Completion procedure for pads subjected to thermal steam stimulation

Abstract From the Canadian patent

A method for the production of bitumens from a subterranean reservoir which is penetrated by a plurality of spaced apart wells. In particular, horizontal fractures are formed in the reservoir by injecting high-pressure fluid through the wells. The levels at which the fluid is injected into the reservoir are spaced apart vertically so that a horizontal fracture formed from a first well does not intersect a horizontal fracture formed from a second well. By using this method, well-to-well communication of the fluid along the horizontal fracturing is prevented and the mobilizing effects of the fluid are more uniformly distributed through the reservoir improving the efficiency of bitumens …
