European Unconventional Oil and Gas Assessment (EUOGA)

Within the European wide EUOGA project 82 hydrocarbon bearing shale formations within 21 countries were assessed for their unconventional resource potential. A stochastic volumetric assessment could be carried out for 49 formations, 15 of which are concluded to hold both shale gas and shale oil, 26 only gas and 8 only oil. The total resource estimation for all assessed shale formations in all countries combined amounts to 89.23 tcm of gas and 31.4 billion barrels of oil in place.在全欧范围的EUOGA项目框架下，研究人员对21个国家内的82套含烃页岩地层开展了非常规油气资源潜力评价。其中49套地层完成了随机容积评估，经评估，15套兼具页岩气（shale gas）与页岩油（shale oil）资源，26套仅含页岩气，8套仅含页岩油。本次对所有参与评估国家的全部页岩地层的总资源估算结果为：天然气储量89.23万亿立方米（tcm），原地原油储量314亿桶。
