(Texas A&M University. Libraries, 1970)The development of high-speed computers has enlarged the scope of data processing and reduction. Many statistical methods, particularly those involving multivariate analysis, can be routinely used for the organization of ...
-
(2019-04-03)According to the 2015 Energy Information Administration (EIA) global assessment (EIA 2015), Argentina ranks third among countries in shale-gas resources and fourth in shale-oil resources. The Vaca Muerta formation in the ...
-
(Texas A&M University. Libraries, 1993)Detailed mapping of central eastern Texas using deep well log and seismic data indicate that the region is underlain by a thickened sedimentary section, referred to here as the Brazos basin. Recognition of this basin ...
-
(2013-06-04)Accumulations of dead shells in both modern coastal settings and in the rock record contain valuable information on past ecosystems and environmental conditions. However, death assemblages are not simply snapshots of living ...
-
(2018-05-04)Electromagnetic induction (EMI) methods have long been used to explore and analyze near-surface geological and hydrological components of coastal systems. However, there have been few studies that use EMI to analyze the ...
-
(2011-02-22)Granular porous material is idealized as an elastic-plastic material, where macroscopic failure occurs at a critical stress by localized dilatant shear at low effective pressure and compactional cataclastic flow at high ...
-
(2015-11-17)Surficial mangrove peat from Barnes Sound in Key Largo, Florida preserves very thick leaf mats (19-37 stacked leaves). The incoherent leaf mat occurred below the coherent leaf mat to a depth of approximately 5 cm, and ...
-
(2022-08-11)The Austin Group, comprised of chalk and marly chalk, is a classic fractured chalk play, that has seen a renaissance as an unconventional reservoir exploited by the combination of fracking and horizontal drilling across ...
-
(Texas A&M University. Libraries, 1966)The less than 2μ fraction of 96 samples from five deep-sea cores from the Sigsbee Deep and Campeche Bank, Gulf of Mexico, were analyzed by X-ray diffraction methods in order to evaluate the mineralogical content and the ...
-
(2017-05-17)Step-pool sequences have long been studied in high-gradient streams for the application in erosion control, ecology, and restoration projects. Step-pool sequences are defined as an alternating series of clasts and pools, ...
-
(Texas A&M University. Libraries, 1983)This study has examined the tectonics of convergence along the Peru Trench with the specific objective to gain insight into the sediment subduction process. Analysis of GLORIA (Geological Long Range Inclined Asdic) long-range ...
-
(Texas A&M University. Libraries, 1984)18 mesoscopic kinkbands have been studied in the Jura Mountains and the Chaines Subalpines (Switzerland and France). The kinkbands have formed in well-bedded, micritic limestones (5 to 50 cm bedding thickness) with interbedded ...
-
Depositional environment of the Sam Miguel lignite deposit in Atascosa and McMullen Counties, Texas (Texas A&M University. Libraries, 1985)Previous investigators interpreted the San Miguel lignite to be the result of swamps and/or marshes that existed on the landward side of a lagoon. The partings were "fire-splay" deposits that originated from coastal streams ...
-
(Texas A&M University. Libraries, 1975)The interpretation of the environments of deposition is an important aspect in the prediction of reservoir potential and trapping mechanisms. If trends and morphology are accurately predicted, then exploration techniques ...
-
(Texas A&M University. Libraries, 1983)Use of contaminant transport models to predict the potential for ground-water pollution at waste disposal sites has been hindered by lack of methods to determine dispersion parameters. As an aid to overcome this difficulty, ...
-
(Texas A&M University. Libraries, 1992)Two methods have been developed for evaluating formation permeability using log data. One method is an integrated simulation technique that can be used to analyze time-lapse logging measurements. The second method involves ...
-
(Texas A&M University. Libraries, 1964)Underground water represents a large portion of the available water supply, and the determination of the rate and direction of ground-water flow by the utilization of tracers provides knowledge that is useful in evaluating ...
-
(Texas A&M University. Libraries, 1981)The Oligocene/Miocene Catahoula Formation of the Texas coastal plain is a fluvial and lacustrine volcaniclastic unit composed of "normal" fluvial material mixed with distal rhyolitic air-fall ash and, in the lower coastal ...
-
(2020-01-08)This study investigates the relative influences of rock properties (porosity, clay content, grain density, and water saturation) on sediment dewatering in the interests of improving understanding of soaking enhanced oil ...
-
(Texas A&M University. Libraries, 1972)The Antlers Formation is a thick section of terrigenous sediments that forms the basal unit of a major, transgressive sequence of Early Cretaceous age in west-central Texas. The Antlers is a highly quartzose unit, consisting ...
