aCQurate – Accurate CO₂ monitoring using quantitative joint inversion for large‐scale on‐shore and off‐shore storage applications

The ACQurate project will be based on collaboration around “field research station” (FRS) in
Canada expand data base for inversion with electromagnetic data (CSEM), gravimetry data as well as geological structure data. By combining petrophysical and structural data, the goal is to be able to obtain quantitative estimates for reservoir data. Specifically, one wants to be able to better distinguish between effect of pore pressure and CO₂ saturation. The goal is further to restructure software so that the method can be used large-scale CO₂ storage.

The project builds on the method for “Structural joint inversion” which was developed on the basis of The Ketzin / Complete project (234610), in collaboration with the German research center for geoscience (GFZ). IN “Structural joint inversion” combines seismic data and electrical resistivity tomography (ERT).

At FRS, CO₂ injection will be carried out at shallow depths (below 1000 m) to study how
CO₂ migration can be mapped at different depths. The work is based on two injection wells and a series monitoring wells as well as installation of measuring instruments in wells and access to core data.

Collaboration with FRS in the applied project represents a unique opportunity to further develop the joint inversion technology in a realistic field environment and with access to “state of the art” measurement methods. Through the project, Sintef will collaborate with Canadian and American research communities that represent cutting-edge expertise in the respective measurement methods.
