伍德麦肯齐:阿拉斯加国家石油储备的Willow项目获得美国内政部批准

美国内政部已批准阿拉斯加国家石油储备区 (NPR-A) 的 Willow 项目。该决定是开发三个平台,而不是最初寻求的五个钻探场地,同时康菲石油公司放弃了 68,000 英亩的现有租约。新的决定记录取代了 2020 年 10 月收到的决定记录,该记录后来因法庭案件而被腾空。伍德麦肯兹的分析师表示,三垫的批准仍将使该项目在经济上可行。

Wood Mackenzie 美洲(非 L48)上游业务负责人 Mark Oberstoetter 表示:“这一决定将使康菲石油公司能够推进开发工作,目前正在等待公司的最终投资决定。” “康菲石油公司拥有庞大的全球项目库存。Willow 的增长为二叠纪加权投资组合增加了一些所需的多样性,但该公司也始终阐明其严格的投资标准和供应成本框架。康菲石油公司经常表示,任何低于三个井场的“替代 E”项目范围的项目都会导致 Willow 项目不经济。我们的独立经济模型证实了这一说法。”

根据 Wood Mackenzie 的模型,将允许的井数从 3 个井场减少到 2 个将使该项目的税后内部收益率从 15% 降低到 9.8%,并降低总税后现值( 10%贴现率)从18.65亿美元降至负5400万美元。这些估计使用 60 美元/桶布伦特原油长期基本情况价格。阿拉斯加的开发成本、运输关税和政府特许权使用费/石油税高于美国其他产油地区。

Oberstoetter 表示:“我们计算出该项目 30 年生命周期中政府的收入份额总计为 152 亿美元(按 10% 折算到 2023 年,现值为 47 亿美元)。” “这些收入将使阿拉斯加州、联邦政府或原住民团体受益,他们将分享收益。美国联邦政府的特许权使用费目前用于资助受欢迎的国家公园计划。如今,这些特许权使用费大部分来自墨西哥湾的海上项目,这是一个成熟的碳氢化合物地区,大规模的商业发现较少。”

“根据阿拉斯加州众议院和阿拉斯加州参议院的决议,三垫项目范围得到了阿拉斯加立法机构的一致支持。拟议的 Willow 范围得到了许多(但不是全部)原住民团体和领导人的支持。奥伯斯托特说,在任何地方,任何项目都能得到一致支持是很少见的。

Oberstoetter 补充道:“这一决定对于阿拉斯加上游行业来说是一个里程碑,该行业在过去十年中从 Nanushuk 油田勘探中取得了成功,但迄今为止,将这些发现转化为开发的进展缓慢。其中许多项目都位于国家管理的土地上,不需要联邦政府批准。北坡生产正在恢复。随着 Willow 加入 Pikka 等其他项目、Milne Point、Narwhal、Nuna 和 Coyote 的新油田,我们预计到 2030 年产量将恢复到 70 万桶/日,上次达到 2008 年的水平。如果没有 Willow 和这些其他新项目的生产,Trans Alaska管道系统最终会遇到低流量问题,危及来自北坡的所有生产。”

Wood Mackenzie 的预测表明,Willow 的范围 1 和范围 2 排放强度将低于其他阿拉斯加项目,也低于当前许多美国石油进口来源。范围 3 排放,即原油衍生产品的燃烧和使用,将是最大的排放源。但这对于所有其他项目来说同样如此。拜登政府还寻求将波弗特海联邦水域从未来的租赁中删除。

Wood Mackenzie: Willow project in National Petroleum Reserve-Alaska receives approval from US Interior Department

Published by , Deputy Editor
Oilfield Technology,


The US Interior Department has approved the Willow project in the National Petroleum Reserve-Alaska (NPR-A). The decision is for a three-pad development instead of the originally sought five drill sites and is coupled with ConocoPhillips relinquishing 68 000 acres of existing leases. The new Record of Decision replaces one received in October 2020, which was later vacated following a court case. The three-pad approval will still render the project economically viable, say analysts at Wood Mackenzie.

“The decision will allow ConocoPhillips to progress the development, which now just awaits corporate final investment decision,” said Mark Oberstoetter, head of Americas (non-L48) upstream for Wood Mackenzie. “ConocoPhillips has a large and global project inventory. Growth at Willow adds some desired diversity to a Permian-weighted portfolio, but the company has also consistently articulated its rigorous investment criteria and cost-of-supply framework. ConocoPhillips has frequently said that anything less than the “Alternative E” project scope for three well pads would render the Willow project uneconomic. Our independent economic model substantiates that claim.”

According to Wood Mackenzie’s model, reducing the number of allowed wells from three-well pads to two would have changed the project’s post-tax internal rate of return from 15% to 9.8% and drop total post-tax present value (10% discount rate) from US$1865 million to negative US$54 million. Those estimates use a US$60/bbl Brent long-term base case price. Development costs, transport tariffs and the government royalties/petroleum taxes are higher in Alaska than other US oil-producing regions.

“Our calculation of the government share of revenue over the 30-year life of the project totals US$15.2 billion (US$4.7 billion present value discounted to 2023 at 10%),” said Oberstoetter. “That revenue will benefit the state of Alaska, the Federal government or Indigenous groups set to share in the proceeds. Royalties to the US Federal government are currently used to fund the popular National Parks programme. Most of those royalties today are sourced from offshore projects in the Gulf of Mexico, a maturing hydrocarbon region with fewer large-scale, commercial discoveries.”

“The three-pad project scope had unanimous Alaskan legislative support following a resolution from both the Alaska House and the Alaska Senate. The proposed Willow scope was supported by many, but not all, Indigenous groups and leaders. It is rare for any project anywhere to have unanimous support,” said Oberstoetter.

Oberstoetter added: “The decision is a milestone for Alaska’s upstream sector, which has had exploration success from the Nanushuk play in the past decade but has, so far, been slow to move those discoveries to development. Many of those projects are on state-administered lands, not requiring federal approval. A revival of North Slope production is now on. With Willow joining other projects like Pikka, new pads at Milne Point, Narwhal, Nuna and Coyote, we see production returning to 700 000 bpd by 2030, levels last seen in 2008. Without production from Willow and these other new projects, the Trans Alaska Pipeline System would eventually run into low flow issues, jeopardising all production coming from the North Slope.”

Wood Mackenzie’s projections suggest Willow’s Scope 1 and 2 emissions intensity would be lower than other Alaska projects, and lower than many of the current sources of US oil imports. Scope 3 emissions, the burning and use of the products derived from crude oil, would be the largest source of emissions. But that is equally true for all other projects. The Biden Administration is also looking to remove the federal waters of the Beaufort Sea from future leasing.
