Tubing-Conveyed Perforating

Perforate long intervals in deviated and horizontal wells

perforating charges

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).
