WellCTRL Engineering provided a valued client with a comprehensive analysis of CO2 trapped pressure buildup in wellhead equipment for carbon capture and storage (CCS) operations. The analysis, which included a detailed study of CO2 fluid expansion during the shut-in period, left no stone unturned in understanding the additional stress load on the wellhead equipment.
WellCTRL Engineering, in a unique approach, combined CO2 phase behavior and transient flow models to determine the initial flow conditions in the surface equipment during the CO2 injection operation. This innovative method enabled the simulation of shut-in operations and the determination of the condition of trapped CO2 in the wellhead components, as well as pressure buildup as the injection temperature reached ambient temperature, thereby achieving the project’s objective. The comprehensive analysis provided by WellCTRL Engineering played a crucial role in assisting the client in evaluating the associated risk with trapped CO2 in the wellhead equipment. By identifying potential equipment failures at the surface, the analysis also guided the client in implementing effective mitigation strategies.
