Single phase fluid sampling apparatus and method for use of same

An apparatus for obtaining a plurality of fluid samples in a subterranean well comprising:

• a carrier having a longitudinally extending internal fluid passageway and a plurality of externally disposed chamber receiving slots;
• and
• a plurality of sampling chamber assemblies each including at least two sampling chambers and a pressure source, each of which is positioned in one of the chamber receiving slots of the carrier, each of the pressure sources comprising pressurized nitrogen,
• wherein the sampling chambers of each sampling chamber assembly are selectively in fluid communication with the pressure source of that sampling chamber assembly such that the pressure source of each sampling chamber assembly is operable to pressurize each of the sampling chambers of that sampling chamber assembly.

A method for obtaining a plurality of fluid samples in a subterranean well, the method comprising the steps of:

• positioning a fluid sampler in the well;
• simultaneously obtaining a fluid sample in at least two of a plurality of sampling chambers of the fluid sampler, wherein a first portion of each of the fluid samples is obtained in a debris chamber;
• and
• pressurizing each of the fluid samples using a pressure source of the fluid sampler that is in fluid communication with each of the sampling chambers.
