Wellhead Sampling Manifold

The wellhead sampling manifold (WSM) is a mobile sampling system designed for safe, efficient high-pressure fluid sampling at the wellhead during well testing operations. The WSM holds six 103-MPa [15,000-psi] conventional sample bottle or single-phase sample bottle units that are plumbed into a common high-pressure sampling manifold. The manifold has individual block and bleed valves for each sample cylinder and a common drain-and-purge tank. The sampling line is rigged to a single sample port at the wellhead and allows up to six high-pressure fluid samples to be taken in quick succession without making or breaking high-pressure connections.
