Flow Release Internal Pulling Tools
 
Flow Release Internal Pulling Tools are designed to latch and retrieve downhole tools with standard internal profiles including the disconnect portion of the Motor Head Assembly. An increase in flow rate across a jetting facility within the tool creates a pressure drop which retracts the grapple and allows it to latch into the profile on the fishi. Reduction or termination of flow results in a positive engagement with the fish for pulling or jarring operations. The flow release feature allows the tool to be cycled as many  times  as  necessary  and  is  ideally  suited  for  horizontal  applications  where  loads  to  active mechanical operated tools are difficult to achieve.
