继 2023 年野火之后,加拿大石油和天然气井附近的阴燃威胁着生产

罗伯特·塔特尔,彭博社 2024 年 4 月 15 日

(彭博社)“去年加拿大创纪录的野火季节留下的大火可能会导致该国近 3% 的天然气产量减少。

根据彭博社分析的政府数据,共有 50 起所谓的“姆比”火灾仍在雪层下闷烧,位于油气井和其他生产设施附近。这些地点每天生产的天然气相当于加拿大能源中心阿尔伯塔省约 80,000 桶石油,此外还生产近 14,000 桶/天的原油。

面临中断风险最大的公司包括该国最大的天然气钻探公司电气石石油公司(Tourmaline Oil Corp.),以及油砂巨头Cenovus Energy Inc.和派拉蒙资源有限公司(Paramount Resources Ltd.)。规模较小的运营商也可能受到影响,包括少数人持股的Westbrick Energy Ltd.。

去年,炎热、干燥的天气导致了该国有史以来最严重的野火季节,纽约和其他美国城市的天空变得漆黑。 3 月底,加拿大超过 65% 的地区出现异常干旱或干旱,该国正准备迎接另一个充满烟雾的夏季。

根据政府预测,加拿大今年可能面临另一个灾难性的火灾季节,因为危险的干燥条件加上厄尔尼诺天气模式导致的高于正常温度。艾伯塔省于2月20日宣布今年山火季节开始,这是近年来最早的一次。随着整个春季气温的升高,僵尸火灾以及新的火灾可能会爆发。

剩下的火会燃烧成地球上的有机物,包括泥炭,这些泥炭很容易闷烧,很难扑灭。艾伯塔省野火局发言人乔西·圣-翁格(Josee St-Onge)在电话中表示,2023年发生的火灾一般不会像新出现的火灾那样构成威胁,但今年大量的遗留火灾是一个问题。

“好处是我们了解它们,而且我们已经为此工作了一年,”她说,并警告说,该省正在进入火灾爆发的时期。

Cenovus 的一位代表表示,该公司正在借鉴去年的经验,为本季的野火做好准备,包括更新火灾计划和完成风险评估,以确保识别和缓解植被过剩的地区。托玛琳和派拉蒙的发言人没有立即回应置评请求。

韦斯特布里克去年关闭了多达 30,000 桶油当量,剩余的火灾并不是“非常担心”的理由,首席执行官肯·麦卡格蒂 (Ken McCagherty) 在电话中表示。他说,去年引发野火的大部分植被已经被烧毁。

“今年的情况比去年好得多,”麦卡格蒂说。

去年,雪佛龙公司(Chevron Corp.)、加拿大自然资源有限公司(Canadian Natural Resources Ltd.)和Baytex Energy Corp.有时关闭了相当于约30万桶/日的产量,因为大火侵蚀了油井和加工基础设施,主要集中在不列颠哥伦比亚省和加拿大西部的页岩油气产区。艾伯塔省边境。大火烧毁了该国约 4% 的森林。

与 2016 年的火灾季节相比,这种损失相形见绌,当时一场毁灭性的大火导致超过 1 MMbpd 的生产被关闭,麦克默里堡 (Fort McMurray) 的部分地区被夷为平地,麦克默里堡是靠近大多数生产商油砂作业的最大城市,并造成约保险损失达 37 亿美元,使其成为加拿大损失最惨重的自然灾害。

“Zombie fires” smoldering near Canadian oil and gas wells threaten production following 2023 wildfires

Robert Tuttle, Bloomberg April 15, 2024

(Bloomberg) – Leftover blazes from last year’s record wildfire season in Canada are threatening to knock out almost 3% of the country’s natural gas production.

A total of 50 so-called “zombie” fires still smoldering beneath layers of snow are located near oil and gas wells and other production facilities, according to government data analyzed by Bloomberg News. Those sites yield natural gas equivalent to about 80,000 bpd of oil in Canada’s energy heartland of Alberta alone, in addition to almost 14,000 bpd of crude.

Companies most at risk of disruptions include Tourmaline Oil Corp., the country’s biggest gas driller, as well as oil-sands giant Cenovus Energy Inc. and Paramount Resources Ltd. Smaller operators could also be affected, including closely held Westbrick Energy Ltd.

Hot, dry weather contributed to the country’s worst-ever wildfire season last year, darkening skies over New York and other U.S. cities. And with over 65% of Canada abnormally parched or in drought at the end of March, the nation is bracing for another smoke-filled summer.

Canada could be facing another catastrophic fire season this year as dangerously dry conditions combine with higher-than-normal temperatures buoyed by the El Niño weather pattern, according to a government forecast. Alberta declared the start of its wildfire season this year on Feb. 20, the earliest in recent years. Zombie fires, along with new ones, could flare up as temperatures rise throughout the spring.

The leftover fires burn into organic matter in the earth including into peat, which smolders easily and is difficult to extinguish. The blazes from 2023 aren’t generally as much of a threat as new conflagrations that emerge, but the large number of carryover fires this year is a problem, Alberta Wildfire spokeswoman Josee St-Onge said by phone.

“The advantage is we know them, and we have been working on them for a year,’’ she said, cautioning that the province is entering a period when blazes flare up.

A representative for Cenovus said the company is building on what it learned last year to prepare for wildfires this season, including updating its fire program and completing risk assessments to ensure areas with excess vegetation are identified and mitigated. Spokespeople for Tourmaline and Paramount didn’t immediately respond to requests for comment.

Westbrick, which shut in as much as 30,000 boe last year, the leftover fires are not a reason to be “overly concerned,” Chief Executive Officer Ken McCagherty said by phone. Much of the vegetation that fueled last year’s wildfires has been burned off, he said.

“We’re in a far, far better position this year than last year,” McCagherty said.

Chevron Corp., Canadian Natural Resources Ltd. and Baytex Energy Corp. at times shut production equivalent to about 300,000 bopd combined last year as blazes encroached on wells and processing infrastructure, mostly in the western shale oil and gas producing regions along the British Columbia and Alberta border. The fires scorched about 4% of the country’s forests.

That damage was dwarfed by the fire season of 2016, when more than 1 MMbpd of production was shut during a devastating blaze that razed sections of Fort McMurray — the largest city near most producers’ oil-sands operations — and caused about C$3.7 billion in insured losses, making it Canada’s costliest natural disaster.
