Gas Kicks During Drilling : Comparison between Oil and Gas Wells

Abstract

This dissertation presents a comparative analysis of well control strategies in two hydrocarbon wells—one producing gas and the other oil. The first part provides a theoretical foundation, covering essential drilling operations and well control concepts, including kick detection and management techniques. The second part applies this knowledge through the practical examination of two real-world kicks. The gas well was controlled using the bullheading method, due to lost circulation, while the oil well used the driller’s method, based on maintaining bottomhole pressure. The study emphasizes how formation behavior, influx type, and well conditions influence the selected control method. It highlights key lessons in early detection, equipment use, and tailored procedures for improving well integrity and operational safety.
