Abstract
A method for collecting a non-pressurized sample of fluid from a well is disclosed and an illustrative sampler for performing the method is shown comprising two elongated sampler chamber interconnected upper and lower valves wherein the upper valve is mounted externally of the chamber and has a vent therein for providing less internal fluid drag in the chamber for improved and faster purging, filling, without subjecting the fluid to high shear rates, and emptying of the sample chamber and for ensuring a non-pressurized true representation sample upon arrival at the surface.
