IDEAL GEOLOGICAL CONDITIONS FOR STORING NATURAL GAS IN POROUS FORMATIONS

Before being stored, the natural gas is compressed and then injected into the deep-lying porous rock, from where it can be extracted when needed. The reservoir rock’s high permeability and 100 metre thickness make it possible to extract about 1.1 million m3 of natural gas per hour from the storage facility.
