ABSTRACT:
A process for recovering hydrocarbons from a subterranean formation having low permeability matrix blocks separated by a well-connected fracture network. Hot light gas is injected into the formation to heat the matrix blocks and create or enlarge a gas cap in the fracture network. The flowing pressure in one or more production wells is maintained at a value slightly less than the free gas pressure at the gas liquid interface, causing gas coning near the production well or wells. Both liquid and gas are recovered from below the gas/liquid interface in the fractures.
