  • Wireline conveyed single phase fluid sampling apparatus and method for use of same
    Patent number: 8429961
    Abstract: An apparatus (10) for obtaining fluid samples in a subterranean well (14). The apparatus (10) includes a wireline conveyance (22) and a fluid sampler (12) supported by and positioned with the wireline conveyance (22) in the well (14). The fluid sampler (12) includes an actuator (24) operable to establish a fluid communication path between an exterior and an interior of the fluid sampler (12), a plurality of sampling chambers (26) operable to receive fluid samples therein and a self-contained pressure source (28) in fluid communication with the sampling chambers (26) operable to pressurize the fluid samples obtained in the sampling chambers (26) to a pressure above saturation pressure, thereby preventing phase change degradation for the fluid samples during retrieval of the fluid sampler (12) to the surface.
