據(jù)哈特能源7月6日消息，意大利埃尼集團(tuán)7月6日表示，該公司可能在加納近海的Eban勘探遠(yuǎn)景區(qū)發(fā)現(xiàn)了多達(dá)7億桶石油當(dāng)量。
埃尼公司在一份新聞稿中表示，Eban-1X井位于Sankofa中心西北約8公里處Eban-Akoma綜合設(shè)施CTP 4區(qū)塊，在Cenomanian期厚砂巖儲層中發(fā)現(xiàn)了一個80米的輕油柱。該井由Saipem 10000鉆井船鉆探，在3949米深的地方發(fā)現(xiàn)了碳?xì)浠衔铩Ｔ摼顬?45米，實測總深度為4170米。
埃尼表示，該發(fā)現(xiàn)使Sankofa油田和Eban-Akoma綜合設(shè)施之間的油氣儲量估計超過11億桶油當(dāng)量。上行可以通過評估鉆井來確認(rèn)。
埃尼在新聞稿中稱:“我們對大量3D地震數(shù)據(jù)集和井?dāng)?shù)據(jù)采集進(jìn)行了綜合分析，包括壓力測量、流體采樣和智能地層測試，并采用了最先進(jìn)的技術(shù)，對新發(fā)現(xiàn)進(jìn)行了評估。獲得的壓力和流體數(shù)據(jù)(油密度和氣油比)和儲層性質(zhì)與之前發(fā)現(xiàn)的Akoma和附近的Sankofa油田一致。”
根據(jù)生產(chǎn)測試數(shù)據(jù)，產(chǎn)能潛力估計為5000桶/天。
埃尼表示，鑒于該發(fā)現(xiàn)位于John Agyekum Kufuor浮式生產(chǎn)儲油輪(FPSO)和現(xiàn)有基礎(chǔ)設(shè)施附近，該發(fā)現(xiàn)可以通過連接FPSO快速進(jìn)入生產(chǎn)。
埃尼表示:“Eban油田的發(fā)現(xiàn)證明了埃尼在全球范圍內(nèi)實施的以基礎(chǔ)設(shè)施為主導(dǎo)的勘探戰(zhàn)略取得了成功。”
Eban是CTP 4區(qū)塊鉆的第二口井，緊隨Akoma天然氣和凝析油發(fā)現(xiàn)之后。
埃尼集團(tuán)持有該區(qū)塊42.469%的股權(quán)，是該區(qū)塊的運(yùn)營商。合作伙伴包括維多集團(tuán)(33.975%)、加納國家石油公司(10%)、Woodfields Upstream(9.556%)、GNPC Explorco(4%)。

Eni Makes ‘Significant’ Oil Discovery Offshore Ghana
Italy’s Eni said July 6 it has potentially discovered up to 700 million barrels of oil equivalent in place at the Eban exploration prospect offshore Ghana.
Located in CTP Block 4 in the Eban-Akoma complex about 8 km northwest of the Sankofa Hub, the Eban-1X well proved a single 80-m light oil column in a thick sandstone reservoir interval of Cenomanian age, Eni said in a press release. The well, drilled by the Saipem 10000 drillship, hit hydrocarbons at 3,949 m depth. The well reached a total measured depth of 4,170 m in a water depth of 545 m.
Eni said the discovery brings the estimated hydrocarbon in place between the Sankofa field and the Eban-Akoma complex to more than 1.1 Bboe. Upside could be confirmed with appraisal drilling.
“The new discovery has been assessed following comprehensive analysis of extensive 3D seismic datasets and well data acquisition including pressure measurements, fluid sampling and intelligent formation testing with state-of-the-art technology,” Eni said in the release. “The acquired pressure and fluid data (oil density and Gas-to-Oil Ratio) and reservoir properties are consistent with the previous discovery of Akoma and nearby Sankofa field.”
Deliverability potential is estimated at 5,000 bbl/d based on production testing data.
Given the discovery’s location near the John Agyekum Kufuor FPSO and existing infrastructure, Eni said the discovery can be fast-tracked to production with a subsea tie-in the FPSO.
“The Eban discovery is a testimony to the success of the infrastructure-led exploration strategy that Eni is carrying out in its core assets worldwide,” the company said.
Eban is the second well drilled in CTP Block 4 and follows the Akoma gas and condensate discovery.
Holding a 42.469% stake in the block, Eni serves as operator. Partners are Vitol (33.975%), Ghana National Petroleum Corp. (10%), Woodfields Upstream (9.556%), GNPC Explorco (4%).
