Weight % Sulfur

The weight % Sulfur for a given oil is another common ‘bulk property’ and can reflect the oil’s source and quality. Sources containing low concentrations of free iron (i.e. carbonate source rocks) frequently produce oils rich in sulfur. Typically, the amount of sulfur in oils usually decreases with increasing thermal maturity and increases as a result of bacterial degradation. The % Sulfur content is independent of H2S content of an oil sample.
