Influence of temperature and interfacial tension on spontaneous imbibition process

“Spontaneous imbibition is a mechanism that can significantly contribute to the production rate and final oil recovery in fractured and stratified reservoirs. This mechanism is affected by rock and fluid properties and it has been reported by several authors to be strongly dependent on interfacial t...
