ABSTRACT:
A fluid sampler operable for taking at least one fluid sample in a subterranean well and associated methods. A fluid sampling method includes the steps of disposing a fluid sampler at a first target location in the well, receiving the fluid sample into at least a first sample chamber of the fluid sampler, pressurizing the fluid sample in the first sample chamber using a pressure source of the fluid sampler, retrieving the fluid sampler to a surface location, isolating the fluid sample in the first sample chamber from the pressure source of the fluid sampler and supercharging the fluid sample in the first sample chamber using a pressure source on the surface.
