ABSTRACT:
Disclosed are systems for removing hydrocarbons from subterranean deposits thereof. A fluid-impervious barrier screen is formed to isolate parts of the deposit or to isolate the deposit from adjacent fluid-permeable earth formations. The barrier screens are formed by fracturing a vertical zone in the formation by micropercussive fracturing or detonation of microexplosive charges in a series of closely-spaced bore-holes to form a vertically extending fractured plane. The fractured plane is sealed with a sealing medium to form a fluid-impervious screen.
Hydrocarbons trapped in the enclosed deposit zone are flushed from the formation by recirculating a fluid medium such as superheated brine and/or hot gases through the enclosed deposit zone under sufficient pressure to cause turbulent flow through the pore formations and to relieve the overburden pressure. The flushing medium may be injected in a series of pressure pulses to force the fluid through the pores by hydraulic ramming.
In situ gassification is also performed in subterranean deposits isolated by the barrier screens to form gas products for exploiting liquid reserves and to remove immobile reserves as a gas product.
