ABERDEEN, UK– CNR International has contracted Deep Casing Tools to supply well construction equipment for the Espoir development offshore Cote d’Ivoire.
The award follows successful deployments for CNR in the North Sea.
Deep Casing Tools will supply itsTurbocaser Express technology for high-speed reaming to land casing at target depth, reducing operational risk, and saving time.
Landing casing in highly deviated wells and unstable formations can be challenging, the company says, and can lead to potential budget overruns and production delays. The tools provide reamer shoe rotation without casing rotation, with a unique internal assembly that offers rapid drill-through.
It will also deploy its Turborunner technology for high speed rotational reaming to land completions or liners. The system operates with low pressure and protects the completion from vibration, reactive mechanical torque, and uncontrolled pressure spikes.
Effectively, the technology combines a wiper trip with the running of the completion, without any string rotation.
