如果克服挑战,液化天然气将成为东非的可能性

法律、安全和基础设施方面的障碍阻碍了东非近海的石油和天然气进展。

在东非,石油和天然气的大部分故事都围绕着液化天然气。 

伍德麦肯兹的两位分析师表示,即便如此,该地区的液化天然气仍面临许多挑战,寻求石油和天然气项目的运营商必须克服法律障碍、安全问题和基础设施的整体缺乏。

运营商在莫桑比克和坦桑尼亚都发现了天然气。

伍德麦肯兹撒哈拉以南非洲上游石油和天然气高级研究分析师利亚姆·耶茨表示,坦桑尼亚的财政条件此前不利于发展,但政府现在似乎更加支持该行业。

“我们认识到,如果不按条款行事,这些天然气将继续滞留,”耶茨说。“政府首脑在重新谈判条款以使项目得以继续进行方面取得了进展。”

Equinor 则对其坦桑尼亚天然气项目进行了减记。

耶茨指出,莫桑比克拥有大量天然气,但液化天然气项目面临各种挑战。由于莫桑比克北部的安全局势,TotalEnergies 于 2021 年 4 月宣布其运营的莫桑比克液化天然气项目遭遇不可抗力。

“情况已经有所改善,但道达尔不会回来,除非他们确信他们不必放下工具,”耶茨说。

他表示,由于该项目至少要推迟两年,如果 TotalEnergies 确实恢复运营,那么直到本世纪下半叶才可能实现首个液化天然气项目。

埃尼公司运营的 Coral South 项目使用莫桑比克近海 Coral Sul 浮式液化天然气 (FLNG) 工厂,该项目仍在继续推进。

该项目于 2017 年由埃尼集团代表合作伙伴埃克森美孚、中石油、GALP、KOGAS 和 ENH 批准作为运营商,并于 6 月首次向该工厂引入天然气,预计今年晚些时候将首批液化天然气装运。该超深水项目使莫桑比克跻身液化天然气生产国之列。

Coral Sul FLNG长432 m,宽66米,重约22万吨,其生活区模块最多可容纳350人。该设施位于水深约 2,000 米处,由 20 条缆绳系泊。Coral Sul FLNG拥有每年340万吨的天然气液化能力,将从位于鲁伍马盆地近海的Coral储层生产450 Bcm的天然气。Coral-Sul FLNG 是第一个部署在非洲大陆近海深水区的 FLNG 设施。

“我们听到的最新消息是埃尼公司可能倾向于建造第二个 FLNG [设施],”耶茨说。 

但耶茨表示,在莫桑比克北部,埃尼公司在肯尼亚拥有一个“看似”有希望的勘探井,但没有达到预期。 

“我实际上并不期望在不久的将来肯尼亚近海出现太多,”他说。

在陆上,塔洛据称正在南洛基查盆地开发一个项目。

“这种油是蜡质的、重的,不容易生产。它需要一条加热的管道才能进入市场,”耶茨说。

伍德麦肯兹的撒哈拉以南非洲上游研究总监盖尔·安德森表示,海盗活动曾经是非洲东海岸的一个主要问题,但现在似乎已经减少,尽管这在西非仍然是一个问题。大约五年前,从索马里到莫桑比克,海盗活动很普遍,有一些引人注目的事件被报道,但“这种情况似乎已经消失了,”她说。

安德森说:“海上项目在非洲有很多优势,”因为它消除了与陆上项目相关的某些风险。

其中之一是基础设施,这是交通所必需的。 

例如,虽然各国热衷于从石油和天然气中获得收入,但诸如 TotalEnergies 支持的乌干达管道项目等管道却吸引了“环保人士的极大兴趣”,安德森说。

耶茨表示,TotalEnergies 面临着很大的压力,涉及管道建设以及因此而流离失所的人们将如何得到补偿。

他补充说,随着对该项目的审查,一些银行表示他们不会为这个 70 亿美元的项目提供资助。 

耶茨说,“我们遇到了一些挑战”,但也得到了政府的支持。“这是一场有趣的战斗。”

LNG an East Africa Possibility If Challenges Are Overcome

Legal, security and infrastructure hurdles stall oil and gas progress offshore East Africa.

