道达尔能源和中海油计划于 2025 年在乌干达艾伯特湖项目产出首批石油

对翠鸟和 Tilenga 上游项目以及东非原油管道和新炼油厂的投资将为该国带来 200 亿美元的经济促进。

乌干达有望在 2025 年前从其艾伯特湖开发项目产出第一批石油,目前为止,该项目已钻探了道达尔能源公司 Tilenga 一侧计划钻探的 426 口井中的 63 口,以及中国海洋石油总公司 Kingfisher 项目首批石油开采所需的 11 口井中的 9 口。

乌干达能源与矿产开发部长露丝·南卡比尔瓦·森塔穆 8 月 21 日在坎帕拉举行的新闻发布会上表示,道达尔能源在 Tilenga 的 63 口井超过了首次产油所需的数量。

道达尔能源勘探与生产乌干达公司、中海油乌干达有限公司和乌干达国家石油公司(UNOC)正在开发价值 60 亿美元的上游 Tilenga 和 Kingfisher 项目,这些项目加上东非原油管道(EACOP)(50 亿美元)和乌干达炼油厂项目(40 亿美元),将为乌干达经济带来约 200 亿美元的总投资。

Nankabirwa 在她的项目更新中指出

  • 随着 Tilenga 工业区 99.7% 的完工和中央处理设施 (CPF) 的持续建设按计划进行,土建工程预计将在产出第一批石油前全面投入运营。
  • 包括 Tilenga、Kingfisher 和 EACOP 在内的所有主要项目的土地收购已接近完成。
  • 乌干达公司获得了价值 20 亿美元的合同,显示出其强大的本地内容成分。

南卡比尔瓦对记者说:“我们的综合方针涵盖了上游、中游和下游部门,使乌干达能够为全球石油供应做出重大贡献,促进经济增长,增加国民收入”,同时保持经济增长、社会发展和环境保护之间的平衡。

部长指出,乌干达估计有 65 亿桶石油储量(其中 15 亿桶被视为可采储量)“不仅对乌干达经济至关重要,而且对全球能源市场也有重要影响”——为全球能源安全做出贡献。

为了增加这些储量,从而延长开发中游项目的寿命,2023 年 2 月和 5 月分别向 UNOC 和 DGR Energy Turaco Uganda SMC Ltd. 授予了 Kasuruban 和 Turaco 合同区域的勘探许可证。

正在进行更多探索

根据该部最新消息,Oranto Petroleum Ltd. 和 Armour Energy Uganda Ltd. 自 2017 年以来已持有 Ngassa Deep & Shallow Play 和 Kanywataba 合同区域的许可证,但仍在继续进行技术研究,尚未进行钻探。

乌干达是一个内陆国家,目前没有碳氢化合物生产。勘探和开发集中在阿尔伯特-爱德华裂谷盆地,该盆地是东非裂谷系统的一部分,位于乌干达西北部,延伸至刚果民主共和国。

中海油北京研究院于 2019 年 3 月在国际石油技术会议(IPTC)上发表的一篇论文中指出,勘探井稀缺,加上地震数据质量差,导致该地区储层潜力评估困难。

然而,自 2006 年以来,Tilenga 油田 1 号区块和 2 号区块以及 Kingfisher 油田 3A 区块已发现 15 亿桶可采储量。

在高峰期,上游合作伙伴——总能源公司(56.67%)、中海油(28.33%)和联合石油公司(15%)——预计全流域日产量为 230,000 桶,以满足国内需求并通过东非共同体石油管道出口到印度洋沿岸的坦桑尼亚坦噶港。

至于中下游组件,Nankabirwa 告诉记者:

  • 沃利公司东非管道项目工程设计、采购、施工管理和调试合同执行工作正在有序推进,主要营地和管场土建工程稳步推进,已向坦桑尼亚交付7批共计500公里管线管道。
  • 目前正与阿联酋的 Alpha MBM Investments LLC 就与乌干达炼油厂开发有关的重要商业协议进行谈判,该炼油厂将满足该国国内石油需求以及东非共同体的需求。
  • 联合石油公司正在采取措施确保国内供应,最近与维多巴林签署了供应协议,并从肯尼亚能源和石油监管局获得了石油许可证。

