Abstract:
Gas gathering systems are essential components of the energy industry, facilitating the transport of natural gas from production sites to processing facilities. However, the presence of hydrate, solid ice-like compounds that form in pipelines and wellbore under specific conditions poses operational challenges. The study aims to address these challenges by exploring the utilization of wellbore design to prevent hydrate formation and optimize efficiency. Python Simulation and Microsoft Excel Software were employed to achieve the specific objectives of this study. The study began by investigating hydrate formation conditions, revealing an unexpected nonlinear relationship between temperature and pressure. The kinetics of hydrate formation unveiled the effects of different nucleation rates, emphasizing the importance of timely prevention. Utilizing Langmuir adsorption isotherm, the hydrate inhibition graph showcased the link between inhibitor concentration and prevention efficiency. Wellbore insulation, pressure drop, wellbore flow profile, and efficiency improvement ratio were analyzed comprehensively. Findings showed the significance of well-designed insulation, optimal flow rates, and efficient wellbore geometry on the improvement of gas gathering system efficiency. This study can be used as a guide for preventing hydrate formation in a gas gathering system using wellbore optimization.
