Choke Manifold - Well Testing Choke Manifold
Choke manifold is a system of valves and chokes for controlling the flow from the well usually has two flow paths, one adjustable choke used primarily for cleaning the well up and facilities to install and change choke of fixed sizes for a more accurate flow control during main well flow periods.
Each flow path has two closing gate valves which are used to direct the flow through either of the chokes or the chokes or the bypass and to provide isolation from pressure when changing the fixed choke. A dual isolation, double block and bleed valve arrangement is recommended for high pressure, sour gas and sand frac clean ups.
Choke manifold is used during well testing,. The positive choke has a fixed diameter and the size of the orifice on the adjustable choke can be varied. In addition the adjustable choke allows fixed chokes to be switched out as needed without stopping the well, increasing the flexibility of the overall system.
