Page last modified

April 11 2024

TRIDENT - a modular rotary driven, single-trip cut and pull system that incorporates several innovative trip saving features including an integral tension set packer and a hydraulically activated spear in conjunction with the ability to either run & set a bridge plug or dress a cement plug prior to commencing the cutting and recovery of the target casing.

TRIDENT has inbuilt extras including: cut verification capability; a swarf management system to avoid swarf entering sensitive well control equipment; a spear which sets in both 9-5/8” and 10-3/4” sizes for tapered casing; annulus circulation around the cut casing, and other features.

The next generation, the Shogun System, is built on the same qualities of TRIDENT but also includes cement thru capabilities. Enabling single trip operations to set a Bridge Plug, place Cement Plug & test, cut casing and recover to surface.
