Specific measurement of various parameters used to determine viability of mudrocks. These parameters include TOC (organic richness), S1 (free hydrocarbons in rock), S2 (remaining hydrocarbon potential), S3 (organic CO2), Tmax (Thermal Maturity). The new RockEval 6 has an extended pyrolysis range that allows for better characterization of the free hydrocarbons and provides a measure of the inorganic CO2).
