CO2 injection in a 2D layered brine formation

Description

CO2 injection in a 2D layered brine formation This example is from the paper: Pruess, K. et al. 2004. Code Intercomparison Builds Confidence in Numerical Simulation Models for Geologic Disposal of CO2. Energy, 29(9-10): 1431-1444. DOI:10.1016/j.energy.2004.03.077. This is a sketch scenario of CO2 injection at the Sleipner field. The problem involves a buoyancy-driven flow caused by injection of supercritical CO2 at the bottom of a formation buried at 1 km depth. The formation contains high-permeable sandstones and thin shale interlayers. Different capillary pressure curves are used for shales and sandstones. The injection results in a complicated behaviour of CO2 plume since the gas accumulates below the low-permeable shales. The injection is simulated over 2 years. Gas saturation and pressure distributions as well as parameters near the injection point should be reported. The problem can be simulated using either GASSTORE or BLACKOIL module.
