Abstract
A pressure control system for a wet connect/disconnect hydraulic control line connector includes a reservoir and a piston in said reservoir. The reservoir contains hydraulic fluid or equivalent and the piston is biased by hydrostatic pressure or an atmospheric chamber and hydrostatic pressure. Pressure in the hydraulic line being controlled by the system is controllable based upon the existence or lack of an atmospheric chamber and its placement. The method for controlling pressure in a hydraulic control line wet connector includes running the control system and biasing the piston to control pressure.
