Early development of the Bakken Petroleum System recognized the significance of source rock maturation and the onset of oil generation in determining the geographic limits of production. The process of oil generation kinetics within source rocks involves intricate chemical reactions, where the nature of organic matter and thermal history influence the production of petroleum products. While simple models work well for some kerogen types (Type I), they fail for others (Type II and III), revealing the limitations of assuming invariant kinetic properties. This study explores the complexity of oil generation kinetics and its significance, particularly in the context of the Bakken Formation. Various methods have been used to identify the boundaries of oil sources, yet many are inductive. This research introduces a novel method to distinguish between catagenesis and diagenesis in Bakken's organic matter.

A common linear relationship between activation energy (Ea) and frequency factor (ln(A)) appears in kinetic studies of source rocks, often attributed to statistical errors. This study investigates these relationships, revealing non-statistical compensation effects. Furthermore, extended kinetic models uncover a range of behaviors, highlighting the complexity of oil generation pathways. Notably, a kinetic compensation effect (KCE) is observed in the Bakken Formation, closely resembling findings for Type II kerogen. These compensation effects are not statistically forced, emphasizing their physiochemical origins. This research sheds light on the diverse KCEs within the Bakken Formation through a combination of experimental maturation, core analyses, and kinetic modeling. The study suggests that provenance, particularly for Type II kerogen, plays a crucial role in these effects. The data reveal multiple KCE patterns, including linear, inclined arch, and random clusters, with some transitioning between patterns during the oil generation process. These findings underscore the complexity of oil generation kinetics and its dependency on organic provenance. They also provide valuable insights for understanding oil reservoirs in the Bakken Formation and beyond.

巴肯石油系统的早期开发认识到烃源岩成熟度和石油生成的开始在确定生产地理限制方面的重要性。烃源岩内的生油动力学过程涉及复杂的化学反应，其中有机质的性质和热历史影响石油产品的生产。虽然简单模型适用于某些干酪根类型（I 型），但对于其他干酪根类型（II 型和 III 型）则不然，这揭示了假设不变动力学性质的局限性。这项研究探讨了生油动力学的复杂性及其意义，特别是在巴肯地层的背景下。人们已经使用了多种方法来确定石油来源的边界，但许多方法都是归纳法。这项研究介绍了一种区分巴肯有机质中的还原作用和成岩作用的新方法。

在烃源岩动力学研究中，活化能 (Ea) 和频率因子 (ln(A)) 之间存在常见的线性关系，通常归因于统计误差。本研究调查了这些关系，揭示了非统计补偿效应。此外，扩展的动力学模型揭示了一系列行为，凸显了石油生成途径的复杂性。值得注意的是，在 Bakken 地层中观察到了动力学补偿效应 (KCE)，与 II 型干酪根的发现非常相似。这些补偿效应并非统计上强制的，而是强调其物理化学起源。这项研究通过实验成熟度、岩心分析和动力学模型的结合，揭示了巴肯地层内的各种 KCE。研究表明，来源，尤其是 II 型干酪根，在这些影响中发挥着至关重要的作用。数据揭示了多种 KCE 模式，包括线性、倾斜拱形和随机簇，以及在石油生成过程中模式之间的一些转变。这些发现强调了石油生成动力学的复杂性及其对有机来源的依赖性。它们还为了解巴肯地层及其他地区的油藏提供了宝贵的见解。
