摘要： A technique facilitates use of sensor data, e.g. pressure data, associated with hydraulic control lines. According to an embodiment, a well string is deployed in a borehole and comprises a tool coupled with a hydraulic control line and operated via hydraulic inputs delivered through the hydraulic control line. Additionally, a sensor is coupled to the hydraulic control line to monitor pressure in the hydraulic control line. The sensor may be located permanently downhole proximate the tool. A control module is configured to collect data from the sensor and to compare the data to a baseline pressure profile associated with the tool. The sensor data may be used to determine characteristics related to operation of the tool.

摘要： A downhole tool in accordance to aspects of the disclosure includes a housing forming a bore to convey a wellbore fluid, an actuating piston moveably disposed in a cylinder located in the housing adjacent to the bore and a barrier fluid isolating the actuating piston from the bore. The downhole tool may include a compensator piston in communication with the barrier fluid and the bore that is moveable to balance the pressure between the barrier fluid and the bore.
