Conclusions‣Future oil increasingly dependant on IOR/EOR‣Strong cost pressures‣Applications of modern technology (multilaterals,smart wells)‣Efficient reservoir management required‣Look for innovative ways continuing(research)‣Fiscal incentives & environmental pressuresmay steer direction
Conclusions•The forces holding back the oil in the porous rock are theinterfacial tension between oil and water, and the viscosity ofthe crude oil.• EOR has been utilized to overcome or to minimize thephysical and geological effects to mobilize additional oil.• It’s usually applied after primary and secondary recovery.• There is no universal method to be applied in any reservoir•Certain reservoir and fluid parameters have to be consideredby selecting any EOR methods• Improvement of EOR can be achieved in conjunction withother advanced technologies, such as horizontal drilling etc…
