The Evaluation of an Immiscible-CO2 Enhanced Oil Recovery Technique for Heavy Crude Oil Reservoirs

Sequestration of CO2 in enhanced oil recovery applications has been widely recognized as one of the favorite techniques for reducing emissions of CO2 into the atmosphere in response to global climate change. This technique provides lower costs for CO2 sequestration by means of higher incremental oil recoveries. There are some key parameters, when considering a.field for the CO2 displacement. Oil reservoirs are screened out according to oil gravity, reservoir temperature and pressure, minimum miscibility pressure, and remaining oil saturation. Throughout this study, the CO2-Prophet tool is utilized in order to assess suitability of Batt Raman and camurlu crude oil fields for CO2-enhanced oil recovery application. In the second part of the study, the Kinder Morgan Scoping economic model is used to see economic consequences of the project. Although the API gravity and minimum miscibility pressure for these fields do not meet the required criteria for the miscible flood, due to importance of CO2 sequestration and absence of appropriate fields for CO2-enhanced oil recovery implementation in Turkey, these.fields can be considered for CO2-enhanced oil recovery applications as long as the project is economically feasible.
