據(jù)今日石油網(wǎng)2022年4月9日?qǐng)?bào)道，咨詢公司韋斯特伍德全球能源集團(tuán)說(shuō)，荷蘭皇家殼牌公司和法國(guó)道達(dá)爾能源公司日前在納米比亞海上獲得了兩項(xiàng)突破性的發(fā)現(xiàn)，這意味著這是一個(gè)類似于圭亞那-蘇里南盆地的遠(yuǎn)景區(qū)。

2月4日，殼牌公司在位于2913A區(qū)塊的格拉夫-1井獲得了第一個(gè)輕質(zhì)石油突破性發(fā)現(xiàn)。

韋斯特伍德全球能源集團(tuán)表示：“有未經(jīng)證實(shí)的報(bào)告稱，發(fā)現(xiàn)井在鉆進(jìn)過(guò)程中鉆遇了大約60米厚的含油氣層，潛在商業(yè)資源約為3億桶油當(dāng)量。”

殼牌公司正在鉆探另一口井La Rona井，這顯然是對(duì)首次發(fā)現(xiàn)的井進(jìn)行評(píng)價(jià)，以確認(rèn)其商業(yè)開(kāi)發(fā)的潛力。韋斯特伍德全球能源集團(tuán)表示，有傳言稱格拉夫-1井可能擁有10億桶石油和5萬(wàn)億-6萬(wàn)億立方英尺天然氣儲(chǔ)量。

道達(dá)爾能源公司在殼牌公司發(fā)現(xiàn)格拉夫-1井20天以后在位于2913B區(qū)塊的維納斯遠(yuǎn)景構(gòu)造上獲得了第二個(gè)突破性發(fā)現(xiàn)。維納斯1-X井在高品質(zhì)的下白堊紀(jì)儲(chǔ)層中鉆遇了大約84米厚的純產(chǎn)油層。韋斯特伍德全球能源集團(tuán)說(shuō)，有傳言稱維納斯1-X井發(fā)現(xiàn)了數(shù)十億桶的石油儲(chǔ)量，但官方尚未公布具體數(shù)字。

能源市場(chǎng)情報(bào)平臺(tái)表示，這些突破性發(fā)現(xiàn)證明了存在一個(gè)廣泛、豐富的油灶，分析表明“下白堊紀(jì)維納斯遠(yuǎn)景區(qū)的潛在范圍高達(dá)5.8萬(wàn)平方公里，與蘇里南-圭亞那的上白堊紀(jì)相差無(wú)幾”。

該公司表示，納米比亞存在蘇里南-圭亞那規(guī)模的含油區(qū)“當(dāng)然是可能的”，“前提是存在圈閉，深水油藏分布廣泛，足夠好的品質(zhì)”。

韋斯特伍德全球能源集團(tuán)指出，“這些突破性發(fā)現(xiàn)對(duì)納米比亞來(lái)說(shuō)是一個(gè)期待已久的突破，對(duì)橙色盆地延伸到的南非來(lái)說(shuō)也可能是一個(gè)突破”。

這也類似于圭亞那-蘇里南盆地的發(fā)現(xiàn)，圭亞那的發(fā)現(xiàn)為蘇里南創(chuàng)造了興奮。

在圭亞那海上，埃克森美孚公司迄今已經(jīng)獲得了25個(gè)發(fā)現(xiàn)，總油氣儲(chǔ)量超過(guò)100億桶油當(dāng)量。 道達(dá)爾能源公司和阿帕奇公司也在蘇里南近海獲得了令人興奮的發(fā)現(xiàn)。圭亞那-蘇里南盆地如今是地球上最令人興奮的新興石油省，到2035年前，圭亞那近海石油產(chǎn)量將使其成為世界上人均石油產(chǎn)量最高的國(guó)家。

韋斯特伍德全球能源集團(tuán)認(rèn)為，與圭亞那的麗莎大油田類似，納米比亞的格拉夫井和維納斯井的發(fā)現(xiàn)和開(kāi)發(fā)之間可能需要5年時(shí)間，前提是能夠確定產(chǎn)量，并克服一些技術(shù)難題。  

“有一件事是肯定的——全球的一個(gè)新的油氣勘探熱點(diǎn)已經(jīng)在納米比亞出現(xiàn)” ，韋斯特伍德全球能源集團(tuán)如是說(shuō)。

Breakthrough discoveries off Namibia coast mirror Guyana basin oil play – Westwood

Royal Dutch Shell and TotalEnergies have made two breakthrough discoveries offshore Namibia, which suggest a play like the Guyana-Suriname basin, according to Westwood Global Energy Group.

On February 4, Shell made the first one, a light oil discovery, in Block 2913A at the Graff-1 well.

“There are unconfirmed reports of a ~60m hydrocarbon bearing interval and a potential commercial resource of ~300mmboe,” Westwood said.

Shell is drilling another well, La Rona, in an apparent appraisal of the first find to confirm the potential for a commercial development. Westwood reported rumours which suggest Graff-1 could have 1 billion barrels of oil and 5-6 Tcf of gas.

The second discovery, by TotalEnergies, was made 20 days after Graff-1, at the Venus prospect in Block 2913B. The Venus 1-X well encountered approximately 84m of net oil pay in a good quality Lower Cretaceous reservoir. Westwood said there are rumours of a multi-billion barrel discovery, though no figures have been officially reported.

The energy market intelligence platform said the discoveries have proved the presence of an extensive, prolific oil kitchen, and that its analysis suggests that “the Lower Cretaceous Venus play has a potential extent of up to ~58,000km2, comparable to that of the Upper Cretaceous of Suriname-Guyana.”

It said a Suriname-Guyana scale oil province is “certainly possible”, “provided that the traps are present and the deepwater reservoirs are widespread and of good enough quality.”

The discoveries are a long-awaited breakthrough for Namibia, and potentially also for South Africa into which the Orange Basin extends, Westwood pointed out.

This is also similar to how discoveries played out in the Guyana-Suriname basin, with Guyana’s discoveries creating excitement for Suriname.

Offshore Guyana, ExxonMobil has made over 25 discoveries amounting to more than 10 billion oil-equivalent barrels. TotalEnergies and Apache have also made exciting finds offshore Suriname. The basin is the most exciting emerging oil province on the planet, with production offshore Guyana set to make it the highest per capita oil producer in the world by 2035.

Westwood sees a 5-year timeline between discovery and development as being possible for the Graff and Venus wells, similar to Guyana’s Liza field, if the volumes can be confirmed and some technical challenges are overcome.

“One thing is for certain – a new exploration hotspot has emerged.” Westwood said.
