Abstract (en)

[origin: GB2581586A] An automated system for use in well control comprises a controller configured to receive an input signal indicative of a fluid flow rate or fluid volumetric rate from a wellbore. The controller is configured to determine from the input signal whether the fluid flow rate or fluid volumetric rate exceeds a preselected threshold indicative of a fluid influx condition in the wellbore system. On determining that the fluid flow rate or fluid volumetric rate exceeds the preselected threshold, the controller is configured to automatically output one or more command signals initiating an initial well control protocol.
