Transient Flow Modelling of Start-up CO2 Injection into Highly-Depleted Oil/Gas Fields

Revelation J. Samuel and Haroun Mahgerefteh
Abstract—Carbon Capture and Storage (CCS) represent a promising technology in mitigating global warming challenges. In this study, we developed a model for the numerical simulation of the highly transient phenomena taking place in a wellbore during start-up CO2 injection operations. The basic conservation equations are considered in the tubing. The wall friction factor and heat transfer coefficient between the fluid and the surrounding formation are also taken into account. The simulation results obtained show a significant drop in pressure and temperature at the wellhead during CO2 start-up injection. This is a serious safety concern and poses several risks, including hydrate and ice formation with interstitial water around the wellbore and thermal shocking of the wellbore casing steel and thus in response, ways of minimising its occurrence are recommended.

Index Terms—Depleted oil/gas reservoir, carbon storage, modelling, start-up injection, transient flow.
