Hydrocarbon kicks remain a significant operational challenge in drilling, potentially escalating to blowouts if not detected and controlled on time. Accurate modeling of kick dynamics is essential for refining existing well control methodologies and equipment. The presented methodology integrates advanced computational fluid dynamics (CFD) and precision modeling to create a simulation model that closely mirrors the real-world behavior of a hydrocarbon kick. The model’s spatial configuration is generated in a three-dimensional domain and discretized into finite-volume cells. Emphasis is placed on the kick influx zone, where a refined mesh topology is employed. Multiphase flow models are used to describe the fluid flow in the wellbore. These models account for the interactions between the different phases, such as mass transfer, slip, and relative velocities. Equations of State, such as Peng Robinson or Soave–Redlich–Kwong, determine fluid properties based on varying pressure and temperature profiles. This information is then used in the momentum transport model to calculate the fluid velocity and pressure distribution. The turbulence and heat transfer effects are also considered to determine the flow patterns, pressure drops, and temperature profiles. Given the computational demands of such a complex simulation, high-performance computing and parallel processing are deemed essential, with a tier-2 GRID supercomputing center recommended for execution. As a result, the output provides parameters such as velocity and pressure distribution, fluid properties, and information on the flow patterns along the wellbore. All the parameters are visualized in three-dimensional space to better analyze the kick behavior. The accuracy of the simulation output is validated using the DS-5000 Scientific Drilling Simulator, where the simulation results are used as input parameters. A lab-scale mockup drilling system can be created as a final step to debug the model and revalidate the results. The proposed methodology provides a holistic approach to simulate a hydrocarbon kick and contributes to developing safer drilling practices and timely response methodologies.
