Continuous Cutting Overshot - Thru-Tubing Technologies
The Continuous Cutting Overshot is used to cut and retrieve continuous tubing that
have been parted, stuck, and/or abandoned in the wellbore. The tool consists of
a Top Sub, Bowl, Guide, Shearable Slip Bowl, Grapple and Cutting Grapples Operation.
The Continuous Cutting Overshot is attached on the fishing string, lowered to the
top of the fish and then stripped over to the desired depth. To initiate the cut,
simply pick up on the work string, to set the grapple and shear the shear screws.
This will force the cutting grapples into the fish, shearing it in two and leaving
a clean top for further retrieval or entry for wireline equipment. The overpull
to cut the coil is only 25-30% of the yield of the tubing being cut (this can vary
due to well bore friction, spalling of cutting grapple blades, etc.). The overshot
is not a releasable tool for upward travel, but it can be released to travel down
hole (providing the shear screws have not been sheared). Simply bump down sharply
to release the grapple and continue to the desired depth.
