APPARATUS AND METHOD FOR COLLECTING A REPRESENTATIVE FLUID SAMPLE

摘要

An apparatus for collecting a fluid sample from a reservoir contains a sample gathering chamber, a motor driven hydraulic pump, a motor mechanically coupled to the hydraulic pump, an electronic controller for influencing the actions of the motor, and a power source for running the motor. A piston which is sealably and movably disposed may be located within a tubular portion defining the sample gathering chamber. The apparatus may also further contain a metering component for regulating pressure.
