Sweet crude oils are low in Sulphur below 0.5%wt and require less processing to meet product specifications
Examples: Brega Condensate, Dulang, Njord
Sour crude oils have a higher Sulphur content typically above 1%wt and will require more processing in a refinery.
Examples: Bow River, Kuwait Export, Maya
Light crude oils have a high API gravity >35, they will produce more of the value products such as gasoline, kerosene and diesel.
Examples: Asgard Condensate, Copper Basin, Kerapu.
Medium crude oils API around 26 to 35 will produce less of the value products
Examples: Flotta, Bonny Light, Oman
Heavy crude oils API <26 produce more residual fuel which is low value compared to gasoline, kerosene and diesel.
Examples: Wabasca Heavy, Captain, Jubarte.
A Sweet Light crude oil would be of highest value.
Examples: Arab Super Light, Kutubu, Beatrice
Synthetic Crude oils are produced when bitumen or extra heavy crude oils are ‘pre-processed’ to produce a lighter, lower Sulphur crude oil.
Examples: Suncor OSH, Hamaca, Premium Albian Synthetic.
