The Evolution Model E Hydro-Trip Sub is used to hydraulically set tools, such as hydraulic packers with the application of tubing pressure. Setting is achieved by circulating a ball to a seat in the sub, and applying sufficient pressure to activate the setting mechanism in the tool below.

When further pressure is applied to the ball, the mechanism shears, allowing the ball to pass down the tubing string.

After the Hydro-Trip Sub has been set, the tool provides an open bore for passage of drop balls or wireline equipment.

Operation

To set a hydraulic packer, drop or circulate a ball down the tubing to the seat in the Hydro-Trip Sub.  Apply sufficient tubing pressure to activate the setting mechanism in the packer.

After the packer is set, a pressure increase shears the shear screws in the shear ring, to allow the ball seat to move down until the fingers snap back into a groove.  The sub is then fully open with no restrictions to productions, and the ball passes on down the tubing.
