METHOD OF INTERCONNECTING SUBTERRANEAN BOREHOLES

摘要

A method is disclosed of connecting a first borehole (1) to a second borehole (2), said boreholes being formed in an earth formation (3) and extending at a mutual distance. The method comprises inserting a volume of hardenable fluidic material (24) into a space (22) in the earth formation extending between the first and second boreholes, and allowing the hardenable fluidic material to harden so as to form a body of hardened material between the first and second boreholes. At least one fluid channel (26) is created in said body of hardened material, each fluid channel providing fluid communication between the first borehole and the second borehole.
