... are presented and discussed. The surfactant design used in this work in fully described in a previous work ( Al-Murayri 2018 ). The scope of this work includes 4 coreflood experiments; hereafter named CF#1, CF#2, CF#3 and CF#4. On the one hand, CF#1 and CF#2 are conducted in absence of crude oil, while CF#3...

... with deionized water for 3 hours using a vacuum pump. Then at least 4 pore volumes of deionized water were injected to measure the initial permeability of the cores and fully stature them with water. The cores were then saturated with the crude oil by pumping at least 5 pore volumes of oil through the cores...
