EOR CO2 project Croatia, environmental aspects

Production of residual hydrocarbons can be done by different tertiary, EOR (enhanced oil recovery) or EGR (enhanced gas recovery) methods. An EOR method largely applied on ‘depleted’ oil reservoirs is injection of carbon dioxide when a part of the produced carbon is turned back into the reservoir in the form of carbon dioxide (CO2). At the same time carbon dioxide is regarded as the primary greenhouse gas contributing to global warming and climate change. Up to our knowledge INA EOR CO2 injection project Ivanić and Žutica represents the largest onshore EOR project in Europe. Due to the significant amount of CO2 recovered from and injected into the reservoir special environmental protection measures shall be implemented in different project phases. After providing information on the EOR by CO2 injection the article delivers information on the Ivanić and Žutica EOR CO2 project, with special attention to its environmental aspects.
