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 ... -
Experimental and theoretical studies of fluid-solid coupling processes of tight rock media
(2023-08-24)**Please note that the full text is embargoed until 8/1/2025** ABSTRACT: This study covers the application of continuum mechanics in the realm of rock work in geological studies. Continuum mechanics encompasses two major ... -
EXPERIMENTAL CONSTRAINTS ON THE MICROMECHANICS OF BRITTLE FRAGMENTATION DURING EARTHQUAKE RUPTURE
(2016-12-09)Various fault damage fabrics, from gouge in the principal slip zone, to fragmented and pulverized rocks in the fault damage zone, have been attributed to brittle deformation at high strain rates during earthquake rupture. ... -
Experimental Studies On Shrinkage Induced Pressure Measurements Of Four Expansive Soils
(Civil & Environmental Engineering, 2011-03-03)Civil structures were damaged by expansive soils due to its large volumetric changes caused by moisture fluctuations. During wet and dry season, the ground heaves up and also shrinks noticeably. The significant amount of ... -
Facies-Based and Anhydrite-Controlled Petrophysical Properties of the upper Clear Fork Formation in the Permian Basin in West Texas, USA
(2020-05-13)The Leonardian-aged dolomite of the upper Clear Fork Formation in the Palm Sunday field of West Texas exhibits a wide range of facies that vary during deposition due to environmental factors such as water depth, wave energy, ... -
FACTORS ASSOCIATED WITH ADULT ASTHMA RELATED EMERGENCY ROOM DISCHARGES IN NORTH CENTRAL TEXAS IN 2010 - 2014
(2019-12-06)Asthma is a common chronic disease of the airways characterized by recurrent reversible airway obstruction. More than 25 million Americans have asthma. In this study, factors associated with adult asthma related emergency ... -
FLUID UPTAKE OF THE GODDARD SHALE IN SOUTHEASTERN OKLAHOMA, USA
(2015-12-07)The South Central Oklahoma Oil Province is the current play for the Goddard shale and is also the main field for the underlying Woodford Formation. As of September 2015, an estimated 40 wells have been drilled to evaluate ... -
Fluvial Architecture And Geometry Of The Mungaroo Formation of Rankin Trend on the Northwest Shelf of Australia
(Geology, 2010-07-19)The Northwest Shelf of Australia contains many producing world class gas reservoirs with large areas remaining unexplored. The fluvio-deltaic Mungaroo Formation of Rankin Trend on the Northwest Shelf is the site of many ... -
Foraminifers Of The Clarita Formation (Wenlock, Silurian), From The Arbuckle Mountains, Oklahoma
(Geology, 2014-12)The study, identification, and classification of Silurian foraminifers from the Arbuckle Mountains in Oklahoma have attracted little attention since the work of Moreman and Ireland in late 1930's. These authors described ... -
The Formation And Obduction Of Ophiolites Since The Late Precambrian
(Geology, 2007-08-23)Ophiolite formation and emplacement has been episodic since the Late Precambrian. This research study examines ophiolites that formed during the Cenozoic, Mesozoic, Paleozoic and Late Precambrian. The ophiolites were ... -
FRACTURE DENSITY AND BRITTLENESS OF THE MESOZOIC FORMATIONS EXPOSED ON THE CANADIAN ESCARPMENT OF EASTERN NEW MEXICO
(2018-07-02)Production of hydrocarbons from tight and unconventional reservoirs has become so prevalent, the need to understand rock fracture mechanics has become increasingly important. A specific research goal is the need to understand ... -
Fracture Density Of Units In The Brushy Canyon Formation, Whitehorse Group And Winchell Formation Of The Permian Basin.
