Patent ID: 7556099

Claim:
A method of producing hydrocarbons from a subterranean reservoir, comprising: a. operating a first injector-producer well pair under a substantially gravity-controlled recovery process, the first injector-producer well pair forming a first mobilized zone in the subterranean reservoir; b. operating a second injector-producer well pair under a substantially gravity-controlled recovery process, the second injector-producer well pair forming a second mobilized zone in the subterranean reservoir, the first injector-producer well pair and the second injector-producer well pair together being the adjacent well pairs; c. providing an infill producer well in a bypassed region, the bypassed region formed between the adjacent well pairs when the first mobilized zone and the second mobilized zone merge to form a common mobilized zone; d. operating the infill producer well to establish fluid communication between the infill producer well and the common mobilized zone; e. operating the infill producer well and the adjacent well pairs under a substantially gravity-controlled recovery process; and f. recovering hydrocarbons from the infill producer well.
