Abstract
This invention relates to thermal recovery processes for recovering oil from underground formations, where steam, hot water or any other hot liquid or gas is used to heat the oil in the reservoir, thereby reducing the viscosity of the oil and allowing the oil to be recovered at economic rates. The invention is especially suited to the recovery of highly viscous oil or heavy oil, wherein significant viscosity reduction upon heating occurs, and provides for increased efficiency of recovery in conjunction with increased and controlled areal and vertical conformance. The process of the invention comprises:
(a) providing an injection/production well in fluid communication with the underground formation;
(b) establishing a desired maximum rate of injection Qi of fluid into the formation to horizontally fracture the formation;
(c) calculating for the injection rate Qi the duration of the injection to provide a desired pattern or areal extent of fracture extending from said well, and (d) injecting one or more pulses of said fluid through the well at the desired rate Qi, each for the period of time calculated in step (c) in order to fracture the formation.
