Well control systems and associated methods
First Claim
1. A well control method, comprising the steps of:
- drilling a wellbore; and
predicting a change in flow between the wellbore and a reservoir prior to the change occurring, the predicting step being performed during the drilling step, and the change in flow occurring during the drilling step.

Abstract
Well control systems and associated methods. A well control method includes the steps of drilling a wellbore and predicting a change in flow between the wellbore and a reservoir prior to the change occurring, the predicting step being performed, and the change in flow occurring while drilling. Another well control method includes the steps of: sensing at least one first drilling operation variable while drilling a wellbore, thereby generating first sensed variables; sensing at least one second drilling operation variable while drilling the wellbore, thereby generating second sensed variables; and training a predictive device, using the first and second sensed variables, to predict the second drilling operation variable at a selected time.
