Managing Over-pressure in Deep Saline Aquifer Storage of CO2

One of the main challenges facing industrial scale storage of CO2 in saline aquifers will likely arise from pressure build up in the storage formation and displacement of brine. The study presented here examines two mitigation strategies for limiting the rate and magnitude of over-pressure development by producing and re-circulating brine in the storage system. The analysis is performed using a reservoir modelling tool applied to a multi-aquifer storage system.
