Low Salinity Oil Recovery – The Role of Reservoir Condition Corefloods

C18 LOW SALINITY OIL RECOVERY – THE ROLE OF RESERVOIR CONDITION COREFLOODS Abstract 1 There is much published data in the literature showing that waterflood recovery is dependent on the composition especially the salinity of the injection brine. These data however have all been generated at conditions which are not representative of the reservoir and therefore it has not been demonstrated that these potential EOR benefits are applicable to real reservoir situations. Reservoir condition coreflood studies using live crude oil and brine were therefore performed on a number of different reservoir systems to determine whether the recovery benefits seen in
