Abstract

With most oil fields around the world reaching maturation it is not uncommon for oil companies to investigate the possibility of implementing CO₂ Enhanced Oil Recovery. The injection of CO₂ in a reservoir reduces the oil viscosity within the reservoir, which can later be more easily pushed towards a producing well. Computer simulators such as BOAST NFR are key tools in order to simulate the response of a reservoir to CO₂ EOR and predict oil production. This thesis investigates an example of CO₂ EOR in the Gabon Basin where such technique has yet to be implemented. Oil production has been on the decline since the late 90s and the implementation of CO₂ EOR should not be overlooked. Estimates of a possible non neglectable oil production in the Rabi-Kounga oil field can be predicted using actual physical characteristics of both oil and reservoirs. CO₂ EOR has proven to be very successful in the Permian Basin where CO₂ yet has to be brought from distant sources using an elaborate network of pipelines. In the Gabon Basin however, natural gas is readily available in great quantities which reduces the scale of infrastructures needed.
