GENERAL 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.

Detailed explanation-4: -The source rocks satisfy three geochemical requirements such as quantity (amount of organic matter), quality (type of organic matter or kerogen type) and thermal maturity (extent of burial heating) (Peters and Cassa, 1994) . In this study, the quantity of organic matter was measured as TOC (wt.
