Operators have no viable option but to use standard cutters and spears for casing recovery, wasting valuable rig time on multiple trips. This old, single-purpose equipment is not optimised for the subsea environment, offering only limited functionality and relying on the availability and competence of field service. Pressure to save money and deliver solutions for late life and end life projects has never been greater, but there has not been an easy answer.
TRIDENT - a 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 can tag cement or set a bridge plug, cut, and recover casing to surface in a single trip. The system allows the elimination of multiple trips in and out of hole, saving significant rig time in single-cut operations, and even more where multiple cuts are required.
TRIDENT was designed for simplicity of operation, with the aspiration of enabling other service contractors or the rig crew to perform simple casing recovery operations, reducing POB once fully trained. The TRIDENT system is made up of three modules - the TRIDENT cutter, the TRIDENT anchor, and the TRIDENT tension set packer.
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.
