Matching Pressure Measurements and Observed CO2 Arrival Times with Static and Dynamic Modelling at the Ketzin Storage site

At the Ketzin pilot site 67,000 tonnes of CO2 were injected between 2008 and 2013 into a sandstone formation. Pressure monitor- ing and observation of CO2 arrival in two observation wells provide valuable field measurements for history matching. Modelling of the CO2 injection faces several challenge...

Description
Summary:At the Ketzin pilot site 67,000 tonnes of CO2 were injected between 2008 and 2013 into a sandstone formation. Pressure monitor- ing and observation of CO2 arrival in two observation wells provide valuable field measurements for history matching. Modelling of the CO2 injection faces several challenges and uncertainties as discussed in this study. Different approaches towards matching the observed data are presented. It can be shown that a calibration of the simulation models (ECLIPSE E100 and Dumux) to the data is possible with good accuracy, while considerable uncertainties in the model parameters remain, to a large amount resulting from strong correlations between permeability and porosity.
