Observations on the magnetic iron oxide content of particulate matter in the Sahel
(2019-05-06)Atmospheric dust influences many processes throughout the biosphere, hydrosphere, and atmosphere, most notably the climate, marine productivity, and human health. Recognizing the physicochemical characteristics of dust ... -
On The Sensitivity Of Ocean Circulation To Arctic Freshwater Pulses During The Paleocene/Eocene Thermal Maximum
(Environmental & Earth Science, 2010-03-03)The Paleocene/Eocene Thermal Maximum (PETM) corresponds to a period characterized by extreme global warming caused by a massive carbon input into the ocean and atmosphere. Approximately 55 Ma in the early Cenozoic, evidence ... -
On-road Measurement Of NOx And CO₂ Emissions From Biodiesel Produced From Different Feedstocks
(Environmental & Earth Science, 2012-07-25)Biodiesel has generated increased interest in the US and elsewhere recently as an alternative to petroleum-derived diesel. Because it can be produced from domestic feedstocks such as soybeans, canola oil, and even recycled ... -
PETROGRAPHY AND GEOCHEMISTRY OF CONTINENTAL CARBONATES IN SOUTH TEXAS: IMPLICATIONS FOR OLIGOCENE-MIOCENE PALEOCLIMATE AND PALEOENVIRONMENT NEAR SEA LEVEL
The Oligocene-Miocene Catahoula, Oakville, and Goliad formations in south Texas contain abundant continental carbonates which are useful in reconstructing paleoclimate and paleoenvironment in a near sea level region. Field ... -
Petroleum Geology Of The Leonardian Age, Harkey Mills Sandstone: A New Horizontal Target In The Permian Bone Spring Formation, Eddy And Lea Counties, Southeast New Mexico
(Geology, 2014-12)Lowstand, siliciclastic turbidite and submarine fan deposits within the Leonardian Bone Spring Formation have proved to be prolific targets for horizontal drilling across the northern portion of the Delaware Basin. Reservoir ... -
Petrophysical Characterization of the Jo Mill Submarine Fan Complex, Spraberry Trend, Midland Basin, Texas
(2017-12-01)Understanding and quantifying reservoir quality require a new suite of knowledge when approaching the nanometer sized pore-networks of unconventional reservoirs. These low porosity and permeability reservoirs have been ... -
PETROPHYSICAL PROPERTIES OF THE WOODFORD FORMATION IN THE ARDMORE BASIN IN OKLAHOMA, U.S.A
(2017-12-04)A prolific source rock in Oklahoma, the Woodford Shale has sourced petroleum reservoirs for millions of years and produced oil and gas since 1939. Not until the shale boom of the early 2000’s was the full potential of the ... -
Petrophysical Properties of the Yeso, Abo and Cisco Formations in the Permian Basin in New Mexico, U.S.A.
(2017-05-23)The area that comprises the Northwest Shelf in Lea Co., New Mexico has been heavily drilled over the past half century. The main target being shallow reservoirs within the Permian section (San Andres and Grayburg Formations). ... -
Petrophysical Studies of Well Cuttings from a Continues Geological Profile in Hockley County, Texas
(2021-12-09)The Permian Basin currently leads the oil production in the United States; however, with increasing concerns for the global climate, it is crucial for oil and gas companies to operate as economically and efficiently as ... -
Petrophysical Studies on Woodford Shale in Oklahoma and Wolfcamp Shale in Texas: A Multiple-Approach Methodology
(2022-05-09)The successful development of oil and gas from unconventional reservoirs in the United States proves the high petroleum potential that shale rock reserves. Petrophysical studies on shale rocks are an important part of ... -
Predicting Esherichia coli Levels In The Trinity River For Issuing Contact Recreation Warnings In The Dallas-Fort Worth Metroplex
(Environmental & Earth Science, 2014-03-12)E. coli is an indicator for the potential of waterborne illness. However, tests for E. coli take 18 to 24 hours to produce results. During this time, citizens may be exposed to high levels of bacteria. As contact ... -
Predicting Fracture Density In The Eagle Ford (Boquillas) Formation, Val Verde Basin, Texas
(Environmental & Earth Science, 2014-03-12)Fracture density in hydrocarbon reservoirs is an important variable for efficient production of oil and gas in tight reservoirs. Fracture density is the fracture surface area per unit of volume, and the higher the reservoir ... -
Predicting The Ancient Occurrence Of Coal Deposits Using Paleoclimate Modelling
(Geology, 2013-03-20)Coals are accumulated and consolidated remains of plant material, which means that in order to form coals, a certain amount of annual precipitation is required. This study uses paleo-precipitation data obtained from Fast ... -
Predicting The Ancient Occurrence Of Evaporites Using Paleoclimate Modelling
(Geology, 2012-04-11)Evaporites are climatic indicators that depend on two main variables: mean annual temperature and mean annual precipitation. This study constructs a model that predicts the localities of ancient evaporites based on paleo- ... -
Predicting The Geographic Distribution Of Ancient Soils With Special Reference To The Cretaceous
(Environmental & Earth Science, 2012-04-11)Different kinds of soils form in different climatic regimes. Soils closely match climatic conditions. Therefore, they are one of the best indicators of past climates. This study uses the "climate envelope" technique developed ... -
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 ... -
