Kill Manifold

Kill manifold is necessary equipment in well-control system to pump drilling fluid into well barrel or inject the water into wellhead. It consists of check valves, gate valves, pressure gauges and line pipes.

In case of increase in well head pressure, the kill manifold can provide a means of pumping heavy drilling fluid into the well to balance bottom hole pressure so that well kick and blowout can be prevented. In this case, by using blow down lines connected to the kill manifold, the increasing well head pressure also can be released directly for bottom hole pressure release, or water and extinguishing agent can be injected into the well by means of the kill manifold. The check valves on the kill manifold only allow injection of kill fluid or other fluids into the well bore through themselves, but don't allow any back follow so as to perform the kill operation or other operations.
