Abstract

A system for establishing hydraulic communication between a relief well and a target well, 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. Thereafter, a milling system is disposed in the relief well and utilized to mill a casing window that is facing the target well. The portion of the relief well is positioned so that fluid introduced into the relief well will flow through the formation to the target well. To enhance the flow, the formation and/or the casing of the target well may be perforated, milled or partially drilled. A latch coupling disposed in the relief well casing may be utilized to engage a latch on of the milling and or a perforating tool in order to ensure proper orientation relative to the target well.
