Joint Inversion for Improved CO2 Monitoring at the Ketzin Pilot Site, Germany

In this paper we present the joint inversion method, its implementation, and first results of the application using synthetic FWI and ERT data sets for a realistic Ketzin model. This synthetic model was designed to capture the main features of the geology at the Ketzin pilot site and includes a hypothetical CO2 distribution, based on reservoir modelling. Our goal is to improve imaging and quantification of the injected CO2 at the Ketzin pilot site, as well as to improve knowledge about CO2 storage at Ketzin. Using real field data, we aim to mature the joint inversion technology further towards large-scale CO2 storage applications.
