据Oil & Gas Journal网站3月5日消息 Petro Rio SA同意收购道达尔勘探与生产do Brasil Ltda坎波斯盆地BM-C-30勘探区块（Wahoo）28.6%的权益。
Wahoo位于弗雷德油田以北30-35公里处，海拔1400米，盐前碳酸盐岩储层位于5000-7000米处。2008年的石油发现和2010年进行的地层测试显示，产量潜力超过1.4亿桶。根据试井的地层测试，平均初始产能估计为每口井1万桶/日以上，总产量超过4万桶/日。
Wahoo项目包括四口生产井和两口注水井的钻井，并在油井和弗雷德FPSO之间进行回接，回接的预计资本支出为3亿美元，钻井为3.6亿美元，海底设备为1亿美元，FPSO和其他项目的调整为4000万美元。
此次收购，连同2020年11月与英国石油公司签署的协议，将使PetroRio的经营权益达到64.3%，但这两项交易都要经过监管部门的批准和满足常规的条件。

Petro Rio to acquire Wahoo interest from Total
Petro Rio SA agreed to acquire Total E&P do Brasil Ltda.’s 28.6% interest in exploration block BM-C-30 (Wahoo) in Campos basin, offshore Brazil.
Wahoo lies 30-35 km north of Frade field in 1,400 m of water with a carbonate reservoir in the presalt at 5,000-7,000 m. Oil discoveries in 2008 and formation tests carried out in 2010 have shown production potential of over 140 million bbl. Average initial productivity is estimated at over 10,000 b/d per well and total production exceeding 40,000 b/d, based on the formation test made in the pilot well.
The Wahoo base project covers drilling of four producer wells and two injector wells with tieback between the wells and the Frade FPSO with an expected capex of $300 million for the tieback, $360 million for well drilling, $100 million for subsea equipment, and $40 million for adjustments to the FPSO and other items.
The acquisition, together with a November 2020 deal signed with BP, will bring PetroRio’s operated interest to 64.3% (OGJ Online, Nov. 19, 2020). Both deals are subject to regulatory approvals and usual conditions.
