Abstract
A process for producing gaseous hydrocarbon from a subterranean formation by hydraulically fracturing with injection of a liquid material under pressure such that a connecting fracture is generated extending between a lower injection well and an upper production well, where a gas-liquid interface is defined within the fracture or within the upper producing well, and producing gas across the gas-liquid interface.
