The physical properties 14 Dec 2011 (7) Geophysical properties, when calibrated to rock properties, provide a Risks and uncertainties associated with gas- and oil-rich shales 24 Jun 2014 Oil shale is sedimentary rock containing up to 20 % kerogen, a solid bituminous as it is these that determine the energy properties of the rock.

Oil shales require a specialized log analysis property of the rock, it does not provide information on Oil Shale and Tar SandsThe United States holds more than half the world's oil shale, a fine-grained sedimentary rock containing organic matter from and abundant, U.S. tar sands have different properties and would require different – and as Extracting oil from U.S. public lands through oil shale or tar sands would deal a contains kerogen, which is released as a petroleum-like liquid when the rock is
Mechanical properties of the shale rock fabric, which include mainly: elasticity coefficients, compressive strength, extensional strength; primarily dependent on the mineral composition which follows the distribution of facies within the sedimentary basin. The content of clay substance is a key decisive factor behind shale properties. Shale oil is a high-quality crude oil that lies between layers of shale rock, impermeable mudstone, or siltstone. Oil companies produce shale oil by fracturing the layers of rock that contain the layers of oil. Don't confuse shale oil with oil shale. That is rock suffused with kerogen, a precursor to oil. Ductile shale naturally heals, while brittle silty shale with a quartz fraction is more likely to fracture and remain open.11 Geomechanical properties aid in determining relative brittleness or ductility of rock, providing valuable input into completion and fracture stimulation design. A combination of static and dynamic testing— Oil shale is essentially rock that contains solid bits of kerogen, a precursor to oil. All oil is from organic matter that is subjected to intense heat and pressure until it breaks down into hydrocarbons. With the kerogen in oil shale, there wasn’t quite enough heat to finish the job–but that, of course, can be fixed.
Oil shale is the rock from which shale oil is extract ed. Shale oil is similar to petroleum, and can be refined into many different substances, including diesel fuel, gasoline, and liquid petroleum gas ( LPG ). Companies can also refine shale oil to produce other commercial products, such as ammonia and sulfur. Oil Shale is organic-rich sedimentary rocks that have contain kerogen (insoluble organic matter in sedimentary rock. When subjected to intense heat, these shales yield oil. Oil shales range from brown to black in color. They are flammable and burn with a sooty flame. Oil shale, any sedimentary rock containing various amounts of solid organic material that yields petroleum products, along with a variety of solid by-products, when subjected to pyrolysis—a treatment that consists of heating the rock to above 300 °C (about 575 °F) in the absence of oxygen. The
