202 - PVT SEPARATOR SAMPLING

QuarterBack offers PVT Separator Sampling as a mean to take representative samples of the oil and gas phases from the separation unit. This type of separator sampling is aimed at recreating the reservoir fluid composition by recombining gas and liquid samples using the separator pressure, temperature and GOR to determine the amount of gas and liquids going in to the mixture. The PVT results and phase compositions are used in reservoir and PVT simulation programs and will form the basis for the design of processing plant.

The PVT oil and gas samples are transferred under pressure from the separator oil and gas outlets. These samples shall be identical to the separator fluids in terms of composition and physical properties. This method is often used to create a back-up set of PVT data that can be used to validate bottom hole or wellhead samples, or as an economical means to check an already known reservoir composition. For high quality recombinationsampling the only methods in use in the industry are Vacuum replacement for gas, and Positive Displacement (Piston Cylinders) for oil.
