Analysis of the uranium to organic carbon relationship in the organic-rich Ohio Shale of eastern Kentucky
(2020-12)
Organic-rich shales have become increasingly important to unconventional petroleum reservoirs, and tools such as the gamma-ray have been used to locate them due to the radioactivity of elements such as uranium, potassium, ...
Integrated stratigraphic, structural, tectonic, and petroleum systems analysis of the Mississippian Caney Shale, Ardmore Basin, southern Oklahoma
(2021-12)
Burial and thermal history modeling were used to assess the thermal maturity of the Mississippian (Chesterian) Caney Shale in the Ardmore Basin, southern Oklahoma, to determine the formation's viability as an unconventional ...
Removal of oil hydrocarbons from petroleum produced water by indigenous methanogenic oil degrading microbial communities
(2022-12)
Plugging of membrane filters by oil (mostly n-alkanes) constitutes one of the main barriers to treating produced water (PW) for its integration into industrial and agricultural uses. Based on a previous study showing that ...
Isotope chemostratigraphy of the lower Mississippian St. Joe Group in southwestern Missouri and northwestern Arkansas
(2021-07)
The petrography and isotope geochemistry of the St. Joe Group in southwestern Missouri and northwestern Arkansas were analyzed to determine (1) if the positive excursion in the global isotopic curve for delta13C and delta18O ...
Structural framework analysis in the Mississippi Canyon protraction area, Central Gulf of Mexico: Implications for CO₂ sequestration
(2020-07)
Geologic factors such as faults and salt tectonics have implications for the reliability of CO2-Enhanced Oil Recovery (CO₂-EOR) and CO₂ sequestration targets in deep water reservoirs of the Gulf of Mexico. Salt-tectonic ...
Reciprocal characteristics of surface waves: Detecting near surface anomalies
(2020-07)
The dispersive nature of surface waves (different frequencies traveling at different velocities) predominately depends on the subsurface shear-wave properties. The near-surface community takes advantage of this phenomenon ...
Analyzing seasonal variations in benthic foraminifera in Budd Inlet, Puget Sound, Washington, U.S.A.
(2023-05)
Coastal and estuarine pollution has been a growing concern within this century. Benthic foraminifera have been commonly used as a bioindicator for waterway pollution because of their abundance, diversity, and relatively ...
Depositional behaviors of trace metals around hydrothermal vents in the Scotia Sea
(2022-12)
Sediment deposition along the East Scotia Ridge (ESR) in the Southern Oceanis dominated by biogenic sediment due to its location within the diatom belt and is
influenced by the Antarctic Circumpolar Current mainly flowing ...
U-Pb and Hf detrital zircon geochronology and provenance of the Missourian Cottage Grove Sandstone, northern Anadarko Basin, Oklahoma
(2022-05)
The Late Pennsylvanian Cottage Grove Sandstone in the northern Anadarko Basin of northwest Oklahoma is characterized as a series of shallow marine shoals that display reservoir heterogeneity largely driven by detrital ...
Detrital zircon geochronology and provenance analysis of the Desmoinesian (Middle Pennsylvanian) Bartlesville and Red Fork sandstones, Cherokee Platform and Anadarko Basin, Oklahoma
(2020-12)
The Middle Pennsylvanian was a critical time in the evolution of the North American Craton. Tectonic events caused major changes in paleogeography, resulting in the emergence of new sediment sources that changed sediment ...
