Surface Sampling

Representative fluid sample collection at the surface

Surface sampling from the wellhead, separator, and stock tank is performed during most surface well tests. When separator recombination samples are the only available representative samples, the accuracy of the separator flow rate measurements and stability of separation conditions are especially critical to the accurate determination of reservoir phase behavior from the recombined fluids.
