Hydrocarbon discoveries in the Western Black Sea have proved the presence of both thermogenic and biogenic petroleum systems. The presence of Tertiary biomarkers in oils from the Romanian part of the Western Black Sea sub‐basin, and correlation with Oligocene to Lower Miocene black shales, suggests that the thermogenic petroleum system is sourced mainly by the Oligocene – Miocene Maikop Group. Older source rocks may also be present locally in other parts of the sub‐basin, but their contribution is currently poorly understood.

渐新世-中新世麦考普烃源岩在罗马尼亚近海和西黑海的3D盆地建模

在西部黑海发现的碳氢化合物已证明同时存在热成因和生物成因的石油系统。西部黑海子盆地罗马尼亚部分的石油中存在第三纪生物标志物，并且与渐新世至下中新世黑色页岩相关，这表明热成因石油系统主要来自渐新世-中新世迈科普集团。在该次盆地的其他地方也可能存在较老的烃源岩，但目前对它们的贡献了解甚少。
