Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Decide the quality of source rock.TOC = 3.15 wt. %S1 = 6.80 mg HC/g rock S2 = 19.50 mg HC/g rock Tmax = 447
A
Type III.
B
Woody plants of organic derived-input.
C
Lacustrine origin.
D
Immature source rock.
Explanation: 

Detailed explanation-1: -Source rocks are usually shales or limestones (sedimentary rocks). To be a productive source rock, the rock needs time to mature (time to form the oil and/or gas) and the hydrocarbons need to be able to migrate to a reservoir or seep.

Detailed explanation-2: -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.

Detailed explanation-3: -Source rock potential is evaluated based on three parameters (organic amount, organic type, and maturity). Analytical instruments, such as elemental analyzers, Rock-EvalĀ® instruments, and vitrinite reflectance microscopes, are used for analysis of outcrop samples, well cuttings, and cores.
