Quantitative Characterisation at Smeaheia for Co2 Storage: Application to Real Dataset

This work proposes a workflow for baseline quantitative characterisation at Smeaheia, a possible candidate for future phases of the Norwegian full-scale CCS project. Geophysical and rock physics characterisation are performed to quantify key rock physics properties for the storage complex. A two-steps inversion workflow combining geophysical inversion and rock physics inversion is introduced and applied to derive 2D sections describing properties like porosity and bulk moduli with their associated uncertainties. The derived properties can be very useful for constraining reservoir modelling and for the design of a cost-efficient monitoring plan ensuring both conformance and containment.
