Flow activated releasable spear

Description:

Flow activated releasable spear is a variable internal spear used to retrieve a lost cylindrical fish from the wellbore. 

A complete range of slips is available for each size tool. To operate, simply run into the fish, set down and then pick up the weight, and retrieve the fish. 

To release from the fish, simply set down the weight and circulation in conjunction with a hydraulic sequencing tool above the spear. The spear will then release due to the flow differential created. 

A complete range of hardened slips are available for each size tool.
