Identification of petroleum migration routes and reservoir filling processes is feasible by applying carbazoles or xanthones as molecular migration tracers. To verify their utility, a well-constrained migration route was chosen for this study: the petroleum migration along the Veslefrikk and Oseberg East fields until reaching the Statfjord Formation compartment within the Brage field in the Norwegian North Sea. This migration route comprises an ideal test case because the oil is sourced from the same kitchen area, yielding very similar oil families in all three fields, and because the maturity remains within the main oil window, below 0.9 Ro % vitrinite reflectance equivalence.

苯并咪唑和甲基氧杂蒽酮分子迁移示踪剂揭示了挪威北海 Veslefrikk、Oseberg-East 和 Brage 储层的迁移路线和填充历史


通过使用咔唑或氧杂蒽酮作为分子迁移示踪剂，可以确定石油迁移路线和储层填充过程。为了验证它们的效用，本研究选择了一条约束良好的迁移路线：沿着 Veslefrikk 和 Oseberg East 油田的石油迁移，直到到达挪威北海 Brage 油田内的 Statfjord Formation 隔间。这条迁移路线包括一个理想的测试案例，因为油来自同一个厨房区域，在所有三个油田中产生非常相似的油族，并且因为成熟度保持在主油窗内，低于 0.9 Ro % 镜质体反射当量。
