Notes: Determined by Rock Eval pyrolysis. S1 = amount of free hydrocarbons, S2 = amount of hydrocarbons generated through thermal cracking of nonvolatile organic matter, S3 = amount of CO2 produced during pyrolysis of kerogen, Tmax = temperature at which the maximum release of hydrocarbons from cracking of kerogen occurs during pyrolysis, HI = hydrogen index, OI = oxygen index, PI = production index, PC = pyrolyzable carbon, RC = residual organic carbon.
