(2012-07-16)Many scientific studies have been conducted on the Cretaceous-Paleogene boundary (KTB) in the Gulf coast region and, in particular, the Brazos River section in Falls County, Texas. Despite this, there remains much to be ...
-
(2010-01-14)Pointe du Hoc overlooking the English Channel in Normandy, France was host to one of the most important military engagements of World War II. While the site is a valuable historic cultural resource, it is vulnerable to ...
-
(Texas A&M University, 2004-09-30)In this study, the structure, depositional system, and the seismic stratigraphy of the VLE 196 area, Block V in Lamar Field were interpreted using 3-D seismic data and well logs to characterize structural and depositional ...
-
(Texas A&M University, 2007-09-17)Relatively little is known about marine controlled-source electromagnetic surveys (MCSEM) used to detect hydrocarbon reservoirs. Typical MCSEM require the use of inversion to generate a model of the subsurface. We utilize ...
-
(2012-02-14)The date for the formation of the Benton Uplift, Ouachita orogeny, is bracketed by Carboniferous synorogenic sediments deposited to the north and Late Pennsylvanian to Early Permian isotopic dates from the weakly metamorphosed ...
-
(2022-04-18)Reservoirs in the Arabian Gulf, home to some of the world’s largest oil reserves, consist primarily of heterogeneous carbonate rocks and successfully recovering hydrocarbons from them is a challenge. With existing technologies, ...
-
(2021-12-16)The coupled processes of biogeochemical and hydrological processes in hyporheic zones (HZ) commonly determine the fate of contaminants in both groundwater and surface water. Many parts of the HZ experience both transient ...
-
(2023-04-21)Utilizing aquifer thermal energy storage and recovery systems (ATES) and groundwater heat pumps (GWHP) for seasonal space heating and cooling in public and commercial spaces is one solution to reduce fossil fuel consumption ...
-
(2017-04-27)Understanding how the climate of the North American Great Plains may change in the future is of tremendous socioeconomic importance, yet the regional response to previous abrupt global climate events, such as the ...
-
(2011-10-21)A range of geochemical reactions are controlled by the interfacial characteristics of rocks and minerals. Many engineered and natural systems are affected by geochemical reactions that occur at interfaces. Asphalt-aggregate ...
-
(2012-07-16)Windblown dust is a significant source of sediment and organic matter for many basins, but its influence on ancient basins can be difficult to detect and quantify. We quantified the biomarker content, including n-alkanes, ...
-
(Texas A&M University, 2007-04-25)The landfall of hurricane Claudette in 2003 damaged and eroded most Texas coastal counties. The residents of Pointe San Luis on the west end of Galveston Island, Texas lost their protective dune front and experienced ...
-
(2018-11-16)The Allende-Piedras Negras (APN) aquifer is located between the state of Texas (USA) and the state of Coahuila (Mexico). The Rio Grande/Rio Bravo crosses the aquifer acting as a natural and political divide between both ...
-
(2017-12-08)The Deepwater Horizon Oil Spill in 2010 released approximately 5 million barrels of oil into the Gulf of Mexico just as the nearshore and beach profile were recovering from winter storms. As a consequence, oil mats and tar ...
-
(Texas A&M University, 2008-10-10)The Winland R35 method [Log R35 = 0.732 + 0.588 (Log Kair) 0.864 (Log O)] is based on the relationship between porosity, permeability, and pore throat radius at the point of 35% mercury saturation in capillary pressure ...
-
(Texas A&M University, 2007-04-25)A detailed investigation of cores from three Peru Margin sites drilled during Ocean Drilling Program (ODP) Leg 201 has been conducted to determine the occurrence of volcanic ash layers and ash accumulations within marine ...
-
(2020-04-16)There are over three-million abandoned oil and gas wells in the U.S., the majority of them are unplugged and unrecorded according to an estimation of US Environmental Protection Agency (U.S. EPA). If the abandoned wells ...
-
(2015-05-13)The quality of the seismic data is essential to quantitative reservoir characterization of rock properties and geological structure interpretation. Although marine multi-component seismic data hold a wealth of information ...
-
(2010-07-14)As human population increases, demand for water supplies will cause an increase in pumping rates from confined aquifers which may become unconfined after long-term pumping. Such an unconfined-confined conversion problem ...
-
(2013-02-06)Mountain areas are prime locations for mass movement activity, as a result of their steep slopes and large amount of local relief. As a rapid mass movement phenomena, landslides are responsible for a considerable numbers ...
