    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.

    摘要: A downhole drilling tool positionable in a wellbore penetrating a subterranean formation is provided. The tool includes a formation evaluation tool having fixed and retrievable portions. The fixed portion is operatively connected to a drill collar of the downhole tool. The fixed portion is for establishing fluid communication with a subterranean formation. The retrievable portion is fluidly connected to the fixed portion and retrievable therefrom to a surface location. The retrievable portion is for receiving a formation fluid from the subterranean formation.

    摘要: A sensor plug positionable in a perforation extending into a wall of a wellbore penetrating a subterranean formation is provided. The sensor plug includes a plug sleeve disposable in a perforation extending through the wellbore wall, a pin positionable in the plug sleeve a sensor and circuitry. The pin is adapted to expand the plug sleeve as it is advanced therein whereby the plug sleeve seals the perforation. The sensor plug may be deployed into the sidewall of the wellbore by a downhole tool.
