ABSTRACT:
A method for forming a communication link between two boreholes including first cooling of a zone between the boreholes by pumping a cooling fluid down one borehole and producing it from the other and, after sufficient formation cooling has occurred, raising of the injection pressure at one borehole to initiate a fracture which tends to follow the cooled zone to the second borehole.
