Technology in Action: Precision cutting of wire at depth and retrieving to surface in high deviation wellbore
During drift run operations to determine the depth of a third party retrievable bridge plug downhole, the drift assembly was unable to retract through the 5 ½” x 4 ½” completion crossover rendering it stuck downhole at a depth of 2,349m at 65 degrees deviation.
A cutter was required to free the wire (0.125” OD GD31MO) exactly at depth allowing it to be retrieved back to surface.
