法国超级能源公司 TotalEnergies 本周宣布,已开始在乌干达 Tilenga 开发项目进行商业钻探作业。

这个耗资100亿美元的大型项目预计将于2025年首次投产,峰值产量将达到19万桶/日。该项目的合作伙伴包括TotalEnergies(56.67%)、中海油(28.33%)和乌干达国家石油公司(15%)。

Tilenga 的开发计划于去年获得批准,涉及开发 6 个油田,共 31 个不同井场的 420 口井。据乌干达石油管理局称,目前至少有一个钻井平台正在运行,预计还有两个钻井平台将于今年晚些时候开始钻探。

该项目部分位于国家公园内,面对环境问题,TotalEnergies 计划使用埋地出油管线,100% 回注油田产出水,并承诺实现零常规火炬燃烧。这家超级巨头表示,将利用现场天然气来满足该项目的电力需求,同时提供剩余电力来支持管道运营和国家电网。

2022年2月,SLB获得TotalEnergies的一份定向钻井、完井和人工举升服务大合同。中国石油化工集团公司去年还获得了一份单独的合同,负责建造该项目的石油和天然气输送系统。中国中石化是该项目的钻井平台承包商。

Tilenga 开发项目是乌干达更广阔的阿尔伯特湖项目的两个项目之一。第二个是由中海油运营的 Kingfisher 项目,于 1 月份开始钻探作业。Kingfisher 计划要求从三个油田打 31 口井,预计峰值产能为 40,000 B/D。

艾伯特湖项目的累计高原产量为 23 万桶/天,将得到东非石油管道 (EACOP) 的支持,该管道将向邻国坦桑尼亚的港口城市坦噶输送大部分新供应。这条全长1443公里的跨境管道预计需要投资35亿美元,将成为世界上最长的加热管道,这是高效运输乌干达含蜡油所必需的。

除了 EACOP 之外,乌干达还寻求确保其作为新兴石油生产国的地位,拥有一座日产量 6 万桶的炼油厂,其产量是该国日消耗量的两倍多。政府正在寻求融资来支持炼油厂的建设,预计耗资约为 40 亿美元。

乌干达于 2006 年发现了石油储量,但由于缺乏法律框架和基础设施,将这些资源商业化的尝试长期受阻。该国的储量估计为 65 亿桶,其中可采储量为 14 亿桶。

Drilling

TotalEnergies Spuds First of Hundreds of Wells in Uganda Megaproject

Uganda is on course to become the newest African oil exporter by 2025.

French supermajor TotalEnergies announced this week that it has begun commercial drilling operations at the Tilenga development in Uganda.

The $10-billion megaproject is expected to reach first production by 2025 and achieve a peak output of 190,000 B/D. The project’s partners are TotalEnergies (56.67%), CNOOC (28.33%), and the Uganda National Oil Company (15%).

Sanctioned last year, the development plans for Tilenga involve tapping into six fields with a total of 420 wells from 31 different well pads. At least one rig is currently operating while two more are expected to begin drilling later this year, according to the Petroleum Authority of Uganda.

In the face of environmental concerns over the project, part of which falls inside a national park, TotalEnergies plans to use buried flowlines, reinject 100% of the fields’ produced water, and has committed to zero routine flaring. The supermajor said it will use the field gas to support the project's electric needs while delivering any surplus power to support pipeline operations and the national grid.

In February 2022, SLB was awarded a large contract for directional drilling, completions, and artificial lift services by TotalEnergies. The China Petroleum Chemical Corp. was also awarded a separate contract last year to build the project’s oil and gas transmission systems. China's SINOPEC is the project's rig contractor.

The Tilenga development is one of two projects that form the wider Lake Albert project in Uganda. The second is the Kingfisher project which is operated by CNOOC and began drilling operations in January. Plans for Kingfisher call for 31 wells from three pads that are expected to peak at 40,000 B/D.

With a cumulative plateau production of 230,000 B/D, the Lake Albert projects are to be supported by the East African Oil Pipeline (EACOP) that will deliver much of the new supply to the port city of Tanga in neighboring Tanzania. The 1443-km-long cross-border pipeline is expected to require an investment of $3.5 billion and will be the world’s longest heated pipeline, a feature required to efficiently transport Uganda’s waxy oil.

In addition to the EACOP, Uganda is seeking to secure its place as a rising oil producer with a 60,000-B/D refinery—a volume more than twice the country’s daily consumption. The government is seeking financing to support the building of the refinery which it estimates will cost around $4 billion.

Oil reserves were discovered in Uganda in 2006 but attempts to commercialize the resources were long stymied due to a lack of a legal framework and infrastructure. The country’s reserves are estimated to be 6.5 billion bbl with 1.4 billion bbl considered recoverable.
