Kick refers to uninvited influx flow from the formation into the wellbore during drilling operation. Undesired event such as non-productive time (NPT) and blowout may occur if the engineers ignore the positive indications of kick. The well should be shut-in immediately and well control procedures should take place after the kick is detected. In this study, a base model has been created in the simulation software, Drillbench. Besides, two types of shut-in methods have been evaluated and studied to investigate the relationship of different shut-in methods affecting the volume of pit gain using the software. Both shut-in methods have been simulated in the case with water-based mud and oil-based mud. The results of the studies with the quantitative difference in term of the volume of pit gain between two methods is included in this paper.
