据今日石油网2021年9月6日报道，习惯上，分析师们通常根据概括性或宽泛的假设来评估石油资源。 然而，全球著名咨询集团伍德麦肯兹（Wood Mackenzie/WM）表示，在试图了解从哪里获得更多石油时，精确度则是关键。
全球上游行业仍然异常活跃，到2040年前必须满足4500亿桶当量的未开发供应需求。 WM表示，目前全球总体上不存在资源短缺，但供应机会被掩盖，因为该行业的供应远远大于需求。 这意味着只有最好的石油——最得天独厚的资源——才能进入市场。
在WM的分析中，了解哪些属性影响采收率有助于回答他们提出的问题：‘哪些国家拥有最受推崇的深水石油资源? ’
WMa地下研究副总裁安德鲁·莱瑟姆博士说：“我们发现全球80%剩余深水石油资源将来自5个国家，这5个国家分别是巴西、美国、圭亚那、尼日利亚和安哥拉，因此，了解储油层的质量是识别哪国的石油是最好石油的关键。
圭亚那斯塔布鲁克区块的深水石油资源迄今已经发现了超过90亿桶的石油，其质量是世界上最好的，这个区块预计将提供高产量。
美国赫斯公司首席执行官John Hess表示：“圭亚那油藏是世界上质量最好的油藏之一，具有高孔隙度和高渗透率，有望带来很高的采收率和产量。”
随着圭亚那海上的每一次新发现，分析师们都在提高对产量的预测，表明这个新的产油国有望成为拉丁美洲最大的产油国之一，可能仅次于巴西。
赫斯说：“这是世界上主要的产油区之一。我们在那里看到数十亿桶石油的勘探潜力。”

80% of remaining deepwater oil resources in the world will come from just five countries – WoodMac
Traditionally, analysts often assess oil resources based align="justify"> The upstream industry remains active and must fill the 450 billion barrels equivalent (boe) of undeveloped supply needed by 2040. Today, there is no resource shortage overall, but the supply opportunity is overshadowed because the industry has a lot more supply than demand, WoodMac said. This means align="justify"> In the case of WoodMac’s analysis, understanding what attributes impact oil recovery factors helped answer their pointed question, ‘Which countries have the best performing deepwater reservoirs?’
“We found that 80% of the remaining deepwater oil resources will come from five countries (Brazil, US, Guyana, Nigeria, and Angola), therefore, understanding the quality of their reservoirs is key to identifying who has the best oil,” said Dr. Andrew Latham, Vice-President Subsurface Research for Wood Mackenzie.
The deepwater reservoirs in Guyana’s Stabroek block where more than 9 billion barrels of oil have been found rank among the best in the world for quality and are expected to deliver high productivity.
“The reservoirs rank among the highest quality in the world with high porosity and permeability that are expected to deliver very high recovery factors and production rates,” says John Hess, CEO of Hess Corporation.
With every new discovery off the coast of Guyana, analysts have been ramping up their projections for output, making it clear that the new oil producing nation is align="justify"> “It’s one of the major petroleum provinces in the world,” Hess said. “We see multi-billion barrels of exploration potential there.”
