Determine whether uranium decay in uranium-rich source rocks generate petroleum earlier or with different compositions.

Lewan GeoConsulting has found that early paleozoic rocks Older than 400 Ma with Uppm/TOC wt% ratios geater than 10 like the Alum Shale of Scandinavia do show signs of radiation damage with lower expelled condensate-like oil yields, and kerogen atomic H/C ratios. Radiation does not enhance timing or quantity of oil generation.
