Choke and Kill Manifold is used to control well kick and pressure. In case of well kick or blowout, Choke Manifold may control downhole pressure by valves open/close. Heavy slurry may be pumped into well by Kill Manifold to reach pressure balance. Besides, Choke Manifold can be applied to well cleanup and blow-off.
