Available in PDF, EPUB and Kindle. Book excerpt: A method for rubblizing an oil shale deposit that has been formed in alternate horizontal layers of rich and lean shale, including the steps of driving a horizontal tunnel along the lower edge of a rich shale layer of the deposit, sublevel caving by fan drilling and blasting of both rich and lean overlying shale layers at the distal end of the tunnel to rubblize the layers, removing a substantial amount of the accessible rubblized rich shale to permit the overlying rubblized lean shale to drop to tunnel floor level to form a column of lean shale, performing additional sublevel caving of rich and lean shale towards the proximate end of the tunnel, removal of a substantial amount of the additionally rubblized rich shale to allow the overlying rubblized lean shale to drop to tunnel floor level to form another column of rubblized lean shale, similarly performing additional steps of sublevel caving and removal of rich rubble to form additional columns of lean shale rubble in the rich shale rubble in the tunnel, and driving additional horizontal tunnels in the deposit and similarly rubblizing the overlying layers of rich and lean shale and forming columns of rubblized lean shale in the rich, thereby forming an in situ oil shale retort having zones of lean shale that remain permeable to hot retorting fluids in the presence of high rubble pile pressures and high retorting temperatures.

Available in PDF, EPUB and Kindle. Book excerpt: In an in situ oil shale retorting process, plastic flow of hot rubblized oil shale is minimized by injecting carbon dioxide and water into spent shale above the retorting zone. These gases react chemically with the mineral constituents of the spent shale to form a cement-like material which binds the individual shale particles together and bonds the consolidated mass to the wall of the retort. This relieves the weight burden borne by the hot shale below the retorting zone and thereby minimizes plastic flow in the hot shale. At least a portion of the required carbon dioxide and water can be supplied by recycled product gases.

Download or read book Oil Shale Technology written by Sunggyu Lee and published by CRC Press. This book was released on 1990-12-11 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the fundamental and engineering aspects of shale oil extraction, as well as the mathematical clarification of the complex transport mechanisms involved in oil shale pyrolysis. The influence of the chemical and physical environment on the enhancement of oil yield is explained, and ex situ and in situ technologies are reviewed and compared. The discussion on ex situ shale oil extraction includes both thermal and chemical extraction techniques such as retorting, solvent, and supercritical extraction. Parallels are drawn between the processes available for recovering and using other fossil fuel sources, such as coal and tar sands, and oil shale. In addition to covering the characteristics of oil shale, Oil Shale Technology summarizes the physical and chemical properties of shale oil obtained from various deposits around the world. The influence of the retorting process on the properties of the resulting oil shale is discussed, as are standardized techniques for determining these properties. Engineers, geologists, chemists, chemical engineers, and other researchers in the petroleum and chemical industries should consider this book an important reference resource.
