Control system for use in drilling an oil and gas well, namely, fluid and pressure measurement devices used to confirm that a fluid influx event has occurred after a blow-out preventer has closed the wellbore and conduit and valving arrangements to safely regain well control by circulating the fluid influx out of the well through a chokeline while maintaining the pressure inside the wellbore between fracture and pore pressures
Electrical and Scientific Apparatuswell control services used during the drilling of an oil and gas well, namely, confirming that a fluid influx event has occurred after first closing the well to atmosphere with a blow out preventer by using fluid flow and pressure measurement devices, and using conduit and valving arrangements to safely regain well control by circulating the fluid influx out of the well through a chokeline while maintaining the pressure inside the wellbore between fracture and pore pressure
