Well fluid from individual producing wells can be routed to the Test or Production Header from Individual flow lines. During production, the flow from the well is diverted into the Production Header. A provision is provided for performing testing of individual well through the Test Header. This can be facilitated through an MPFM (Multi Phase Flow Meter). Pressure and Temperature gauges are provided on the Header to monitor the pressure on the Manifolds. Provision for corrosion inhibitor injection shall be made available at the individual flow arm or at the production/ test headers if sour contents are present in the well fluid. The Crude oil from the Production Header is sent to the two stage Production Separators for bulk gas/liquid/liquid separation.
