Study of Kick Detection and Well Control Using the Driller's Method.

This laboratory report presents an experimental study on well control principles, kick detection indicators, and kick mitigation using the conventional Driller's Method. Using a well control simulator, the study analyzes the pressure dynamics required to safely remove a formation influx while maintaining constant Bottom-Hole Pressure (BHP) under unbalanced conditions where formation pressure exceeds hydrostatic pressure.The report covers early kick indicators such as pit gain, flow with pumps off, rate of penetration changes, and drill pipe and casing pressure variations. It details the two-circulation process of the Driller's Method: the first circulation circulating out the kick using original mud weight while keeping drill pipe pressure constant at Initial Circulating Pressure through choke adjustments, and the second circulation displacing the original mud with weighted kill mud to restore complete hydrostatic balance, reducing drill pipe pressure from Initial Circulating Pressure to Final Circulating Pressure.
