A method for processing shale oil to remove both nitrogen and impurities such as arsenic and/or selenium while minimizing such removal costs which comprises fractionating the shale oil feet to form a first naphtha cut which essentially boils at or below 350 DEG F and a gas oil cut which essentially boils above 350 DEG F, hydrotreating the first naphtha cut, separately removing a substantial amount of said impurity from the gas oil cut and then hydrotreating the gas oil cut. Thereafter the hydrotreated gas oil cut is fractionated to form a second naphtha cut which essentially boils above 380 DEG F and at or below 450 DEG F and has a high nitrogen content, and hydrotreating the second naphtha cut to reduce the nitrogen content.
