Abstract
A system for drilling a wellbore includes a prediction unit operable to predict a change in a drilling event while the wellbore is being drilled and prior to the drilling event change occurring. The prediction unit monitors surface and downhole data and well inflows to predict drilling events. The prediction unit may activate alarms for predefined drilling conditions, such as a kick alarm to provide an early warning of a dangerous influx of formation fluids into the wellbore.
