Stag crude is a highly naphthenic, low-sulphur crude oil which exhibits a flash point in excess of 100ºC. This property, combined with its low sulphur, very low pour point and moderate viscosity enable the crude to be used directly as a fuel oil or fuel oil cutter stock, or in the production of naphthenic lube oils. Current production of Stag crude oil is approximately 7,000 barrels per day.
