Tubing-conveyed perforating (TCP) completion techniques enable perforating very long intervals in one run—some TCP strings have exceeded 8,000 ft [2,440 m] in length—and in highly deviated and horizontal wells, TCP is the only means of accessing the perforating depth. TCP also facilitates running large guns and using high underbalance. When TCP is deployed in conjunction with drillstem test (DST) tools, well fluids can be easily controlled. Without having to kill the well, TCP strings can be retrieved (shoot and pull) or left as part of the permanent completion (integrated TCP).
Reliable, versatile firing heads and systems to deliver your perforating objectives
Circulating and isolation subs for debris prevention
Enhance performance for heavy mud and high debris.
Operate in environments with heavy mud or with large amounts of debris.
Enable relatively large debris to fall out into the annulus and not accumulate on the ceramic cone.
Side-mounted perforating gun system
Orient the short-string guns below the packer to direct all shots away from the production tubing.
Reliable automatic, hydraulic, and mechanical actuation options
Underbalance and pressure management for TCP
Active shock absorption that prevents damage
