The CE CT Releasable Spear is a hydraulic release action tool used for fishing downhole tools, with internal necks or cylindrical parts of broken tools without a fish neck that have been lost in the well.
The CE CT Releasable Spear has hardened grapple slips arranged over a tapered mandrel. Once the grapple slips are engaged in the fish, upward jarring will make the teeth bite and hold fast.
The tool release is achieved by increasing the CT flow/pressure to operate a piston which disengages the tapered mandrel from the grapple slips.
The CE Releasable Spear is available in sizes covering a wide range of fishing diameter requirements.
