This collection is comprised of oil- and gas-related well cores and cuttings from wells drilled to either test for the presence of liquid or gas fossil fuels, examine subsurface stratigraphy and structures, or to produce liquid or gas fossil fuels. All well data in the Geologic Materials Center (GMC) database represents both exploration and production wells. Core has been donated by oil and gas exploration companies as well as state and federal agencies.
This oil & gas related sample collection includes core, core chip, side wall core, cuttings, and unwashed cutting samples as well as oil and gas related surface and shot-hole samples.
A major effort to migrate this data to a web accessible format is supported by a multi-year funding from the Minerals Data and Information at Risk In Alaska Program, a federal program administered by the U.S. Geological Survey and U.S. Bureau of Land Management, and authorized by Congress for five years by the U.S. Congress in 1997.
