How is natural gas produced

“Blind” extraction
Natural gas occurs in fine pores of some rocks. Depth, at which natural gas is located, varies from 1,000 meters to several kilometers. The process of gas production meaning its extraction from the subsurface, collection and treatment for transportation starts upon the completion of geological exploration after the deposits have been identified.

Well drilling
Gas is extracted from the subsurface using specially drilled wells called producing or operating wells. In fact, there are many types of wells, and they are used not only for extraction, but also for studying the geological structure of the subsurface, prospecting for new fields, supporting operations, etc.

Borehole is cased and cemented.
