Q. Typical parameters obtained in the pyrolysis experiment of the source rock materials are shown in the Figure. Which one of the following is NOT true about pyrolysis in source rock analysis?

A. Peak S1 represents volatilization of existing hydrocarbons.

B. Peak S2 represents breakdown of kerogen and generation of hydrocarbons.

C. Peak S3 represents Tmax, the temperature at which most hydrocarbons are generated.

D. S1/(S1+S2) represents the production index.

Ans: Peak S3 represents Tmax, the temperature at which most hydrocarbons are generated.

Sol:
