Tubing-Conveyed Perforating

Perforate long intervals in deviated and horizontal wells

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).

Firing Systems

Reliable, versatile firing heads and systems to deliver your perforating objectives

Debris Control Tools

Circulating and isolation subs for debris prevention

Debris-Circulating Sub Accessory

Enhanced performance for heavy mud and high debris

The debris-circulating sub consists of a ceramic cone seated in a ported sub, usually positioned between the packer and the guns, typically 30 ft above the firing head.

FIS

Fluid and debris isolation sub

The fluid/debris isolation sub is an enhancement of the standard cone-type debris-circulating sub for heavy mud environments or large amounts of debris.

LSDS

Long-slot debris circulating sub

The long circulation slots enable relatively large debris to fall out into the annulus and not accumulate on the ceramic cone.

Deployment Systems

Side-mounted perforating gun system

SMS

Side Mounted Gun System

A customized system of TCP guns and special hardware that orients the short-string guns below the packer to direct all shots away from the production tubing.
