Air Injection in Light-Oil Fractured Reservoirs – A Review of Challenging Reservoir Modelling Aspects

D15 A REVIEW OF THE CHALLENGING RESERVOIR ENGINEERING ASPECTS OF MODELING THE RECOVERY FROM A LIGHT OIL FRACTURED RESERVOIR BY AIR INJECTION Abstract 1 MARURO OKAMOTO AND BERNARD BOURBIAUX INSTITUT FRANÇAIS DU PÉTROLE (IFP) 1-4 Avenue de Bois Préau 92852 Rueil Malmaison cedex France Although often considered as a thermal recovery method concerning heavy oil reservoirs air injection can be an economical IOR option for light oil reservoirs. Actually unlike other gas injection processes involving a marketable or synthetic gas the air injection method offers the main advantage of an unlimited availability for any field. However especially for fractured reservoirs
