(2016-12-16)With the rise in interest of unconventional plays, efforts have moved to understand these formations across 12 orders of magnitude through nm-km scale. Recent work by others has shown the importance of the nanometer range ... -
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 ... -
Depositional Environments, Diagenesis, And Reservoir Delineation Of The FCU 1947 Upper Clear Fork Cored Interval - An SEM Image Analysis Approach To Pore System Characterization
(Environmental & Earth Science, 2014-03-12)Delineating reservoir facies in heterogeneous tidal flat carbonates is a challenge which requires analysis at greater resolutions than wireline logs can provide. Such depositional environments are documented in the upper ... -
Depositional Facies And Reservoir Analysis Of The Tyler Formation In The Central Williston Basin, North Dakota
(Environmental & Earth Science, 2014-07-14)Traditionally, the Pennsylvanian Tyler Formation has been targeted as a conventional reservoir consisting of barrier island and channel sand deposits in the southwestern Williston basin, North Dakota. The purpose of this ... -
Development Of A Mathematical Model, VUMP (Vinasse Utilization For Methane Production)
(Environmental & Earth Science, 2013-07-22)Environmental pollution causes ongoing problems. Many countries are faced with the dilemma of finding alternative energy sources that are cost-effective and environmentally friendly. Biofuels have received much attention ... -
The Effect Of Freshwater Input On δ18o Distribution At The Younger Dryas
(Environmental & Earth Science, 2014-07-14)The Younger Dryas cooling event (~12.9-11.5 δ18O ka BP) is a recognized example of an abrupt decline of the Atlantic meridional overturning circulation and thus may serve as an analog for expected rapid future climate ... -
Effect Of Oil Viscosity Change On Oil Production: CO₂ Enhanced Oil Recovery In The Permian Basin And Potential In The Gabon Basin
With most oil fields around the world reaching maturation it is not uncommon for oil companies to investigate the possibility of implementing CO₂ Enhanced Oil Recovery. The injection of CO₂ in a reservoir reduces the oil ... -
Effects Of Climate Change And Perturbation In Biogeochemical Cycles On Oxygen Distribution And Ocean Acidification
(Environmental & Earth Science, 2014-12)Dissolved oxygen (DO) concentration in the ocean is an important component of the marine biogeochemical cycles. In this study a global oceanic carbon cycle model (HAMOCC 2.0) was used to address how oxygen minimum zones ... -
Enrichment of Volcanogenic Trace Elements in a Continuous Subsurface Eagle Ford Core in South Texas and the Origin of The Oceanic Anoxic Event II at The Cenomanian-Turonian (C/T) Boundary
(2017-12-13)The Upper Cretaceous Eagle Ford Shale of South Texas is a dark grey to black, sporadically laminated, organic rich carbonaceous mud rock located in the subsurface (~13,000), of the hydrocarbon producing shale-oil formation. ... -
Equatorial Pacific Export Production And Carbonate Accumulation Over The Middle Miocene Climate Transition
The Middle Miocene Climate Transition (MMCT) at ~13.8 million years ago (Ma) signifies the point when Earth made its final transition to the icehouse conditions of the Pleistocene. The MMCT is marked by the expansion of ... -
