• Grant Prideco™ Intervention System


    Offshore well intervention operators have recognized the effectiveness of utilizing an intervention string in comparison to the more conventional use of traditional risers for intervention work. The drill pipe intervention string provides a rugged structure, gas-tight seal, large internal diameter and corrosion-resistant exterior.

    Grant Prideco can incorporate high-performance TurboTorque-M™ (TT-M™) and eXtreme™ Torque-M™ (XT-M™) metal-to-metal seal connections into a custom design to meet customer-specific intervention requirements.

    Maximizing tool joint inside diameter and shifting tube upsets to the exterior creates an oversized inside diameter throughout the connection and tube to optimize unobstructed tool passage trough the string.

    Grant Prideco rotary-shouldered drill pipe connections are rugged and robust, and can withstand multiple make-up and break-out cycles without experiencing galling or other damage. With proper handling procedures, these connections can complete well over 100 cycles before repair or re-cut is required. Conventional pipe handling equipment for drill pipe accommodates relatively fast pick-up, make-up, running and tripping speeds. In addition, the landing string can be used for drilling if necessary.

    Drill pipe intervention risers can be provided in any of the proprietary sour service drill pipe grades of high yield strength offered by Grant Prideco for service in H2S environment
