GEOLOGY

Detailed explanation-1: -Rock Eval pyrolysis S1 = the amount of free hydrocarbons (gas and oil) in the sample. S2 = the amount of hydrocarbons generated through thermal cracking of nonvolatile organic matter. S3 = the amount of CO2 (in milligrams CO2 per gram of rock) produced during pyrolysis of kerogen.

Detailed explanation-2: -Tmax is the temperature at which the maximum rate of hydrocarbon generation occurs in a kerogen sample during pyrolysis analysis. The S2 peak represents the rate of hydrocarbon generation (the area under the curve represents the amount).

Detailed explanation-3: -Tmax, which is the temperature at which the rate of hydrocarbon generation is at its maximum during pyrolysis (25 °C/min), is used mainly as a thermal maturity parameter.
