TCP Gun Release Systems
Automatically drops tubing-conveyed perforating (TCP) guns at the instant of detonation to the well bottom after the guns are fired. When the guns are fired in a closed system in which the tubing pressure is less than the wellbore pressure, the CTXR gun release disconnects the TCP guns.
Allows retrieval of the running assembly if guns become stuck. The CTR is a fullbore safety release device for TCP operations. Pulling on the string with a predetermined tension and holding this tension for a predetermined time actuates the CTR.
Primarily used to anchor high-shot-density (HSD) gun strings in monobore wells. The MAXR can be run in the hole with either wireline or pipe and is set with standard setting equipment.
Automatically drops tubing-conveyed perforating guns to the well bottom after the guns are fired. A full-tubing opening exists after the gun string is dropped, and the tailpipe incorporates a muleshoe entry wireline guide. Firing heads and no-gos are dropped as one piece for easy fishing.
Enables TCP guns to be dropped off the end of the running string, allowing access to the perforated zone for stimulation, production logging, squeezing, or additional perforating. After the guns have dropped, the release housing acts as a tubing reentry guide.
Automatically drops perforating guns at the instant of detonation. The WXAR, which extends the length of the gun strings that can be conveyed into the well, can be run on for wireline, tubing, or coiled tubing. Use of the WXAR enables long intervals to be perforated at underbalanced pressure without killing the well.
