據世界能源12月22日消息：Rystad Energy的分析顯示，如果12月剩余時間未能有任何重大油氣發現，2021年全球油氣發現量有望達到75年來的最低全年水平。截至11月底，今年全球已發現的總儲量為47億桶油當量，由于本月迄今沒有宣布重大發現，石油行業正面臨自1946年以來最嚴重的損失。這也意味著，與2020年發現的125億桶油當量相比，產量將大幅下降。

液體仍然是碳氫化合物的主要成分，占總發現量的66%。2021年11月宣布了7項新發現，新發現儲量約2.19億桶油當量。今年的月平均探明產量為4.24億桶。累積數量的減少突顯出沒有大的個體發現，就像往年一樣。

“盡管一些排名靠前的勘探項目計劃在今年年底前進行鉆探，但即使是重大發現也可能無法為2021年的發現量做出貢獻，因為這些井可能無法在本日歷年完成。因此，2021年的累計發現量肯定會是幾十年來的最低水平，”Rystad Energy上游研究副總裁Palzor Shenga說。

2021年11月發現的最大油田是俄羅斯盧克石油公司在墨西哥海岸附近發現的Yoti West油田，據估計該油田擁有約7500萬桶油當量的可采資源。這一發現加強了盧克石油公司在北美國家的累計發現量。然而，這些數量仍然不足以進行商業開發，在制定開發概念之前，還需要進行類似規模的進一步發現。不過，這些發現確實給墨西哥帶來了希望，即該國可以停止或減緩其產量下降。幾口井計劃在各個投標輪次提供的區塊中鉆探，其中許多井由領先的國際石油公司提供。

馬來西亞近海，Nangka-1成為在SK 417區塊內連續鉆探的第二口勘探井。該井由泰國國家運營商PTTEP鉆探至3758米深，并在中、晚中新世VI期碎屑巖儲層中發現了低硫天然氣。

挪威繼續挖掘中小型油田，為利用現有基礎設施實現這些發現提供了機會。

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.
