今年全球超过一半重大油气发现来自深水

    中国石化新闻网讯 据今日石油2019年12月8日报道，全球今年迄今重要的海上油气发现主要在俄罗斯、塞浦路斯、南非、马来西亚和圭亚那。最近的一份报告称，今年到目前为止，大多数重大油气发现都位于海上，其中超过一半的重大油气发现是深水发现。

    向深水和前沿地区的进军表明，今年许多大型能源公司的勘探策略发生了转变。根据估计的总储量(百万桶油当量)，前10大油气发现的运营商包括俄罗斯天然气工业股份公司(俄气)、美国埃克森美孚公司、法国道达尔公司、泰国PTTEP公司、意大利埃尼公司、英国图洛石油公司、荷兰皇家壳牌公司和中国海洋石油总公司。

    今年5月，俄气宣布该公司在喀拉海亚马尔半岛的大陆架上获得了两个重大天然气发现，分别是丁科夫发现和尼亚梅斯科耶发现。这两个发现分别位于俄气相邻的两个区块Rusanovsky区块和Nyarmeysky区块。这两个发现的天然气储量加起来超过15亿桶油当量，是今年全球迄今最大的天然气发现。

    今年2月，塞浦路斯Glaucus发现预示着埃克森美孚公司与卡塔尔石油公司合作运营的第10号海上区块拥有巨大的天然气储量。2月17日，Glaucus-1井在4200米深的水中开钻。合作伙伴初步估计天然气储量在5万亿到8万亿立方英尺之间。在此之前，意大利埃尼公司在去年在邻近的第6号区块获得了卡里普索发现。

    此外，道达尔公司今年2月在南非莫塞尔湾地区的深水海域获得了Brulpadda凝析油发现。根据目前对Brulpadda凝析油发现的估计，其总储量为5.58亿桶油当量，钻井作业将在2020年初开始。

    埃克森美孚公司还在圭亚那近海的斯塔布鲁克区块获得了一系列石油发现，包括Yellowtail、Tilapia和Tripletail。英国图洛石油公司在与斯塔布鲁克区块相邻的奥林杜伊克区块内获得了Joe和Jethro石油发现。

    全球船舶数据提供商和船舶估值服务商VesselsValue在报告中表示，今年全球其它重大发现包括马来西亚的Lang Lebah、英国的Glengorm、挪威的Froskelar和Frosk、美国的Blacktip、安哥拉的Agogo和埃及的Nour。

    Guyana discoveries among largest for 2019

    Major offshore discoveries this year include countries as diverse as Russia, Cyprus, South Africa, Malaysia and Guyana. The majority of major discoveries so far this year have been in the offshore sector with over half being deep-water finds, VesselsValue, an online valuation, AIS and market intelligence service for the maritime and offshore sectors, said in a recent report.

    This move into deeper water and frontier areas shows a shift in exploration tactics for many major energy companies this year. Operators of the top 10 discoveries, by estimated total reserves (MMBOE – Million Barrels of Oil Equivalent), include Gazprom, ExxonMobil, Total, PTTEP, Eni, Tullow, Shell and CNOOC.

    In May of this year Gazprom announced two major gas discoveries on the shelf of the Yamal Peninsula in the Kara Sea, Dinkov and Nyarmeyskoye. These two fields being situated in adjacent Gazprom operated blocks, Rusanovsky and Nyarmeysky respectively. The combined gas reserves of these two discoveries are thought to be in excess of 1.5 billion BOE making this the largest discovery of 2019.

    The Cypriot Glaucus discovery in February of this year heralded significant gas reserves in offshore block 10 operated by ExxonMobil in conjunction with Qatar Petroleum. The Glaucus-1 well was drilled on the 17th of February in 4200m of water. Preliminary estimates by the company put the reserves of natural gas to be between 5 to 8 trillion cubic feet (Tcf.). This follows on from the 2018 Calypso discovery by Italian major Eni in neighbouring block 6.

    Also, in February Total made the Brulpadda condensate discovery in the Mossel Bay area deep-water offshore South Africa. Current estimates for Brulpadda put total reserves at 558 MMBOE with drilling set to commence in early 2020.

    ExxonMobil also had a series of oil discoveries in the Stabroek block offshore Guyana including Yellowtail, Tilapia and Tripletail. Adjacent to the Stabroek block are the Tullow oil discoveries Joe and Jethro in the Orinduik block.

    VesselsValue said other major discoveries this year included Lang Lebah (Malaysia), Glengorm (United Kingdom), Froskelar and Frosk (Norway), Blacktip (USA), Agogo (Angola) and Nour (Egypt).
