The S 2 peak represents the rate of hydrocarbon generation.
|
|
|
Kerogen containing high sulfur concentration.
|
|
|
Reliable indicator of maturity.
|
|
|
The temperature at which the maximum rate of hydrocarbon generation occurs in a kerogen sample during pyrolysis analysis.
|
Detailed explanation-1: -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-2: -Resulting changes in the burial temperatures and pressures lead to further changes in kerogen composition including loss of hydrogen, oxygen, nitrogen, sulfur, and their associated functional groups, and subsequent isomerization and aromatization Such changes are indicative of the thermal maturity state of kerogen.
Detailed explanation-3: -Coal as a Petroleum Source Rock and Reservoir Rock Coal is defined as a rock composed of more than 50% organic matter by weight and is thus by definition the rock type that is richest in organic matter.
