Title: SYSTEM AND METHOD FOR PERFORATING AND TUNNELING CASED WELLS
Abstract:
A system is for forming tunnels in formation radially surrounding a wellbore. The system is characterized by: a perforating tool arrangement having a perforating tool for forming an opening within the casing and a perforating tool sensor disposed upon the perforating tool to detect at least one wellbore parameter useful to identify a location or attributes of the opening; a tunneling tool arrangement having a tunneling tool for forming a tunnel within the formation through the opening; and a controller to receive data from the perforating tool sensor indicative of the wellbore parameter and to at least partially control operation of the tunneling tool based upon the at least one wellbore parameter sensed by the perforating tool sensor.
