Carbon dioxide injection into depleted oil fields is widely used. The injection enhances oil recovery and generates other advantages like: (1) decrease of carbon dioxide concentration in the atmosphere and (2) the possibility for CO2 emission trade. Geological and reservoir parameters of Jastrząbka Stara structure are discussed in this paper in the context of possible CO2 sequestration. Reservoir absorptivity and tightness, overburden thickness, storage capacity as well as social and economical aspects are taken into consideration. Based upon these factors, Jastrząbka Stara oil deposits may be classified as potential carbon dioxide storage site.Detailed data cannot be published due to Polish Oil and Gas Company (PGNiG SA) confidentiality requirements.
