摘要： 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.
摘要翻译：配有中间体积机构的远程致动工具，用于在高压差压井下环境中提高刀具耐用性。由于工具的大气压力和静液压室之间的压差，工具的阀段由可用功率驱动。然而，中间体积机构，无论是以离散腔室或液压管路系统的形式，都能最大限度地减少工具液压系统上的压力差。因此，故障率显着降低。因此，例如，该工具可以可靠地用于存在超过约30,000PSI的压差的井下环境中。

摘要： A tool that is usable with a well includes a valve element, a mechanical operator, a pressure chamber and a regulator. The valve element has a first state and a second state. The mechanical operator responds to a predetermined signature in an annulus pressure relative to a baseline level of the annulus pressure to transition the valve element from the first state to the second state. The pressure chamber exerts a chamber pressure to bias the mechanical operator to transition from the second state to the first state. The baseline level is capable of varying over time, and the regulator regulates the chamber pressure based on the baseline level.

摘要： A fluid sampling system retrieves a formation fluid sample from a formation surrounding a wellbore extending along a wellbore axis, wherein the formation has a virgin fluid and a contaminated fluid therein. The system includes a sample inlet, a first guard inlet positioned adjacent to the sample inlet and spaced from the sample inlet in a first direction along the wellbore axis, and a second guard inlet positioned adjacent to the sample inlet and spaced from the sample inlet in a second, opposite direction along the wellbore axis. At least one cleanup flowline is fluidly connected to the first and second guard inlets for passing contaminated fluid, and an evaluation flowline is fluidly connected to the sample inlet for collecting virgin fluid.
