Learn about shale rock, including what type of rock is shale and the shale formation process. Discover the characteristics of shale and where to find shale. Updated: 11/21/2023 Table of Contents What is Shale Rock? What Type of Rock is Shale? How is Shale Formed? Shale Depositional ...
These "other constituents" in the rock are often determined by the shale's environment of deposition, and they often determine the color of the rock.Black shale: Organic-rich black shale. Natural gas and oil are sometimes trapped in the tiny pore spaces of this type of shale. Colors of ...
The meaning of SHALE is a fissile rock that is formed by the consolidation of clay, mud, or silt, has a finely stratified or laminated structure, and is composed of minerals essentially unaltered since deposition.
sandy shale can be divided into silty shale and sandy shale. Organic-rich shale is the major rock type for the formation of shale gas, which includes black shale and carbonaceous shale. Black shale includes large amounts of organic matter, fine and scattered pyrite, andsiderite, where TOC is...
Pore structure, a critical factor influencing the physical properties of oil and gas reservoirs, shows great variation with the reservoir rock type. Efficient exploration and development of oil and gas resources require comprehensive understanding of pore structure differences between various reservoirs. In...
Oil shale is a sedimentary rock containing the hydrocarbon “kerogen,” a high molecular mass organic material that is insoluble in all common organic solvents and is not a member of the petroleum family. Oil shale deposits occur throughout the world and may, in fact, represent the most abunda...
In the numerical model, the load plates are applied on the top and the bottom of the rock specimen with infinite stiffness. The vertical displacement of the load plate is related to the loading time. To simulate the quasi-static loading process, it is necessary to keep the load plate ...
“A” is in the range of 0.012%–0.251%, and the hydrocarbon-generating potential is 0.42–2.86 kg/t. The type of kerogen is mainly Type III and partly Type II2, and is thus a hydrocarbon-source rock suitable for the production of mainly gas. The dark mudstones of the Carboniferous-...
Using the ‘Elab-TOC’, Rock-Eval analysis was conducted on the powders drilled from different lamina to analyze the TOC. For kerogen extraction and carbon-isotope analysis, a microdrilling sample of approximately 1.0 g was extracted from each selected area, and 6–12 mg of kerogen was ...
Shale oil is alsodifferent from "oil shale", which is a type of sedimentary rock that has low permeability and bituminous-like (consisting mainly of hydrocarbons) solids that can be liquefied during the extraction process. That is, oil shale is the sedimentary rock formation containing a type o...
