Title:
Bristol Bay and Alaska Peninsula 2004: Fieldwork and sample analyses compilation report
Abstract:
These data are part of a preliminary report based on the 22-day, two-phase, 2004 Bristol Bay-Alaska Peninsula field program. The program's first phase focused on source rock potential of the Mesozoic section, and the second phase focused on reservoir potential and stratigraphic architecture of Tertiary rocks. Data included here are rock sample details, field sample locations, total organic carbon measurements, and porosity and permeability analysis results.

    Date: 2004 (process 1 of 1)
    The first phase of this project included 11 days (May 24 to June 4, 2004) of helicopter-supported fieldwork in the Puale Bay and Wide Bay areas, northeast Alaska Peninsula. The second phase was 11 days (August 23 to September 2, 2004) of helicopter-supported fieldwork in the Port Moller, Herendeen Bay, and Bear Lake area, Bristol Bay. Sample locations were recorded in the field using handheld GPS units. Total organic carbon analyses were performed by Baseline DGSI. Porosity and permeability analyses were performed by Core Laboratories, Inc.
