SHALE GAS/OIL RESERVOIR CHARACTERIZATION AND MATURITY DETERMINATION BASED ON VARIOUS EXPERIMENTAL ANALYSES
(2019-05-31)Despite the successful shale hydrocarbon exploration and production in the U.S. started about 20 years ago, the producing wells experience a current low total recovery of tight oil (5%-10%) and shale gas (12%-30%). One of ... -
Community Ecology and Population Dynamics of the Nearshore Marine Fauna in the Middle Atlantic Bight (USA)
(2019-05-06)Natural resources are among the most valuable commodities on earth. Some natural resources (air, land, and water) are essential for human survival and many often constitute a large percentage of local, regional, and national ... -
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. ... -
BENEFITS AND OBSTACLES TO INSTALLING WIND AND SOLAR ENERGY SYSTEMS ON UNIVERSITY CAMPUSES: A TEXAS STUDY
(2018-08-13)There is much known about renewable energy including solar and wind. However, there is little information available regarding the use of wind and solar energy on college and university campuses. As educators and shapers ... -
The Negative Impacts of Lead- Contaminated Superfund Sites and the Toxicological Effects on Children in Dallas County
(2018-06-11)This Study was conducted to investigate the toxicological effects of lead on children, from the age of 0 years old to 18 years old, that reside or attend schools, located within the 5-mile radius, of lead contaminated ... -
A MODERN RESERVOIR ANALOG FOR A POORLY DRAINED “HIGH ACCOMMODATION” FLUVIAL SYSTEM: SEDIMENTARY PROCESSES, ARCHITECTURE, AND RESERVOIR CONNECTIVITY OF THE GRIJALVA SYSTEM, TABASCO STATE, MEXICO
(2016-09-12)High-accommodation fluvial systems are subject to much modeling and substantial rock drilling and imagination, but limited modern field observation. The Grijalva River system of Tabasco State, Mexico offers the opportunity ... -
Tectonic processes and continental hydroclimate during the Laramide deformation in the central Rocky Mountains
(2017-05-12)The central Rocky Mountains in western U.S.A. is a geologic province formed by the low-angle subduction of the Farallon oceanic plate under the North American continental plate during the latest Cretaceous–early Eocene ... -
Motion And Rigidity Of The Caribbean Plate And Geodetic Observations Of Dominica, Lesser Antilles
The currently accepted kinematic model of the Caribbean plate presented by DeMets et al. (2007), is based on velocities from 6 continuous and 14 campaign GPS sites. This work attempts to refine the current plate model by ... -
IMPLICATIONS OF LITHOFACIES ASSOCIATION AND ARCHITECTURE FOR LOW AND HIGH-ACCOMMODATION SYSTEM TRACTS FROM THE SANDSTONE DOMINATED ZONE ( THE BARREN SERIES) OF THE CRETACEOUS-PALEOCENE RATON FORMATION, TRINIDAD, COLORADO
(2017-01-02)The Raton Formation is an Upper Cretaceous and Lower Paleocene unit that is interpreted to be deposited in various stages of high-accommodation fluvial systems. High-accommodation flood basin deposits are generally considered ... -
Sensitivity of the Younger Dryas climate to changes in freshwater, orbital, and greenhouse gas forcing in comprehensive climate models
(2016-05-11)The Younger Dryas cooling event (~12,900 years before present) was the most recent abrupt climate change in the geologic record where climate for the Northern Hemisphere returned to a near-glacial state. The cause of this ... -
Identifying Source of Lead Particles in Floor Dust Using Computer Controlled Scanning Electron Microscope (CCSEM)
(2016-05-10)Identifying the sources of lead (Pb) in indoor dust by analysis of the contents of the dust provides an opportunity to mitigate the source of contamination. In this study, it is hypothesized that in residential properties ... -
A Multiphysics Approach: Thermodynamics, Material Mechanics And Fluid Dynamics Of Magma Systems At Active Volcanic Regions
Understanding the genesis, incubation, evolution and equilibration of silicic magma reservoirs that drive and source volcanic activity all over the planet is fundamental to the discipline of geology. The subsurface processes ... -
Predicting Variability Of Basal Scour And Quantifying Vertical Connectivity For Channel-belt Reservoirs Using Observations From The Holocene Mississippi River And Channel-belt
Assessment of potential for draining unpenetrated but closely stacked channel-belt reservoirs from an existing belt penetration depends upon an understanding of the methods of and the likelihood for connectivity between ... -
Spatio-temporal Variations In Asthma Hospitalizations In Texas 2005-2011 By County And Possible Association With Ozone Exposure
Texas asthma hospitalization data at the county level has been reviewed for the period 2005-2011. Exploratory data analysis revealed a general countywide reduction in the number of hospitalizations over this time period. ... -
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 ... -
Sensitivity Of The Late Permian Climate To Tectonic And Radiative Forcing Changes: Implications For The Mass Extinction
(Environmental & Earth Science, 2014-12)The largest mass extinction occurred near the Permian-Triassic boundary (ca. 252 Ma). Significant carbon isotope shifts indicate that perturbations in the carbon cycle occurred during the Late Permian and persisted into ... -
Application Of In-situ Remediation By Using Soil Phosphate Amendments At Three Lead Contaminated Soil Sites (residential Yards) In New Orleans, La.
(Environmental & Earth Science, 2014-12)Lead (Pb) contamination of soil continues as a threat to public health. The problem exists, in part, due to the abundance of lead in soil in certain contexts which has the potential to cause adverse health effects in ... -
