Indirect hydraulic fracturing method for and unconsolidated subterranean zone and a method for restricting the production of finely divided particulates from the fractured unconsolidated zone

摘要

An improved hydraulic fracturing method for fracturing an unconsolidated zone in a subterranean formation by fracturing a nearby consolidated zone to form a fracture which extends into the unconsolidated zone. This invention further relates to a method for producing fluids from an unconsolidated subterranean zone via a fracture extending from the unconsolidated zone through a consolidated zone to a wellbore.
