The NOV Downhole Bowen Series 150 Releasing and Circulating Overshot is the strongest tool available to externally engage, pack-off, and pull a fish. The basic simplicity and rugged construction with which it is designed have made it the standard of all external catch fishing tools. Construction The Bowen Series 150 Releasing and Circulating Overshot is composed of three outside parts: the Top Sub, Bowl, and Guide. The Basic Overshot may be dressed with either of two sets of internal parts, depending on whether the fish to be caught is near maximum size for the particular overshot. If the fish diameter is near the maximum catch of the Overshot, a Spiral Grapple, Spiral Grapple Control, and Type “A” Packer are used. If the fish diameter is considerably below maximum catch size (usually 1⁄2”) a Basket Grapple and a Mill Control Packer are used.

  • Rugged design – Withstands pulling, torsional, and jarring strain

  • Left-hand helix grapple with tapered exterior – Conforms to the helically tapered section in the bowl

  • Sharp wickered interior – Enables stronger engagement with fish
