Determining The Optimal Amount Of Sulfate Ions In Enhanced Oil Recovery By Smart Water

Almost half of the discovered oil are in carbonated reservoirs which are more like fractured reservoirs.Oneof the most emergedpractical methods in these domain is the sea water injection method. So far, fewresearchers have been able to increasethe amount of oil recovery from the reservoir by reducing the saltconcentration,inactive ions and increasing the active ion concentrate. In this study, it s been tried todetermine the optimizedamount of the sulfate ion which is the main active ion.Hence the zeta potentialtests, spontaneous imbibition and contact angle for different concentrations of these ions were designed.As a result, the optimal amount of sulfate ions in the smart water was observed four times more thansulfate.
