Shale formation
A density-logging tool sends gamma rays into a formation and detects those that are scattered back. Typical logging sondes use a Cesium-137 source, which emits gamma rays of 0.66MeV. At this high energy level, Compton scattering dominates. The average electron density in the volume of formation probed by the tool controls the …Shale. Type, Sedimentary Rock.

Shale gas refers to natural gas that is trapped within shale formations. Shales are fine-grained sedimentary rocks that can be rich sources of petroleum and natural gas (see Fig. 1.4 ). Shale gas is trapped within the pores of this sedimentary rock. Gas is normally stored through three ways in gas shales [24,26]: Two factors drove the U.S. shale oil boom. First, oil prices averaged above $90 a barrel for three years, from 2011 to 2014. That was enough to allow shale exploration and production to be profitable. Second, low-interest rates gave banks and private equity investors a strong incentive to lend to shale oil companies.Chevron said Monday that the acquisition of Hess adds a major oil field in Guyana as well as shale properties in the Bakken Formation in North Dakota. Guyana …
Jan 3, 2023 · Current research on the variation in shale gas adsorption with formation depth primarily focuses on modeling using a combination of experimental data and the corresponding adsorption theory, such as the Langmuir equation, 3,5–7 supercritical Dubinin–Radushkevich (SDR) equation, 8 and Polanyi adsorption potential, 9 to develop a model for ... Bakken Shale Play, North Dakota, Montana, Saskatchewan & Manitoba (3/20/2011) PDF History animation: Bakken shale production, 1985-2010 (9/30/2011) ZIP Map dataThe Niobrara Shale is a shale rock formation located in Northeast Colorado, Northwest Kansas, Southwest Nebraska, and Southeast Wyoming. Oil as well as natural gas can be found deep below the earth's surface at depths of 3,000 - 14,000 feet. Fracking is used to extract these natural resources.Shale is a tightly packed sedimentary rock. The shale is very porous, but it is not very permeable. This allows the shale to hold a lot of oil/natural gas but makes it difficult to remove those energy sources. Recent technologies have made it possible to extract the oil and natural gas trapped in deep shale formations.

Shale formation is fine partiles that can remain suspended in water long afrer the larger particles of sand have deposited. Shales are typically deposited in very slow moving water and are often found in lakes and lagoonal deposits, in river deltas, on floodplains and offshore from beach sands.Between the shale deposit and the floor of an aquifer (which is normally found no more than a few hundred metres below the surface) are numerous layers of rock that would prevent the infiltration of gas and …
The in situ conversion process (ICP) is a retorting method pyrolyzing the kerogen in shale into oil and gas products, which shows great potential to promote the recovery of oil shale resources. In this …Shale gas is found in shale "plays," which are shale formations containing significant accumulations of natural gas and which share similar geologic and geographic properties. A decade of production has come from the Barnett Shale play in Texas. Experience and information gained from developing the Barnett Shale have improved the efficiency of ...
