Definition - What does Gas Reservoir mean?
Gas Reservoir is a naturally occurring storage area of natural gas which is contained in fracture or porous rock formations. The reservoir rocks are permeable and are made up of sandstones, limestones, and dolomites. There are two main types of Gas Reservoirs, i.e., lithologic structural gas reservoir and lithologic gas reservoir. The primary purpose of the reservoir is to explore the natural gas formed in the porous rock formations. Thus, it is used in the hydrocarbon exploration methods.
Petropedia explains Gas Reservoir
The discovery of Gas Reservoirs has affected the expansion of gas drastically. These reservoirs are found near the accumulations of crude oil in the earth’s crust. Gas Reservoirs with low permeability and which produces dry natural gas are said to be tight gas reservoirs. The engine bleed air is often used as a pressure regulator on the Gas Reservoirs. Moreover, for the natural gas reservoirs, there should be sufficient amount of gas so that it can provide an uninterrupted flow of liquid to the pump. Baffles are used in the reservoir to halt foaming and vortexes.
