    Abstract: Methods for operating multi-probed formation testers to determine a fluid density gradient in the formation. The probes of the multi-probed formation tester are connected to a pressure gauge through a flowline that establishes a differential height between the probes. In some embodiments, a gradient of the fluid density in the flowline is determined as a function of the gradient of fluid density in the wellbore. The flowline fluid density gradient is then used to determine a formation fluid density gradient as a function of the flowline fluid density gradient.

    Abstract: A check valve (100) includes a closure member (112), primary (114) and secondary (116) sealing elements, and a spring (110) that urges the closure member (112) into engagement with the primary sealing element (114). The primary sealing element (114) is retained by a groove (126) formed by the housing (102) and the secondary seal element (116). Increasing pressure acting on the closure member (112) compresses the primary sealing element (114) and allows the closure element (112) to engage the secondary sealing element (116). As it compresses, the primary sealing element (114) wipes contamination from the closure member (112) to provide a clean surface for engagement with the secondary sealing element (116). The secondary sealing element (116) also provides redundancy, which is especially beneficial in gas sealing applications.

    Abstract translation: 止回阀（100）包括封闭构件（112），初级（114）和次级（116）密封元件，以及促使封闭构件（112）与主密封元件（114）接合的弹簧（110） 。 主密封元件（114）被由壳体（102）和辅助密封元件（116）形成的凹槽（126）保持。 作用在封闭构件（112）上的增加的压力压缩主要密封元件（114）并且允许封闭元件（112）接合第二密封元件（116）。 当主密封元件（114）压缩时，主要密封元件（114）从封闭元件（112）上擦去污染物以提供用于与次密封元件（116）接合的干净表面。 二次密封元件（116）还提供冗余，这在气体密封应用中特别有益。

    Abstract: A single phase sampling apparatus and method for retrieving a formation fluid sample at or above the bubble point of the sample. The apparatus utilizes a gas charge contained between a sample piston (1) and a charging piston (3) to maintain a formation sample at the desired pressure. The charging piston utilizes the hydrostatic pressure present at the depth of the desired formation sample to compress and therefore increase the gas charge to the appropriate pressure necessary to maintain the formation sample at the desired pressure. The utilization of hydrostatic pressure to increase the pressure of the gas charge allows the use of a low pressure gas charging system to prepare the apparatus prior to sampling, thereby increasing the safety and ease of use of the device.

    Abstract: A formation testing tool is described herein, including a formation probe assembly having an extendable sampling probe (96) surrounded by a cylindrical sleeve (94). The sleeve is configured to engage a metal skirt (145) having an elastomeric seal pad (40) coupled thereto. The skirt and seal are configured to be field replaceable. The elastomeric pad has a non-planar outer surface which engages a borehole wall in preparation for formation testing. The seal pad may be donut-shaped, having an aperture through the middle of the seal pad. The seal pad and its surface may include numerous different embodiments, including having a curved profile. The seal pad may also include numerous different embodiments of means for coupling the seal pad to the metal skirt. The formation testing tool also includes formation probe assembly anti-rotation means, a deviated non-circular flowbore, and at least one closed hydraulic fluid chamber for balancing fluid pressures.
