What is Shale Plays in the Oil and Gas Sector?
Shale plays consist of various undiscovered, potential, discovered, or producing oil and gas reservoirs sharing specific geological properties. Shale plays, commonly known as shales. These shales consist of fine-grained sedimentary rock particles. Mineral feldspar decomposes and forms inside the shale. The shale holds several materials like organic matter, mica, pyrite, and quartz.
Shale plays are a primary source for hydrocarbons. Shale plays are commonly developed using innovations like horizontal drilling and hydraulic fracturing (fracking) to extract hydrocarbons from the tiny holes in shale rock. They contribute almost 40% of the total to the oil and gas industry in the country.
