ABERDEEN, UK – Churchill Drilling Tools has delivered the first of its new HyPR HoleSaver hydraulic pipe recovery systems.
HyPR HoleSaver comprises a full-strength sub positioned in the drillstring, which can be severed in roughly one hour.
A jetting dart is launched and lands inside the sub to jet the internal API connection. After a relatively short period of pumping, the sub parts following application of a small amount of torque and/or over pull from the surface, providing a fish-neck or immediate side track cementing options.
A Churchill spokesman said: “Stuck pipe incidents cost the drilling industry millions, if not billions of dollars each year. With the sector tightening the purse strings even further, it’s paramount to ensure cost-effective solutions are established to mitigate the burden inherently associated with stuck pipe.”
The system can be run singly, normally above a circulation sub, or in multiples throughout the string to maximize coverage options, he added.
