Abstract
An apparatus () for obtaining fluid samples in a subterranean well (). The apparatus () includes a wireline conveyance () and a fluid sampler () supported by and positioned with the wireline conveyance () in the well (). The fluid sampler () includes an actuator () operable to establish a fluid communication path between an exterior and an interior of the fluid sampler (), a plurality of sampling chambers () operable to receive fluid samples therein and a self-contained pressure source () in fluid communication with the sampling chambers () operable to pressurize the fluid samples obtained in the sampling chambers () to a pressure above saturation pressure, thereby preventing phase change degradation for the fluid samples during retrieval of the fluid sampler () to the surface.
