SYSTEMS AND METHODS FOR PRODUCING VISCOUS HYDROCARBONS FROM A SUBTERRANEAN FORMATION THAT INCLUDES OVERLYING INCLINED HETEROLITHIC STRATA

摘要

Systems and methods for producing viscous hydrocarbons from a subterraneanformationthat includes overlying inclined heterolithic strata are disclosed herein. Thesystems include thesubterranean formation, which includes a lower zone and an overlying inclinedheterolithic strata(IHS) zone. The systems also include a heated chamber within the lower zone,an IHS injectionwell extending within the IHS zone, and a mobilizing fluid supply system. TheIHS injectionwell includes an IHS injection well conduit that is in direct fluidcommunication with the IHSzone, and the mobilizing fluid supply system is configured to provide amobilizing fluid streamto the IHS injection well. The IHS injection well is configured to inject themobilizing fluidstream into the IHS zone to facilitate flow of viscous hydrocarbons from theIHS zone. Themethods include methods of utilizing the systems.
