oa Investigating Intermittent Injection of CO2 using Tough/T2Well Codes

This study was a part of an investigation into the feasibility of the concept “direct injection from the ship” for offshore CO2 storage. Reconciling the technical CO2 tanker’s outlet parameters to the well and reservoir conditions was the basis of this modelling work. Using such a model, we were able to provide the necessary input into the ongoing “safe operation evaluation”. Identifying and locating the thermal effects and the phase behavior, determining the injection potential and a sustainable well flow rate, estimating the pressure and temperature throughout the system during flow and shut-in periods, were all parts of this investigation. A coupled well-reservoir code able to capture most important thermo-physical aspects of the fluid flow has been applied to a given case study.
