What is a shale
What is shale gas and how much is there globally? Shale gas is a form of natural gas (mostly methane), found underground in shale rock. It is classified as ‘unconventional’ because it is found in shale , a less permeable rock formation than sandstone, siltstone or limestone in which ‘conventional’ gas is found, and it is generally distributed over a much larger area.Shale is a common sedimentary rock found in all parts of the world formed by the consolidation of a mixture of mud and silicates over millions of years.

Shale oil is an unconventional oil produced from oil shale rock fragments by pyrolysis, hydrogenation, or thermal dissolution. These processes convert the organic matter within the rock ( kerogen) into synthetic oil and gas.Shale oil is originated from the retention and accumulation of generated hydrocarbons in the source rocks. It is the residual oil which has not been expelled after hydrocarbon generation. Shale oil experiences no migration or only primary migration, which is a typical self-generating and self-reservoiring system.Oil Shale is a rock that contains significant amounts of organic material in the form of kerogen. Up to 1/3 of the rock can be solid organic material. Liquid and gaseous hydrocarbons can be extracted from the oil shale, but the rock must be heated and/or treated with solvents.Shale is a sedimentary rock while slate is a metamorphic rock formed from shale.

When encountering shale during drilling operations, water in the drilling fluid may interact with the clay materials within the formation, causing the shale to swell. This can lead to instability in the wellbore, and dispersion of shale into the drilling fluid (sloughing), eventually leading to hole washout. Depending on ...Shale, any of a group of fine-grained, laminated sedimentary rocks consisting of silt- and clay-sized particles. Shale is the most abundant of the sedimentary rocks, accounting for roughly 70 percent of this rock type in the crust of the Earth. Shales are often found with layers of sandstone orOil shale is an organic-rich fine-grained sedimentary rock containing kerogen (a solid mixture of organic chemical compounds) from which liquid hydrocarbons can be produced. In addition to kerogen, general composition of oil shales constitutes inorganic substance and bitumens. Based on their deposition environment, oil shales are classified as ...

Shale forms in depositional environments full of biomatter and therefore is a source of fossil fuels. Shale is hydraulically and horizontally drilled and fracked for its oil and natural gas. Shale ...The shale rock piece (10 g) was evacuated under the required conditions. The non-wetting fluid such as mercury act as the active probe to access the pore by following these parameters: the contact angle of 130°; Hg density of 13.53 g/mL; mercury surface tension as 485 dyn/cm. Hg filling pressure as 0.51 psi was applied, followed by injecting ...Oil shale is a dirty and expensive source of unconventional oil. Oil shale is a mixture of sand, silt, salt, and an insoluble organic substance called kerogen. Rock-like at room temperature, oil shale produces vapors and gases when heated, which in turn are condensed and turned into oil. Oil shale shouldn't be confused with "shale oil," also ...…
