摘要

A method of setting downhole equipment includes applying a pressure to a compensating volume 202, 204, separated from a working volume by one or more hydraulic control devices, such as check valves or restrictors. A pressure is applied to the working volume 206 in response to the pressure applied to the compensating volume. The pressure applied to the compensating volume is then reduced and the pressure applied to the working volume is captured by the hydraulic control devices 208. The captured pressure in the working volume is applied to set downhole components 210. The fluid used may be a compressible fluid such as silicone oil.
