The Effect of Nickel, Vanadium, Asphaltene, NSO and Sulfur on Crude Oil Quality

The Mishrif reservoir (Cenomanian - Turonian) in the Z, H, B and N oilfields southern Iraq was investigated to clarify how nickel, vanadium, asphaltene, NSO sulfur content affect crude oil quality. GC-Mass ICP-MS analyses were used provide fruitful hydrocarbon results. Classification of based on API gravity broadly indicates oil's density general properties. Typically, lighter oils are easier refine, yield higher percentages valuable products such as gasoline diesel, have a market value. Heavier require more processing may residual products, heavy fuel asphalt. classified medium sour containing high (%) Z oilfield (5.22), H (5.1), (5.12); significant than those oil, which is sweet less 5% sulfur. NSO, vanadium affects quality price because its negative impact refining processes, susceptibility corrosion, environmental damage later after consumption burning.
