The choke manifold comprises valves and chokes for controlling the flow from the well.
During drilling, the mud is circulated through the choke manifold when the blowout preventers are closed; a choke manifold is also used to control the pressures encountered during a kick. The heavy slurry may be pumped into the well by a kill manifold to reach pressure balance. The choke manifold can be applied to well clean-up and blow-off.
