FISHING TOOLS

Fishing Spear

A Fishing Spear is used to recover from a well any equipment left there during drilling operations, such as a lost bit or drill collar or part of the drill string or to remove from an older well certain pieces of equipment (such as packers, liners, or screen liner) to allow reconditioning of the well.
It is usually the first recovery tool engaged when tools are broken off in the bore hole. The Fishing Spear screws directly on the drill rods and will endure gentle driving to aid in spearing the last tool. Fishing spears are easy to break loose if the drill tools cannot be recovered.
