carbon chains can occur. At the same time, most of the sulfur compounds in the oil are broken down. Therefore an ‘old-deep’ crude oil has low viscosity, low density, and very low sulfur content. This combination of properties makes the old-deep crudes the most desirable: they require little refining to remove sulfur and they can be ...
