PhD-project title: Carbon storage in geological formations: pressure evolution and leakage in large scale multilayered systems

Carbon Capture and Storage (CCS) has shown to be one of the most promising tools in the portfolio of CO2 mitigation strategies, reducing the risk of climate change.

One of the main issues of CO2 storage projects in geological formations is to make sure that CO2 is safely contained below the surface, i.e., it is kept within a reservoir by different trapping mechanisms. However, if CCS is to become industrial standard, large amounts of CO2 have to be injected on a basin scale forcing changes in the regional pressure regime due to the quasi incompressibility of the formation water. This may lead to brine migration far beyond the local storage area where it may affect upper groundwater reservoirs. Furthermore, the moving pressure front might lead to the reactivation of faults causing potential migration pathways for brine or injected CO2.

In this context, we would like to study the pressure evolution on a basin scale and run possible leakage scenarios of CO2 or brine to investigate the impact of leakage and pressure in multilayered systems. As an example we will refer to the Northern German Basin. For this modeling study we will use and modify the petroleum systems modeling software PetroMod 11 (Schlumberger).
