Abstract
A system and method for establishing hydraulic communication between relief and target wells, wherein a relief well is drilled to include a portion of the target wellbore that is axially offset from and substantially parallel to a portion of the relief wellbore. A perforating system is carried by a tubing string in a cased portion of the relief well. The perforating system includes a latch assembly, a non-rotational packer and perforating gun having charges radially oriented in a limited direction. Tubing string parameters are obtained during the run-in of the perforating system, and thereafter the tubing string parameters are utilized to engage the latch assembly with a latch coupling carried by the casing in the relief wellbore. Axial and rotational forces are applied to the tubing string to engage the latch assembly. Discharge of the perforating gun yields perforations only between the relief well and target well, establishing fluid communication.
