COST WELL NO. GE-1

Download Data

The U.S. Geological Survey recently provided well logs from the COST (Continental Offshore Stratigraphic Test) Well GE-1 to the National Geophysical and Solar-Terrestrial Data Center. These data are now available for public dissemination.

The deep stratigraphic test well was drilled by Ocean Production Company from February 1977 to May 1977, for a group of oil companies to help estimate the petroleum potential of rocks in the Southeast Georgia Embayment before submitting bids for the lease sale in this area. The well was drilled in 136 feet (41 meters) of water to a depth of 13,254 feet (4,040 meters) and revealed potentially good reservoir sandstone and good source rocks in the interval 2,800 to 5,800 feet (853 to 1,768 meters).

DATA PREVIOUSLY MADE AVAILABLE

High-resolution geophysical data were previously announced and made available for this area (Lease Sale 43) by NGDC through NGDC filers 1978 (N). These data included side-scan sonar, fathograms, and sub-bottom profiles. Microfilms of the raw data, interpretative maps, and technical reports are available for dissemination.
