Lithostratigraphy and conodont biostratigraphy of the Upper Boone Group and Mayes Group in the southwestern Ozarks of Oklahoma, Missouri, Kansas, and Arkansas
(2017-05)
Upper Boone Group (Meramecian) and Mayes Group (latest Meramecian-Chesterian) strata exposed across the southwestern Ozarks of northeastern Oklahoma, southwestern Missouri, southeastern Kansas, and northwestern Arkansas ...
Chemical and physical controls of toxic metals removal from petroleum produced water by dolomite filtration
(2023-05)
Produced water (PW) from oil and gas reservoirs contains orders of magnitude higher concentrations of toxic metals (heavy metals, metalloids, and alkaline earth metals) than seawater, shallow groundwater, and conventional ...
Role of pre-existing Precambrian structures and thermal anomaly in rift initiation and evolution - The Albertine and Rhino Grabens in Uganda
(2016-05)
We integrated Shuttle Radar Topography Mission Digital Elevation Models, airborne magnetic, radiometric, three-dimensional Full Tensor Gravity Gradiometry and Satellite gravity data to investigate the role of Precambrian ...
Geochemical evaluation of the Mississippian Limestone
(2020-12)
A multi-proxy geochemical investigation of the Mississippian Limestone interval in the STACK resource play area of the Anadarko Shelf was undertaken, in order to evaluate environmental conditions during deposition of ...
Influence of particle size, microfractures, and moisture content on the permeability of crushed shale samples
(2018-07)
Permeability, porosity and pore size distribution in shale are essential for the evaluation and optimization of hydrocarbon recovery. The absence of standardized procedures for measuring permeability is thought to result ...
Fault structure of the Punta Montalva Fault using high-resolution DEMs
(2022-07)
The Punta Montalva Fault is an active left-lateral strike-slip fault that slipped during the 2019-2020 Puerto Rico seismic sequence. Not much is known about the structure, segmentation, and spatial extent of the fault as ...
New stochastic pore-scale simulation and machine learning approach to predicting permeability and tortuosity of heterogeneous porous media
(2023-05)
A new 3D stochastic pore-scale simulation approach was introduced in this study to investigate how stochastic pore connectivity impacts the permeability and hydraulic tortuosity of heterogeneous porous media. Multiple ...
Morpho-tectonic analysis of the East African Rift System
(2018-07)
Tectonic uplift of mountain ranges and plateaus have a significant impact on the geological record by influencing drainage systems and sediment supply, and on climate and on biogeography. Recent geomorphological, ...
Regional diagenesis of Mississippian strata of the southern mid-continent, USA
(2016-12)
Mississippian carbonates are one of the most complex and largest resource plays on the southern Midcontinent. This study involves petrographic, geochemical, and fluid inclusion analysis of fracture, breccia, vug, and inter- ...
geophysical characterizations of glacial aquifers and earth-fill dams
(2022-05)
Geophysical investigations of groundwater aquifers and earth-fill dams have gained vast attention during the past few decades. Exploring new groundwater aquifers is always essential to meet the growing need for water ...
