Monitoring techniques applied for CO2 injection in coal
conference paper
To demonstrate that CO2 injection in coal under European conditions is feasible and that CO2 storage is a safe and permanent solution and that coal bed methane can be produced in the same process, the EC funded RECOPOL project is being carried out. In order to improve the understanding of storage in coal, to verify that safety and environment are not jeopardised, and to determine that the CO2 is injected into the intended coal layers an extensive monitoring programme is applied. This monitoring programme is based on FEP analyses and aims at different parts of the subsurface and the wells. Monitoring results, e.g. soil gas, composition of produced gas and water, crosswell seismic acquisition and isotope signature analysis are discussed. The measured data before and during injection contribute to a dynamic subsurface model that is used to predict future behaviour of the stored CO2 and possible depletion pathways.
