Wellcare Hydro Trip Pressure Sub

  Hydro Trip Pressure Sub is installed in the tubing string underneath a hydraulically actuated tool such as hydraulic packer to provide a means to apply required tubing pressure to activate the tool. To set a hydrostatic packer, drop a ball to run through the tubing and packer up to the seat of Hydro-Trip Pressure Sub. And further pressure is applied to set the packer. Afterwards pressure increased to shear screws to allow the ball seat to move down until the fingers snap back into a groove. Subsequently the ball passes down the tubing through the full opening.
