Shale geology
The Eagle Ford Shale is a hydrocarbon producing formation of significant importance. It is capeabe of producing both gas and more oil than other traditional shale plays. It contains a much higher carbonate shale percentage: upwards of 70% in south Texas. It becomes shallower and the shale content increases as it moves to the northwest.Shale gas reservoir has become a crucial resource for the past decade to sustain growing energy needs while reducing the carbon intensity of energy systems relative to other fossil fuels. However, these reservoirs are geologically complex in their chemical composition and dominance of nano-scale pores, resulting in limited predictability of their effective storage capacity. To predict gas ...Oil shale can be thought of as a precursor to oil and natural gas. With more pressure and over more geological time, kerogen would heat to its “oil window” or “ gas window ” (the temperature at which it would release crude oil or natural gas). A sedimentary rock, oil shale is found all over the world, including China, Israel, and Russia.

Kerogen is solid, insoluble organic matter in sedimentary rocks.

Both basalt and diabase are more resistant to erosion than the enclosing sandstone and shale, and therefore they form ridges and uplands.The pore network in organic-rich shale consists of pores associated with organic and inorganic matter. Each shale formation has a unique nature to develop a pore system (Yang et al., 2017), controlled by organic matter and mineralogy's quantity and thermal maturity. The reservoir quality depends upon pore structure, which further depends upon ...Hydraulic fracturing is a well-stimulation technique used commonly in low-permeability rocks like tight sandstone, shale, and some coal beds to increase oil and/or gas flow to a well from petroleum-bearing rock formations. A similar technique is used to create improved permeability in underground geothermal reservoirs.Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3. It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.
