SENSITIVITY OF OXYGEN MINIMUM ZONES DUE TO CARBON DIOXIDE RADIATIVE FORCING USING CESM 1.2
(2019-04-25)Anthropogenic-induced climate change is occurring at an unprecedented rapid rate, compared to the geologic past. In this study, CO2 stabilization scenarios (1x, 2x, and 4x preindustrial atmospheric pCO2 levels) utilizing ... -
Nano-petrophysics study of Haynesville Shale, East Texas, USA
(2019-05-14)As one of the most productive shale gas plays, the Haynesville Shale has a high geopressure gradient and high temperature, but with a lack of petrophysical understanding. To analyze the pore geometry and wettability ... -
Characterizing the nature of the sub-continental lithospheric mantle beneath Prindle volcano, Yukon-Tanana Upland, Alaska
(2019-05-08)Prindle Volcano, an isolated alkali-basaltic cone in eastern Alaska is the northernmost volcanic center within the northern Cordilleran volcanic province (NCVP), a volcanic region along the northwestern region of North ... -
Observations on the magnetic iron oxide content of particulate matter in the Sahel
(2019-05-06)Atmospheric dust influences many processes throughout the biosphere, hydrosphere, and atmosphere, most notably the climate, marine productivity, and human health. Recognizing the physicochemical characteristics of dust ... -
Nano-petrophysics of the Marcellus Formation in Pennsylvania, USA
(2019-05-07)Characterizing unconventional shale reservoirs consisting of nano-size pores and pore networks are complicated due to their complex geometric structure and restrictive fluid transport abilities. Technological advancements ... -
Nano-Petrophysical Properties of the Bone Spring and the Wolfcamp Formation in the Delaware Basin, New Mexico, USA.
(2019-05-09)The Permian Basin is one of the largest oil producing basins in the United States. The Permian Basin is 260 miles by 300 miles in area and encompasses 52 counties in southeast New Mexico and West Texas. In the past decade, ... -
Climate Change of the South Polar Region in response to topographic and cryospheric forcings during the Paleocene-Eocene thermal maximum
(2019-05-03)The Paleocene-Eocene thermal maximum (PETM) occurred approximately 56 Ma and is marked by an estimated global temperature increase of 5 °C, a large negative carbon and oxygen excursion, and deep-sea carbonate dissolution. ... -
History-matching and Forecasting of Three Unconventional Oil and Gas Reservoirs Using Decline Analyses and Type Curves
(2019-05-10)Reservoir modeling of shale gas and tight oil presents numerous challenges due to complicated transport mechanisms and the existence of fracture networks. Even then, oil and gas companies have not slowed down on shale ... -
NANO-PETROPHYSICS OF AVALON SHALE OF THE DELAWARE BASIN OF WEST TEXAS & SOUTHEASTERN NEW MEXICO
(2019-01-17)The Avalon Shale is a Permian-aged stratum and represents a significant rock unit within the Bone Spring, of the Delaware basin of West Texas and Southeastern New Mexico. The Delaware Basin has witnessed increased drilling ... -
Coupled Geochemical and Nano-Petrophysical Study of the Utica Play, Appalachian Basin, Ohio, U.S.A.
(2017-11-29)Being more extensive than the Marcellus Play, the Utica Play covers from New York state in the north to northeastern Kentucky and Tennessee in the south. The Utica Play is a stacked play consisting of organic-rich mudstones ... -
GLOBAL MARINE CARBON EXPORT PRODUCTION DURING EOCENE HYPERTHERMAL EVENTS
(2017-12-20)Early Eocene hyperthermal events can be an analog for global warming. Pelagic marine barite in deep sea sediment is a proxy for marine export production of organic matter into the deep ocean. Pelagic marine barite accumulation ... -
REMOVAL OF PERFLUOROOCTANOIC ACID USING ZEROVALENT IRON BASED MATERIALS
(2018-09-12)Perfluorinated alkyl substances (PFASs) are highly persistent organic contaminants that have become a global health concern. Few studies so far have demonstrated successful decomposition of PFASs under ambient condition. ... -
