The IEA Weyburn CO2 Monitoring and Storage Project — The European Dimension

摘要: The IEA Weyburn CO 2 Monitoring and Storage Project is a collaborative investigation involving geoscientists from North America Europe, co-ordinated by the Petroleum Technology Research Centre (PTRC) in Regina, Canada. currently analyzing effects of miscible flood into carbonate reservoir rock at mature onshore Canadian oilfield. Anthropogenic being injected as part an enhanced oil recovery operation. European contribution includes analysis long-term safety performance storage via construction features, events processes (FEP) database. This will allow integrity deep sedimentary rocks to be investigated objectively. Initial work has also been focused on better understanding pre-injection hydrogeological geochemical conditions recognize changes resulting injection . distributions are irregular reflect anthropogenic or near surface phenomena seasonal variations fluxes present. There no correlations between gas anomalies wells pipelines. Changes these baseline result under focus future activities. Geochemical experiments, predictive computer modeling, microseismic monitoring, soil surveys carried out investigate migration pathways rate extent chemical reactions with host formation adjacent strata.
