Kinetics

Kinetic parameters that describe chemical reaction rates include the activation energy and frequency factor. Most petroleum system modeling assumes that oil and gas generation can be described by a series of parallel first-order kinetics, where the rate of each reaction depends on the concentration of only one reactant. Kinectic models in which the generation of different subcomponents of the kerogen are individually stimulated (i.e., each subcomponent has a different set of frequency factors and distribution of activation energies). These subcomponents can be defined by molecular weight range (e.g., C7-C15, C16-C25, C26-C35, C36-C45, C46-C55, C56-C80), compound type, or a combination thereof.[1]
