An operator has designed a demonstration project for carbon dioxide (CO2) enhanced oil recovery (EOR) and has implemented it in one of its fields. The main objectives of the demonstration project are estimation of sequestered CO2, determination of incremental oil recovery, and evaluating the risks and uncertainties involved, including migration of CO2 within the reservoir and operational concerns. It is estimated that approximately 40% of the injected CO2 will be sequestered permanently in the reservoir.
Project Design
Conceptual Road Map and Screening Studies. Given the relatively light nature of crude oils and generally high reservoir pressures in Saudi Arabia, CO2 injection is a viable recovery method, especially in flooded reservoirs.
