Shale formation.

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]:Oil shale is a type of sedimentary rock that is rich in kerogen. Kerogen is a part of rock that breaks down and releases hydrocarbons when heated. Hydrocarbons are substances made entirely of hydrogen and carbon. Petroleum and natural gas are probably the most familiar . hydrocarbons.The hydrocarbons in oil shale can be used as an …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.
