Actually, Brent average $59.23 per barrel for the first 30-days of 4Q'17 and may eventually end the quarter between $59.75-$60.75 in my opinion. Assuming a 1$ discount to Brent (this is what EGY got in 3Q'17) I will base my calculation on EGY Oil price at $59.25 or 16% higher than the third quarter.
