The Flow-Activated Releasable Fishing/ Bull Dog Spear is a variable catch, internal spear used to retrieve a lost-in-hole cylindrical fish from the well bore.
A complete range of slips are available for each tool size. To operate, simply run into the fish and set down weight, pick up and retrieve the fish. To release from the fish, set down the weight and circulate in conjunction with a Hydraulic Sequencing Tool above the spear. The spear will then release due to the flow-created differential pressure.
