Abstract: Embodiments of the subject technology provide for receiving real-time drilling data comprising different drilling parameters measured during a drilling operation. The subject technology calculates a kick detection parameter based at least in part on the different drilling parameters. The subject technology detects an occurrence of a kick during the drilling operation when the kick detection parameter deviates from a trend formed by previously calculated kick detection parameters. Further, the subject technology activates an alarm during the drilling operation in response to detected occurrence of the kick to facilitate preventing a blowout.
