MOVECBM
The objective of the EC MOVECBM project is to improve the current understanding of CO2 injected in coal and, hence, the migration of methane thus ensuring a long-term reliable and safe storage. In the MOVECBM project modelling and laboratory work are performed that will be based on parameters of the previously investigated test site in Kaniów, Poland by the EC RECOPOL project. However, the former CO2 injection well from the RECPOL project will now be used to produce gas from the coal seams in order to improve the CO2 storage and ECBM understanding. The composition of this gas will be contineously monitored to define the actual adsorption of CO2 that was injected in the period August 2004 till June 2005 in the coals seams during this RECOPOL project. Besides the field production test in Kaniów, a small scale combined injection and production experiment will be carried out in the Velenje coal mine in Slovenia. Here, in the coal, horizontal injection and production wells are used to investigate adsorption, desorption and migration processes for local coal conditions. The results from the mine is expected to provide the missing information between the larger scale field experiment in Kaniów and the laboratory work.
The above mentioned experiments will allow to test optimal storage and production regimes, but also the corresponding optimal monitoring methodology. Besides the coal reservoir and the cap rock also the wells and the (near) surface are monitored. Monitoring and verification guidelines for site certification are derived from modelling results and compared to broadly accepted standards.The MOVECBM project started in November 2006 and has a duration of 2 years.
