据世界能源12月22日消息：Rystad Energy的分析显示，如果12月剩余时间未能有任何重大油气发现，2021年全球油气发现量有望达到75年来的最低全年水平。截至11月底，今年全球已发现的总储量为47亿桶油当量，由于本月迄今没有宣布重大发现，石油行业正面临自1946年以来最严重的损失。这也意味着，与2020年发现的125亿桶油当量相比，产量将大幅下降。
液体仍然是碳氢化合物的主要成分，占总发现量的66%。2021年11月宣布了7项新发现，新发现储量约2.19亿桶油当量。今年的月平均探明产量为4.24亿桶。累积数量的减少突显出没有大的个体发现，就像往年一样。
“尽管一些排名靠前的勘探项目计划在今年年底前进行钻探，但即使是重大发现也可能无法为2021年的发现量做出贡献，因为这些井可能无法在本日历年完成。因此，2021年的累计发现量肯定会是几十年来的最低水平，”Rystad Energy上游研究副总裁Palzor Shenga说。
2021年11月发现的最大油田是俄罗斯卢克石油公司在墨西哥海岸附近发现的Yoti West油田，据估计该油田拥有约7500万桶油当量的可采资源。这一发现加强了卢克石油公司在北美国家的累计发现量。然而，这些数量仍然不足以进行商业开发，在制定开发概念之前，还需要进行类似规模的进一步发现。不过，这些发现确实给墨西哥带来了希望，即该国可以停止或减缓其产量下降。几口井计划在各个投标轮次提供的区块中钻探，其中许多井由领先的国际石油公司提供。
马来西亚近海，Nangka-1成为在SK 417区块内连续钻探的第二口勘探井。该井由泰国国家运营商PTTEP钻探至3758米深，并在中、晚中新世VI期碎屑岩储层中发现了低硫天然气。
挪威继续挖掘中小型油田，为利用现有基础设施实现这些发现提供了机会。

Global Oil And Gas Discoveries Set To Hit 75-Year Low In 2021
Global oil and gas discoveries in 2021 are on track to hit their lowest full-year level in 75 years should the remainder of December fail to yield any significant finds, Rystad Energy analysis shows. As of the end of November, total global discovered volumes this year are calculated at 4.7 billion barrels of oil equivalent (boe) and, with no major finds announced so far this month, the industry is on course for its worst discoveries toll since 1946. This would also represent a considerable drop from the 12.5 billion boe unearthed in 2020.
Liquids continue to dominate the hydrocarbon mix, making up 66% of total finds. Seven new discoveries were announced in November 2021, unearthing around 219 million boe of new volumes. The monthly average of discovered volumes this year now stands at 424 million boe. A reduction in cumulative volume highlights the absence of large individual finds, as has been the case in previous years.
“Although some of the highly ranked prospects are scheduled to be drilled before the end of the year, even a substantial discovery may not be able to contribute towards 2021 discovered volumes as these wells may not be completed in this calendar year. Therefore, the cumulative discovered volume for 2021 is on course to be its lowest in decades,” says Palzor Shenga, vice president of upstream research at Rystad Energy.
The largest discovery in November 2021 was Russian group Lukoil’s Yoti West off the coast of Mexico, which is estimated to hold around 75 million boe of recoverable resources. The discovery strengthens Lukoil’s cumulative discovered volumes in the North American nation. However, these volumes are still insufficient for commercial development and would require further discoveries of a comparable scale before a development concept could be drawn up. These discoveries do, however, give hope to Mexico that the country can halt or slow down its production decline. Several wells are scheduled to be drilled in blocks offered in various bid rounds, many by leading international oil companies.
Offshore Malaysia, Nangka-1 became the second successive exploration well drilled within Block SK 417. The wildcat was drilled by Thai state operator PTTEP to a depth of 3,758 meters and discovered sweet gas within the Middle to Late Miocene Cycle VI clastic reservoirs.
Norway continues to unearth small-to-medium finds, providing an opportunity to materialize these discoveries with available infrastructure.
