TREX™ Toe Subs

Hydraulically Activated Tools for the First Stage of a Completion System

The Toe-XT™ Testable Hydraulic Sleeve, Toe-AP™ Hydraulic Sleeve and TREX Wet Shoe Sub lower the operational risk associated with coiled tubing runs for the first stage of cemented liner completion systems. These technologies are cost-effective and operationally flexible, helping customers save time and reduce risk when establishing communication with the reservoir post-cementing and prior to stimulation operations.

TREX Toe Subs offer many features and benefits

The Toe-XT Testable Hydraulic Sleeve allows the casing string to be pressure tested a single time before opening.

The Toe-AP Hydraulic Sleeve opens at a specific absolute pressure, saving time and cost in delivering an effective treatment of the first stage.

The TREX Wet Shoe Sub eliminates the need for a coiled tubing run to perforate the first stage in plug-and-perf operations.
