Stratigraphic and depositional controls on source rock heterogeneity and composition of expelled petroleum in the triassic shublik formation of Arctic Alaska
Abstract/Contents
- Abstract
- Petroleum source rocks display significant variability in lithology, and quality, quantity and thermal maturity of organic matter. However, many regional geochemical studies focus on a few selected rock samples that may not represent the entire source rock section, which can affect estimates of resource potential assessment (conventional and unconventional). For nearly thirty years, the Triassic marine carbonate Shublik Formation has been suggested and confirmed as a key source rock for hydrocarbons in the North Slope of Alaska. The formation accounts for roughly one third of the oil in the supergiant Prudhoe Bay Field, and for nearly all of the oil in the second largest Kuparuk River Field. This dissertation examines oil-source rock correlation, source rock heterogeneity, distribution of organic-rich and -lean intervals, and evidence for migrated hydrocarbons in a stratigraphic framework with implications for unconventional shale resources evaluation. While different workers have conducted lithostratigraphic analysis of the Shublik Formation, and geochemical analyses of North Slope oils, this work links geochemistry, sedimentology, and petroleum system analysis, providing detailed shale resource system evaluation, which ultimately contributes to the growing body of knowledge in such exploration frontiers.
