The Flow-Release Slick-Catch Spear provides a method of engaging and recovering tubulars or other types of equipment with a slick internal profile.
The Slick-Catch Spear can also be used where standard internal fish neck profiles have become damaged preventing the use of standard pulling tools.
The tool can be engaged into a fish simply by setting down minimal weight to overcome the spring force on the grapple. To release the tool from the fish, simply set down weight on the BHA while circulating at a pre-determined flow rate through the tool. Flow through the tools’ adjustable orifice creates the back-pressure required to move the latch grapple into the release position. The internal spring returns the grapple to the engaged position when flow through the tool is stopped. The tool can be functioned as many times as required.
The Flow-Release Slick-Catch Spear’s adjustable orifice is easily changed to adjust the activation flow rate and pressure to suit each application. Flow through the tool can also be used to wash debris from above as well as inside the fish top prior to making engagement.
