  • Remote actuation testing tool for high pressure differential downhole environments
    Patent number: 8978757
    Abstract: A remote actuation tool equipped with an intermediate volumetric mechanism for enhanced tool durability in high pressure differential downhole environments. Valve segments of the tool are actuated by power available due to a pressure differential between atmospheric and hydrostatic chambers of the tool. Yet, the intermediate volumetric mechanism, whether in the form of a discrete chamber or a hydraulic line system, minimizes stresses of the differential pressure on tool hydraulics. Thus, failure rates are substantially reduced. So, for example, the tool may be reliably employed in downhole environments which present differential pressures in excess of about 30,000 PSI.
