APPARATUS AND METHOD FOR HYDRAULICALLY ACTUATING A DOWNHOLE FROM A REMOTE LOCATION

摘要

An apparatus (100) for actuating a hydraulically controllable device (102) disposed in a wellbore is disclosed. The apparatus (100) comprises a downhole hydraulic fluid source (134), a hydraulic fluid passageway (136) providing a communication path between the downhole hydraulic fluid source (134) and the hydraulically controllable device (102), a valve (144) disposed within the hydraulic fluid passageway (136) and a downhole electronics package (138). The downhole electronics package (138) receives a signal from the surface to operate the valve (144) from the closed position to the open position such that hydraulic pressure from the downhole hydraulic fluid source (134) actuates the hydraulically controllable device (102).
