APPARATUS AND METHOD FOR COMPENSATION OF EXTRACTION OF NATURAL GAS FROM A NATURAL GAS FIELD

摘要

Apparatus for compensation of extraction of natural gas (g) from a natural gas field (G), in particular for preventing subsidence of strata located above the natural gas field and/or earthquakes, comprising: - one or more supply channels (1) configured to supply compensation gas to the natural gas field; and - at least a first gas source (11), couplable to the supply channels (1), which contains a non-inert gas (F). The invention further relates to a method for compensating extraction of natural gas (g) from a natural gas field (G), in particular for preventing subsidence of strata located above the natural gas field, comprising: - supplying a non-inert compensation gas to the natural gas field.
