Efficient high-pressure fluid sampling during well testing

The wellhead sampling manifold is a mobile sampling system for collecting high-pressure fluid samples at the wellhead during well testing operations. Six 15,000-psi conventional or single-phase bottle units are plumbed into the common manifold. Each sample cylinder has its own block and bleed valves; the drain and purge tank is common to all. The sampling line is rigged to a single sample port at the wellhead for taking up to six high-pressure fluid samples in quick succession without having to make or break high-pressure connections.
