Project information

The MOVECBM project will focus on the monitoring and verification of the CO₂ storage capacity of deep subsurface coal and possible emissions to the surface. In order to meet these goals the project addresses:

	Sorption characteristics of coal bounded by the conditions as in the investigated field test site. For example if production will be mainly contain CO2 then nearly no adsorption have been taking place and this does indicate that the coal is behaving a traditional reservoir with free CO2 gas. This has of course severe implications for the implementation of CO2-ECBM projects in the future as well as for the (long-term) HSE aspects of this type of storage.
	One of the outcomes of the EC RECOPOL project was that with the existing modelling mainly based on CBM type of modelling it is very difficult to predict the CO2 behaviour in coal. Regarding adsorption/desorption and swelling/shrinkage. Several models will be tested and upgraded.
	Monitoring and verification of the target coal layers and the caprock will be performed in order to investigate migration and possible emissions of CO2 and CH4.
	Monitoring and verification of the well through time and possible deterioration of the well as a result of the CO2. For the long-term the CO2-injection wells might be the most likely pathways from the injected coal the surface and are considered as the highest risks.
	Monitoring and verification of the near surface. Within the EC RECOPOL project a 24 months continuously monitoring is executed and is still continued. Within this monitoring only CO2 in the soil is measured. To improve this unique dataset also flux measurements and concentrations will be done including other components (Radon, CH4).
	Integrated risk assessment, public acceptance, guidelines for site certification will be addressed.
	The outcomes of this research will be used to evaluate and extrapolate the findings to other countries in Europe and outside Europe, e.g. USA., Australia and China.
In summary the objectives and activities of the MOVECBM project are:			Schematic picture of the field experiment in the RECOPOL project Poland. Within the MOVECBM project, the injection well in this picture will be used for monitoring and verification.
	To prove that the CO2 is safely stored in the coal, understand the adsorption rate into the coal matrix, where it is physically bound to the coal.
	To improve the physical accessibility to methane for optimal production.
	To improve reservoir models using field data from this pilot, resulting in better tools to analyse CO2 storage and ECBM economics in the future.
	Determine optimal monitoring for characterising migration of CO2 and CH4 in coal.
	Determine optimal monitoring for possible leakage to the surface: sides of the reservoir, through the cap rock, along the wells, from surface to atmosphere.
	Verification if the CO2 and CH4 migration is behaving as predicted from models within accepted boundaries.
The site activities are:
	Baseline monitoring of reservoir, well and surface to determine baseline situation.
	Produce back injector to determine adsorption rate of CO2 (injector as used in the RECOPOL project).
	Dewatering near producing well.
	Time-lapse monitoring.
Other activities in the project are:
	Integration of results.
	Site certification and standardisation.
	Dissemination and knowledge transfer.
