The HyPR HoleSaver consists of a full-strength sub positioned in the drillstring, which is severed in about one hour. A jetting dart is launched and lands inside the sub and, after a relatively short period of pumping, the sub parts easily under a small loading, offering a perfect fish-neck or immediate sidetrack cementing options.
The HyPR HoleSaver can be run singly, normally above a circulation sub, or in multiples throughout the string to maximise coverage options.
