The Possibility of CO2 Pipeline Transport for Enhanced Oil Recovery Project in Poland

Enhanced oil recovery schemes involve the transportation of large volumes of carbon dioxide from the capture source to the utilisation site. This research presents the possibilities of carbon dioxide transport using pipeline from the selected emission point to the oil reservoir located in Poland where greenhouse gas can be used as injecting fluid to improve oil production. In the first step, the different CO2 thermodynamic states are analyzed. For the design purpose, length, operating pressures and flow rates are determined, then pipeline diameter is calculated. Furthermore, the pipeline transmission schemes for CO2 transport are proposed. The study revealed, that the large amount of CO2 produced at source power plant can be transported to the oilfield site more efficiently when CO2 is converted into the liquid state. As a result, the smaller pipeline diameter can be applied for the transmission. Moreover, temperature decrease is observed when CO2 is transported in gaseous state and temperature increase is present when CO2 is in the liquefied state.
