STH-2 Setting Tool

STAR HPT HYD SETTING TOOL is used to hydraulically set a mechanical packer and permit circulation of the well bore before setting the packer. This HPT design incorporates a Hydraulic and Right Hand rotational to release from the packer after set. Once the setting tool with packer located at the predetermined position, the tripping ball is dropped down to the tubing string and allows it to seat on the Inner Sleeve. Pressure is then applied to the tubing to shear the inner piston downward and open the communication port in the HPT for set the packer, continuously apply the pressure will sheared HPT top shear inner sleeve pins, allow the shear sleeve assembly it to move downward, expand and no-go in the mandrel. The expanded top ball seat assembly permitted the ball passes through and lands on the lower ball seat assembly, apply pressure for set packer and release Hydraulic Setting Tool from packer.

The HPT is attached to the top sub of the packer by the left hand thread by rotational. The set of lugs latches into the setting sleeve of the packer. Once the packer has reached the desired depth, the tripping ball is dropped to land on the top ball seat assembly. Pressure is then applied to the running string, sheared the shear pin in the stopper to allow the top ball seat assembly sheared and moved downward open the communication port in the HPT tool, continuously apply the pressure will sheared HPT top shear inner sleeve pins, allow the shear sleeve assembly it to move downward, expand and no-go in the mandrel. The expanded top ball seat assembly permitted the ball passes through and lands on the lower ball seat assembly. apply pressure stroked the piston downward and pushes the packer setting sleeve and all of the external components of the packer downward and set the packer in predetermined position. Once the packer is set,   increased the pressure to shear release the HPT form packer, continuously apply the pressure will shear the bottom ball seat screws, this shear will drop the ball & ball seat into the bottom cap to equalize the pressure top and bottom.
