Title:
APPARATUS AND METHOD FOR WELL FLUID SAMPLING
Document Type and Number:
WIPO Patent Application WO2000034624
Kind Code:
A3
Abstract:
There is disclosed a well fluid sampling tool (5) and related well fluid sampling method. A number of problems exist with known single phase sampling tools, e.g. the length and outer diameter of the tools. Accordingly, the present invention provides a well fluid sampling tool (5) having, at least in use, a sample chamber (315) at least partly contained within an at least partially evacuated jacket (160, 165, 170), and outermost wall (160) of the jacket (160, 165, 170) being adjacent to or forming an outermost wall of the tool (5). In such a tool (5) the evacuated jacket (160, 165, 170) acts to maintain the sample as originally retrieved, e.g. in single phase form (at original temperature).
