Abstract
Killing a well by diverting flow in a drilling fluid circulation system to maintain kill mud pressure in a discharge piping during the well kill operation. It is determined that a target pressure of the kill mud in the discharge piping is not satisfied by a pressure of the kill mud discharged by a pump into the discharge piping. In response, a pressure of the kill mud is adjusted by at least partially opening a pressure control device to release kill mud into a bypass piping.
