlier efforts, did not prove to be economical. Each oil and gas seep from this region is plotted on the map accompanying this report and their coordinates are listed in a table. Original published information concerning the seeps is reproduced. In addition, a single prominent solid hydrocarbon locality cited in the early literature is also discussed. Geochemical data is given for some of the seeps.

Why was the data set created?

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.

  2. How were the data generated, processed, and modified?

    Date: 2005 (process 1 of 1)
    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. 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 topographic basemap.

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    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.

  2. How accurate are the geographic locations?

    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.

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    This dataset includes coordinates for oil and gas seep localities.

  5. How consistent are the relationships among the observations, including topology?
