New Insight into the Kinetics of Deep Liquid Hydrocarbon Cracking and Its Significance

Figure 6

Gas generation model for the cracking of residual oil in Type-II source rocks and expelled crude oil in reservoir under geological conditions (heating rate: 2°C/Ma). The conversion of the generation and cracking of oil and gas were obtained by kinetic extrapolation based on their kinetic parameters, wherein the kinetic parameters ( and ) applied in this model for oil generation were 51.4 kcal/mol and  s⁻¹ [9], for oil cracking in reservoir were 59.8 kcal/mol and  s⁻¹ [2], and for residual oil cracking in source were 56.1 kcal/mol and  s⁻¹ [61].
