据今日石油网2022年4月9日报道，咨询公司韦斯特伍德全球能源集团说，荷兰皇家壳牌公司和法国道达尔能源公司日前在纳米比亚海上获得了两项突破性的发现，这意味着这是一个类似于圭亚那-苏里南盆地的远景区。
2月4日，壳牌公司在位于2913A区块的格拉夫-1井获得了第一个轻质石油突破性发现。
韦斯特伍德全球能源集团表示：“有未经证实的报告称，发现井在钻进过程中钻遇了大约60米厚的含油气层，潜在商业资源约为3亿桶油当量。”
壳牌公司正在钻探另一口井La Rona井，这显然是对首次发现的井进行评价，以确认其商业开发的潜力。韦斯特伍德全球能源集团表示，有传言称格拉夫-1井可能拥有10亿桶石油和5万亿-6万亿立方英尺天然气储量。
道达尔能源公司在壳牌公司发现格拉夫-1井20天以后在位于2913B区块的维纳斯远景构造上获得了第二个突破性发现。维纳斯1-X井在高品质的下白垩纪储层中钻遇了大约84米厚的纯产油层。韦斯特伍德全球能源集团说，有传言称维纳斯1-X井发现了数十亿桶的石油储量，但官方尚未公布具体数字。
能源市场情报平台表示，这些突破性发现证明了存在一个广泛、丰富的油灶，分析表明“下白垩纪维纳斯远景区的潜在范围高达5.8万平方公里，与苏里南-圭亚那的上白垩纪相差无几”。
该公司表示，纳米比亚存在苏里南-圭亚那规模的含油区“当然是可能的”，“前提是存在圈闭，深水油藏分布广泛，足够好的品质”。
韦斯特伍德全球能源集团指出，“这些突破性发现对纳米比亚来说是一个期待已久的突破，对橙色盆地延伸到的南非来说也可能是一个突破”。
这也类似于圭亚那-苏里南盆地的发现，圭亚那的发现为苏里南创造了兴奋。
在圭亚那海上，埃克森美孚公司迄今已经获得了25个发现，总油气储量超过100亿桶油当量。 道达尔能源公司和阿帕奇公司也在苏里南近海获得了令人兴奋的发现。圭亚那-苏里南盆地如今是地球上最令人兴奋的新兴石油省，到2035年前，圭亚那近海石油产量将使其成为世界上人均石油产量最高的国家。
韦斯特伍德全球能源集团认为，与圭亚那的丽莎大油田类似，纳米比亚的格拉夫井和维纳斯井的发现和开发之间可能需要5年时间，前提是能够确定产量，并克服一些技术难题。
“有一件事是肯定的——全球的一个新的油气勘探热点已经在纳米比亚出现” ，韦斯特伍德全球能源集团如是说。

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.
