Question

Classification of kerogen is based on the relative amount of Carbon (C), Hydrogen (H) and Oxygen (O).
Which ONE of the following options is CORRECT about Type II kerogen?

• A. It is low in aliphatic compounds and H:C ratio \(<0.84 \)
• B. It is rich in aliphatic compounds and H:C ratio \(<0.84 \)
• C. It is low in aliphatic compounds and H:C ratio \(>1.0 \)
• D. It is rich in aliphatic compounds and H:C ratio \(>1.0 \)

Hint:

For kerogen classification, focus on the H:C ratio. Type II kerogen is typically more hydrogen-rich, which contributes to its potential for generating oil.

Answer 1

The Correct Option is D

Kerogen is classified based on its chemical composition, particularly the ratio of Carbon (C), Hydrogen (H), and Oxygen (O).
Type II kerogen is typically rich in aliphatic compounds and has a high H:C ratio. Specifically, Type II kerogen has an H:C ratio greater than 1.0, indicating it is more hydrogen-rich compared to Type I kerogen.
Therefore, the correct classification for Type II kerogen is that it is rich in aliphatic compounds and has an H:C ratio greater than 1.0.
