Available in PDF, EPUB and Kindle. Book excerpt: Permeability may be altered in the Earth by plastic flow of the rock matrix. To better understand the relation between plastic flow and pore geometry, we measured the permeability of a suite of hot-pressed calcite samples with differing porosities. We found the permeability dramatically decreased with decreasing porosity, particularly in the range of 10 to 4% total porosity. These results agree with a model for pore geometry changes during hot-pressing as previously developed for ceramics. Measurements of unconnected and interconnected porosity showed that the interconnected porosity virtually disappeared in samples with a total porosity of 4% or less. SEM observations showed that porosities of samples above 10% total porosity were composed of large 'spheroidal' pores, often connected by 'tubular' pores. During the last stage of hot-pressing, these 'tubes' are thought to collapse, making the pore network disconnected. A new approach has been developed by which changes in rock stress can be measured directly. The measurement of stress change depends on the reaction of a slender, compliant cavity to the transient variations of rock stress about the cavity. A liquid-filled pressurized cell, emplaced in the cavity, provides the means by which changes in pressure can be monitored. Earthquake-related variations in the stress field in a highly fractured quartz-monzonite stock have been observed to occur in a characteristic way prior to a microseismic event. The precursory stress change (decompression followed by compression) lasted about five hours and led directly a stress drop of 15 millibars. (EDC).

Available in PDF, EPUB and Kindle. Book excerpt: Mechanics, the oldest branch of physics, to this day remains the basis for modern technology. This is especially evident with regard to the oil and gas industry. Almost all of the technological processes in these branches of industry, from the drilling of wells to the transporting of oil and gas products via pipelines, are mechanical in their nature. The processes of the development of oil and gas deposits are of primary importance in the whole technological chain of oil and gas extraction from the rocks and their transportation to the customer. The use of scientific methods for improving technology is a long-established tradition of oil and gas industry. For the Western reader, it is enough to mention the fundamental treatises by the outstanding American research scientist and engineer M. Muskat (1937, 1949) as well as the excellent books of Scheidegger (1960) and Collins (1961) which combine practical goals with profound theoretical analysis. The initiators of the application of mechanics for solving problems of the oil and gas industry in the U.S.S.R. were V.G. Shukhov (1981) and LS. Leibenzon (1934, 1947, 1953, 1955) whose works constitute admirable examples of Soviet technical thought. During recent times, the magnitude of oil and gas extraction has increased immensely and many reservoirs with complicated physical and geological properties have, therefore, entered into the development. The fundamental problem of enhancing oil and gas recovery from rocks has been intensively and deeply analyzed.

This book was released on 2023-04-13 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physics of Fluid Flow and Transport in Unconventional Reservoir Rocks Understanding and predicting fluid flow in hydrocarbon shale and other non-conventional reservoir rocks Oil and natural gas reservoirs found in shale and other tight and ultra-tight porous rocks have become increasingly important sources of energy in both North America and East Asia. As a result, extensive research in recent decades has focused on the mechanisms of fluid transfer within these reservoirs, which have complex pore networks at multiple scales. Continued research into these important energy sources requires detailed knowledge of the emerging theoretical and computational developments in this field. Following a multidisciplinary approach that combines engineering, geosciences and rock physics, Physics of Fluid Flow and Transport in Unconventional Reservoir Rocks provides both academic and industrial readers with a thorough grounding in this cutting-edge area of rock geology, combining an explanation of the underlying theories and models with practical applications in the field. Readers will also find: An introduction to the digital modeling of rocks Detailed treatment of digital rock physics, including decline curve analysis and non-Darcy flow Solutions for difficult-to-acquire measurements of key petrophysical characteristics such as shale wettability, effective permeability, stress sensitivity, and sweet spots Physics of Fluid Flow and Transport in Unconventional Reservoir Rocks is a fundamental resource for academic and industrial researchers in hydrocarbon exploration, fluid flow, and rock physics, as well as professionals in related fields.

Download or read book Experimental and Theoretical Studies of Reactive Transport Processes in Soluble Porous Rocks written by Wei Li (Ph.D.) and published by . This book was released on 2019 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: Underground reactive transport processes involve fluid flow and reactions (dissolution, precipitation, and pressure solution) driving the evolution of the rock-fluid systems, which may result in favorable processes such as increased oil production by reservoir acid stimulation, or undesired processes such as caves and subsidence. Flow and reaction in the rock matrix often induce wormholes, which are long, finger-like channels that form due to the dissolution heterogeneity in the matrix. These wormholes become major flow pathways, which greatly increase the permeability of the rock. To study the reactive transport processes and the formation of wormholes, experimental and theoretical studies were conducted. More specifically, a new experimental setup and data analysis methods were introduced to the tube flow tests and core flood tests to experimentally study the evolution of the rock-fluid system. Theoretical studies with analytical and numerical models were used to simulate the experimental results and provide theoretical explanation for the experimental observations. Through the experimental and theoretical studies, this research improved the fundamental understanding of reactive transport processes in rock-fluid systems. This in turn provided accurate prediction of the evolution of the rock-fluid systems driven by the reactive transport processes.

Available in PDF, EPUB and Kindle. Book excerpt: Scientific understanding of fluid flow in rock fracturesâ€"a process underlying contemporary earth science problems from the search for petroleum to the controversy over nuclear waste storageâ€"has grown significantly in the past 20 years. This volume presents a comprehensive report on the state of the field, with an interdisciplinary viewpoint, case studies of fracture sites, illustrations, conclusions, and research recommendations. The book addresses these questions: How can fractures that are significant hydraulic conductors be identified, located, and characterized? How do flow and transport occur in fracture systems? How can changes in fracture systems be predicted and controlled? Among other topics, the committee provides a geomechanical understanding of fracture formation, reviews methods for detecting subsurface fractures, and looks at the use of hydraulic and tracer tests to investigate fluid flow. The volume examines the state of conceptual and mathematical modeling, and it provides a useful framework for understanding the complexity of fracture changes that occur during fluid pumping and other engineering practices. With a practical and multidisciplinary outlook, this volume will be welcomed by geologists, petroleum geologists, geoengineers, geophysicists, hydrologists, researchers, educators and students in these fields, and public officials involved in geological projects.
