Dislodge wellbore obstructions, remove debris, and retrieve tubular fish from the wellbore

Debris catcher

The Schlumberger Debris Catcher is a modular system, which uses reverse circulation to remove debris from the wellbore. Pumping through the tool provides energy to lift debris/fish from the bottom of the hole, object, or obstruction point. The lower end of the tool can be configured in one of three ways depending on the application: vacuum for small debris, fishing for large debris, and washover shoe for packer, plug and milling operations.

Junk magnet

Small, oddly shaped debris with magnetic properties can adversely affect tool performance. Junk magnets are run in advance of diamond tools to remove this debris. They are constructed so that the internal pole plate is highly magnetized, but the rest of the tool remains nonmagnetic. Junk magnets are available in most hole sizes.

Impression block

Used to determine the position and condition of the top of a fish or junk in a well, impression blocks feature a steel body and a lower end fitted with a block of soft material, typically lead. The tool is made up on the running string and lowered without rotation to make contact with the obstruction, leaving an impression that can be identified at surface. From this information, the appropriate fishing equipment can be deployed.

Casing scrapers

Casing scrapers are used to remove paraffin, hardened mud, cement, or burrs resulting from tool runs or perforations from the inner surfaces of a tubular. They are particularly useful for cleaning up the casing before setting a packer. A broad range of casing scraper types and sizes are available for a variety of applications. Casing scrapers feature a pressure-compensated construction to resist hydrostatic and circulation pressure effects and can be operated with conventional or reverse circulation.

Pin tap

Along with taper taps, pin taps provide an economical means to retrieve a tubular fish that is restrained from rotation. They are designed to mate with a box-up tool joint and include an open bore to allow wireline tools to be run through the tap.

Box tap/die collar

Box taps are designed to externally engage and retrieve a tubular fish that is rotationally locked. Available with a choice of special guides, box taps are well-suited for threading onto ragged-surface fish.

Taper tap

Along with pin taps, taper taps provide an economical means to retrieve a tubular fish that is restrained from rotation. One-piece taper taps are constructed with a fine thread form that allows the tap to work as a threading tool.
