Total organic carbon and pyrolysis analysis data for the Rock Well Petroleum core #8, southern Casper arch, Natrona County, Wyoming

In 2006, Rock Well Petroleum drilled and logged nearly 1,600 feet (ft) of continuous core on the southern part of the Casper arch in Natrona County, Wyoming (see fig1.png). The core hole, named the Poison Spider core #8 penetrated the interval extending from the Upper Cretaceous Frontier Formation to the Triassic Alcova Limestone. The core was subsequently donated to the U.S. Geological Survey Core Research Center (CRC) in Lakewood, Colorado, where it was sampled to evaluate the hydrocarbon source rock potential of the Lower and lowermost Upper Cretaceous marine shales.
