STAVANGER, Norway – Well intervention specialist C6 Technologies says its new ComTrac system is performing field trials after extensive test well runs.
The company – a joint venture betweenArcher and IKM Group – currently has one offshore ComTrac package in the North Sea, operated by Archer, with several runs completed and further operations planned.
A ComTrac system package comprises a reel of spoolable 12-mm dia. semi-stiff carbon composite rod with internal electrical conductors, up to 10 km (6.2 mi) long; a control/spooling unit; and an injector unit and head that pushes or pulls the rod into or out of a well and provides well pressure control.
The system is said to offer various advantages over established intervention methods such as a low friction factor, high tensile strength, the power/signal communication capability with downhole strings provided by the composite rod, the ability to enter pressured wells, and the flexible constant-tension surface rig-up of the deployment system.
These features allow the system to undertake logging, perforating, electro-mechanical intervention, and standard mechanical interventions in well depths and well conditions that other current rigless conveyance methods cannot.
The surface deployment equipment features is also said to dispense with the need for line-of-sight or sheave wheel rig ups and places the maximum tension point within the injector system, claimed to enhance operational safety.