In East Africa, much of the oil and gas story revolves around LNG. 

Even so, a host of challenges surround LNG in the region, and operators seeking oil and gas projects have to overcome legal obstacles, security issues and an overall lack of infrastructure, according to a pair of analysts at Wood Mackenzie.

Operators have found gas in both Mozambique and Tanzania.

Tanzania’s fiscal terms were previously unfavorable to development, but the government now seems to be more supportive of the industry, Liam Yates, Wood Mackenzie’s senior research analyst for Sub Saharan Africa Upstream Oil & Gas, said.

“It recognizes that if it doesn’t move on the terms, this gas will remain stranded,” Yates said. “There has been progress toward heads of government to renegotiate the terms to enable the project to go ahead.”

For its part, Equinor took a write-down on its gas project in Tanzania.

Mozambique has lots of gas, Yates noted, but there are various challenges regarding LNG projects. TotalEnergies declared force majeure on its operated Mozambique LNG project in April 2021 due to a security situation in the north part of the country.

“It has improved, but Total will not return until it is sure they won’t have to put down their tools,” Yates said.

With what is looking like at least a two-year delay on the project, first LNG is unlikely until the second half of the decade, if TotalEnergies does return, he said.

The Eni-operated Coral South project using the Coral Sul Floating Liquefied Natural Gas (FLNG) plant offshore Mozambique continues moving forward.

The project, sanctioned in 2017 by Eni as the operator on behalf of partners Exxon Mobil, CNPC, GALP, KOGAS and ENH, had gas first introduced to the plant in June with first LNG cargo expected later this year. The ultra-deepwater project adds Mozambique to the list of LNG-producing countries.

The Coral Sul FLNG is 432 m long and 66 meters wide, weighs around 220,000 tons and can accommodate up to 350 people in its living quarter module. The facility is located in about 2,000 m water depth and is moored by 20 lines. Coral Sul FLNG has a gas liquefaction capacity of 3.4 million tons per year and will put in production 450 Bcm of gas from the Coral reservoir, located in the offshore Rovuma Basin. Coral-Sul FLNG is the first FLNG facility deployed in deepwater offshore the African continent.

“The latest talk we’ve been hearing is that Eni is potentially favoring a second FLNG [facility],” Yates said. 

But north of Mozambique, Eni had a “vaguely” promising exploration well in Kenya that didn’t live up to expectations, Yates said. 

“I realistically don’t expect much offshore Kenya in the near future,” he said.

Onshore, Tullow is purportedly looking to farm down a project in the South Lokichar Basin.

“The oil is waxy, heavy, not the easiest to produce. It needs a heated pipeline to get to market,” Yates said.

Gail Anderson, Wood Mackenzie’s research director for Sub-Saharan Africa Upstream, said that piracy, once a major concern off the eastern coast of Africa, seems to have diminished, although it is still an issue in West Africa. About five years ago, piracy was common from Somalia down to Mozambique, with some high-profile incidents being reported, but that “seems to have kind of fallen away,” she said.

“Being offshore has a lot of advantages in Africa,” Anderson said, because it negates certain risks associated with onshore projects.

One of those concerns is around infrastructure, which is necessary for transport. 

For instance, while countries are keen to obtain revenue from oil and gas, pipelines such as the TotalEnergies-backed Uganda pipeline project attract “an awful lot of interest from environmentalists,” Anderson said.

There has been a lot of pressure on TotalEnergies, Yates said, regarding the pipeline and how people displaced by it will be compensated.

And with the scrutiny on the project, some banks have said they will not help finance the $7 billion project, he added. 

“It’s got a few challenges” but government support as well, Yates said. “It’s an interesting battle.”
