PARALLEL HORIZONTAL WELLS

摘要

PARALLEL HORIZONTAL WELLS The disclosed invention is a method of recovering hydrocarbons through parallel horizontal wells by use of steam and water injection. Steam is injected into two parallel horizontal wells to stimulate the formation and then the second horizontal well is converted to a production well. About the time of steam breakthrough at the second well, the steam injection at the first well is converted to water injection, production is suspended from the second well, and steam is injected through the second and third wells. After a suitable period of stimulation time, the third well is converted to a producing well, steam injection is continued through the second well, and water injection is continued through the first well.
