Porphyrins in crude oil are large, complex molecules derived primarily from chlorophyll and related compounds. They are found in virtually all oils and rock extracts, with the exception of condensates that have lost their heavy ends. Porphyrins are separated by HPLC and can be analyzed by several different methods.
Example
Figure 1 shows a comparison of nickel porphyrin distributions for a source rock extract (top) and an oil (bottom) from southern Sicily. The similar porphyrin distributions for the oil and the source rock extract suggest a plausible positive correlation, which in this case was supported by other geochemical data.
