Book Description
Ordovician age hydrocarbons have been drilled in the Permian Basin of West Texas since the early 1940s and have produced over a billion barrels of oil with additional natural gas. The source rock for these previously drilled Ellenburger Group reservoirs has been suggested to be the Simpson Group shales, but limited total organic carbon studies and no x-ray fluorescence analysis has been performed on the Permian Basin Ordovician rocks to determine the overall lithology and trace element enrichment relative to total organic carbon to substantiate this statement. The majority of Ordovician hydrocarbon production has occurred in faulted and structural traps in the Ellenburger, but the hydrocarbons have a different hypothesized source due to generally low total organic carbon within this group. Trace element enrichments can serve as indicators of the presence of organic material and paleoredox conditions. This study utilizes x-ray fluorescence elemental data and total organic carbon data from Permian Basin Ordovician sediments to analyze general rock lithology and to understand whether biologically- and paleoredox-sensitive trace elements coincide with total organic carbon, and if so, can these similarities give insight to the organic enrichment of these sediments and the paleoredox conditions present during their deposition. The findings of this study suggest that the Simpson Group reflects a depositional environment with intermittent layers of sandstone, green shale, black shale, red shale, and a large percentage of carbonate suggesting a shallow water marine environment. The majority of trace elements that serve as useful proxies for total organic carbon within these sediments are mostly associated with the detrital shale influx and are not associated with biological activity or paleoredox conditions. The majority of the total organic carbon values for the Simpson Group and Ellenburger Group suggest a poor (

Book Description
Investigations about porosity in petroleum reservoir rocks are discussed by Schmoker and Gautier. Pollastro discusses the uses of clay minerals as exploration tools that help to elucidate basin, source-rock, and reservoir history. The status of fission-track analysis, which is useful for determining the thermal and depositional history of deeply buried sedimentary rocks, is outlined by Naeser. The various ways workers have attempted to determine accurate ancient and present-day subsurface temperatures are summarized with numerous references by Barker. Clayton covers three topics: (1) the role of kinetic modeling in petroleum exploration, (2) biological markers as an indicator of depositional environment of source rocks and composition of crude oils, and (3) geochemistry of sulfur in source rocks and petroleum. Anders and Hite evaluate the current status of evaporite deposits as a source for crude oil.

Book Description
Reservoir Characterization is a collection of papers presented at the Reservoir Characterization Technical Conference, held at the Westin Hotel-Galleria in Dallas on April 29-May 1, 1985. Conference held April 29-May 1, 1985, at the Westin Hotel—Galleria in Dallas. The conference was sponsored by the National Institute for Petroleum and Energy Research, Bartlesville, Oklahoma. Reservoir characterization is a process for quantitatively assigning reservoir properties, recognizing geologic information and uncertainties in spatial variability. This book contains 19 chapters, and begins with the geological characterization of sandstone reservoir, followed by the geological prediction of shale distribution within the Prudhoe Bay field. The subsequent chapters are devoted to determination of reservoir properties, such as porosity, mineral occurrence, and permeability variation estimation. The discussion then shifts to the utility of a Bayesian-type formalism to delineate qualitative ""soft"" information and expert interpretation of reservoir description data. This topic is followed by papers concerning reservoir simulation, parameter assignment, and method of calculation of wetting phase relative permeability. This text also deals with the role of discontinuous vertical flow barriers in reservoir engineering. The last chapters focus on the effect of reservoir heterogeneity on oil reservoir. Petroleum engineers, scientists, and researchers will find this book of great value.

Book Description
With the passage of the Asbestos Hazard Emergency Response Act, AHERA, Public Law 99-519, it was clear that great quantities of asbestos would be disturbed and would require proper management and disposal. If these were poorly done, many people would be placed at risk unnecessarily.Into such an environment, a book dealing with the many diverse facets of asbestos abatement, written by people with substantial experience, seemed reasonable and appropriate, but even more so, necessary.

Book Description
We are poised to embark on a new era of discovery in the study of geomorphology. The discipline has a long and illustrious history, but in recent years an entirely new way of studying landscapes and seascapes has been developed. It involves the use of 3D seismic data. Just as CAT scans allow medical staff to view our anatomy in 3D, seismic data now allows Earth scientists to do what the early geomorphologists could only dream of - view tens and hundreds of square kilometres of the Earth's subsurface in 3D and therefore see for the first time how landscapes have evolved through time. This volume demonstrates how Earth scientists are starting to use this relatively new tool to study the dynamic evolution of a range of sedimentary environments.

Book Description
Permeability is the primary control on fluid flow in the Earth’s crust and is key to a surprisingly wide range of geological processes, because it controls the advection of heat and solutes and the generation of anomalous pore pressures. The practical importance of permeability – and the potential for large, dynamic changes in permeability – is highlighted by ongoing issues associated with hydraulic fracturing for hydrocarbon production (“fracking”), enhanced geothermal systems, and geologic carbon sequestration. Although there are thousands of research papers on crustal permeability, this is the first book-length treatment. This book bridges the historical dichotomy between the hydrogeologic perspective of permeability as a static material property and the perspective of other Earth scientists who have long recognized permeability as a dynamic parameter that changes in response to tectonism, fluid production, and geochemical reactions.
