Study of Kick Detection and Well Control Using Wait and Weight Method (Engineers Method)

This laboratory report presents a comprehensive experimental study on well control principles, kick detection indicators, and kick mitigation using the single-circulation Wait and Weight Method (also known as the Engineer's Method). Utilizing a well control simulator, the study evaluates the pressure behavior and procedural steps required to remove a formation fluid influx while maintaining constant Bottom-Hole Pressure under underbalanced wellbore conditions.The document covers key well control parameters and calculations, including Kill Mud Weight, Initial Circulating Pressure, Final Circulating Pressure, and Maximum Allowable Annulus Shoe Pressure. It details the step-by-step kill procedure across two main operational phases: the Surface-to-Bit phase, where drill pipe pressure gradually decreases from Initial Circulating Pressure to Final Circulating Pressure as weighted mud is pumped, and the Bit-to-Surface phase, where the influx is displaced through the annulus while holding drill pipe pressure constant at Final Circulating Pressure.Additionally, the report provides a multi-stage observation of casing and drill pipe pressure profiles, highlighting gas expansion dynamics, casing shoe protection, and post-kill pressure evaluation including re-kick identification and trapped pressure management. Comparative analysis with the Driller's Method is included to demonstrate the advantages of single-circulation well control in minimizing total circulation time and reducing surface casing pressures.
