Abstract

Systems and methods for automated fluid sampling for tracer testing are described. In one aspect, an automated fluid sampling system includes a pressurized line, such as a production well or an injection well connectively and a fluid separation vessel receiving sample fluids therefrom. The fluid separation vessel includes a plunger and is configured for gravity-mediated phase separation of the sample fluids into a plurality of aqueous, organic and/or gas phase fluid fractions and includes pluralities of inlet and outlet ports for mediating flow of sample fluids therethrough. At least one purging fluid source, such as a gas or liquid, is used for driving the plunger. Sample fluid collection vessels receive phase-separated sample fluids from the fluid separation vessel. Pluralities of fluid lines and solenoid valves operatively link the pressurized line, purging fluid sources, sample fluid collection vessels, and disposal vessel to one another, whereby a controller selectively manages the automated flow of fluids through the various fluid lines.
