Controlling factors of river water stable isotope compositions and middle to late Cenozoic deposition and surface uplift history of the southern Rocky Mountains, U.S.A.
(2019-09-03)The Cenozoic topographic evolution of the Rocky Mountains (Rockies) and Great Plains in the western U.S.A. reflect a combination of mantle geodynamic, crustal deformation and surface erosional processes. This region was ... -
Variability and Temporal Trends of Semivolatile Organic Compounds in Biological and Environmental Media
(2020-08-28)Exposure to semivolatile organic compounds (SVOCs) in indoor environments and its potential impact on human health have been receiving increased public attention, because people in developed countries spend over 80% of ... -
Investigation of petrophysical properties and fluid migration in unconventional oil/gas reservoirs
(2019-05-07)Petrophysics deals with the physical and chemical properties of petroleum-bearing rocks and their interactions with associated fluids. The investigation of petrophysical properties of interest, such as porosity, specific ... -
NANO-PETROPHYSICS OF THE DEAN, SPRABERRY, AND WOLFCAMP FORMATIONS OF THE MIDLAND BASIN
(2019-05-15)Technological advances in hydraulic fracturing and horizontal drilling have led to a surge in oil and gas production in unconventional shale reservoirs over the past several decades. The Permian Basin of Northwest Texas ... -
TWO CRETACEOUS TALES OF THE LAND AND THE SEA
(2019-05-07)The Cretaceous Period (145-66 Ma), with no magnetic reversal for ~79 Ma, is generally termed as the Cretaceous Normal Superchron or the Magnetic Quiet Zone. There is evidence of at least two major large scale, global ... -
TRACING PALEOZOIC SILICICLASTIC SEDIMENT DISPERSAL TO THE FORT WORTH AND MIDLAND BASINS: IMPLICATIONS FOR PALEOGEOGRAPHY AND ORGANIC MATTER ACCUMULATION
(2019-05-14)The Fort Worth and Midland Basins in central and West Texas are major petroleum-producing systems in North America. The provenances of the thick Paleozoic sedimentary rocks in both basins are poorly constrained, although ... -
THE NORTH CENTRAL TEXAS URBAN HEAT ISLAND MAGNITUDE AND ITS RELATION TO SEVERE AND EXTREME DROUGHT
(2021-05-04)This study focuses on how summer droughts affect the urban heat island (UHI) in Dallas-Fort Worth (DFW). The nocturnal UHI has been computed by comparing downtown temperature observations to rural temperature measurements ... -
Alluvial Fan Deposits of the Todos Santos Formation of Central Chiapas, Mexico
(University of Texas at Arlington Libraries, 1981-07)The Todos Santos Formation at Jerico was deposited as an alluvial fan system by high gradient, short duration ephemeral streams which transported gravel, sand, and mud northeastward through a feeder canyon which opened out ... -
RECOMPILATION OF LITHOLOGICAL PROXIES ACROSS THE PERMIAN-TRIASSIC BOUNDARY
(2020-12-09)The largest mass extinction occurred near the Permian-Triassic boundary (PTB; 251.902 ± 0.024 Ma; Shen et al., 2011), with the demise of more than 90% of marine species and 70% of terrestrial species. This study expands ... -
NANO-PETROPHYSICAL CHARACTERIZATION OF THE OIL WINDOW OF EAGLE FORD SHALE FROM SOUTHWESTERN TO CENTRAL TEXAS, U.S.A.
(2020-08-05)Eagle Ford Shale and the overlying Austin Chalk are the main producing plays throughout Central Texas. Due to the high clastic nature of Eagle Ford Shale and its ability to produce and maintain fractures from hydraulic ... -
GEOSPATIAL ANALYSIS OF POTENTIAL FLOODING FROM STORM SURGE AND SEA-LEVEL CHANGE ON THE TEXAS COAST BY 2100
(2020-05-14)Tropical cyclones pose a major hazard to the State of Texas. Anthropogenic climate change and global warming have the potential to increase extreme weather events and lead to enhanced flood hazard zones. This study aims ... -
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, ... -
Fusulinid and conodont biostratigraphy of the Upper Pennsylvanian–Cisuralian Riepe Spring Limestone, Spruce Mountain Ridge, Elko County, Nevada, U.S.A.
(2018-12-06)The Upper Pennsylvanian-Cisuralian (lower Permian) mixed carbonate-siliciclastic strata exposed at Spruce Mountain Ridge, Elko County, Nevada, record the shallow-marine microfauna and oscillating depositional history of ... -
Nanopetrophysical Characterization of the Wolfcamp A Shale Formation in the Permian Basin of Southeastern New Mexico, U.S.A.
(2019-12-05)The Permian Basin has been producing oil and gas for over a century, but the production has increased rapidly in recent years due to new completion methods such as hydraulic fracturing and horizontal drilling. The Wolfcamp ... -
