据油田技术9月3日报道，埃尼集团通过其子公司NAOC在尼日尔三角洲OML61地区的Obiafu-Obrikom油田的深层序列中发现了大量天然气和凝析油。
Obiafu-41探井总深度达4374米，在渐新世三角洲层序中遇到了一个重要的天然气和凝析油气藏，含有130多米优质含烃砂层。在较深的钻井层序中，发现了约1万亿立方英尺的天然气和6000万桶伴生凝析油。储量潜力还待发掘，将在下一次评估活动中进行评估。
该井可输送超过1亿立方英尺/天的天然气和3000桶/天的凝析油，并可立即投产，以提高NAOC的天然气产量。
这一发现是NAOC合资公司计划的钻井活动的一部分，旨在探索油田和深层油藏的机会，把握立即进入市场的契机。

Eni makes gas and condensates discovery onshore Niger Delta
Eni, through its affiliate NAOC (Eni 20%, operator, NNPC 60%, Oando 20%) has made a significant gas and condensate find in the deeper sequences of the Obiafu-Obrikom fields, in OML61, onshore Niger Delta.
The Obiafu-41 Deep well has reached a total depth of 4,374 m encountering an important gas and condensate accumulation within the deltaic sequence of Oligocene age comprising more than 130 m of high quality hydrocarbon-bearing sands. The find amounts to approximately 1 trillion ft3 of gas and 60 million bbl of associated condensate in the deep drilled sequences. The discovery has further potential that will be assessed with the next appraisal campaign.
The well can deliver in excess of 100 million ft3/d of gas and 3000 bpd of associated condensates, and will be immediately put onstream to increase NAOC’s gas production.
The discovery is part of a drilling campaign planned by NAOC JV and aimed at exploring near-field and deep pool opportunities as immediate time to market opportunities.