道达尔能源公司持有 EACOP 62% 的股份,其他股东包括联合国石油公司 (15%)、坦桑尼亚石油开发公司 (15%) 和中海油 (8%)。

TotalEnergies, CNOOC on Target for First Oil at Uganda’s Lake Albert Project in 2025

Investment in the Kingfisher and Tilenga upstream projects together with the East African Crude Oil Pipeline and a new refinery represents a $20-billion economic lift to the country.

Uganda is on track to deliver first oil from its Lake Albert development by 2025 after having so far drilled 63 of the 426 wells planned at TotalEnergie’s Tilenga side of the project and nine out of the 11 wells required for first oil at Chinese major CNOOC’s Kingfisher project.

TotalEnergies’ 63 wells at Tilenga exceed the number needed for first oil, Uganda’s Minister for Energy and Mineral Development, Ruth Nankabirwa Ssentamu, told a press briefing in Kampala on 21 August.

TotalEnergies E&P Uganda, CNOOC Uganda Ltd, and the Uganda National Oil Company (UNOC) are developing the $6-billion upstream Tilenga and Kingfisher projects which together with the East African Crude Oil Pipeline (EACOP) ($5 billion) and the Uganda Refinery project ($4 billion) represent a combined investment of approximately $20 billion into Uganda's economy.

In her project update Nankabirwa noted that

  • Civil works are expected to be fully operational in time for first oil with the Tilenga Industrial Area 99.7% complete and the ongoing construction of the Central Processing Facility (CPF) proceeding as planned.
  • Land acquisition is nearly complete for all major projects including Tilenga, Kingfisher, and the EACOP.
  • $2 billion worth of contracts have been awarded to Ugandan companies, showcasing a strong local content component.

“Our integrated approach, which includes the upstream, midstream, and downstream sectors, positions Uganda to significantly contribute to the global oil supply, fostering economic growth and boosting national revenue” while maintaining a balance between economic growth, social development and environmental conservation, Nankabirwa told reporters.

The minister noted that Uganda’s estimated 6.5 billion bbl of reserves (of which 1.5 billion bbl are deemed as recoverable) “are not only pivotal for Uganda's economy but also have significant implications for the global energy market … contributing to global energy security.”

To add to those reserves, thus extending the life of the development’s midstream projects, exploration licenses were granted in February and May 2023 to UNOC and DGR Energy Turaco Uganda SMC Ltd. for the Kasuruban and Turaco contract areas, respectively.

More Exploration in the Works

Oranto Petroleum Ltd. and Armour Energy Uganda Ltd. have held licenses since 2017 for the Ngassa Deep & Shallow Play and the Kanywataba contract areas but continue technical studies and have yet to drill, according to the ministry’s update.

Uganda is a landlocked country with no current hydrocarbon production. Exploration and development is centered in the Albert-Edward Rift Basin, a part of the East African Rift system which lies in northwest Uganda and extends into the Democratic Republic of Congo.

The scarcity of exploration wells, combined with poor-quality seismic data, has made it problematic to assess reservoir potential in the area, as described in a paper presented in March 2019 at the International Petroleum Technology Conference (IPTC) by CNOOC’s Research Institute in Beijing.

Since 2006, however, 1.5 billion bbl of recoverable reserves have been discovered in Blocks 1 and 2 of the Tilenga field and Block 3A of Kingfisher.

At peak plateau, upstream partners—TotalEnergies (56.67%), CNOOC (28.33%), and UNOC (15%)—expect to produce 230,000 B/D basinwide to satisfy domestic needs and for export via the EACOP to Tanzania’s port of Tanga on the Indian Ocean coast.

As for the midstream and downstream components, Nankabirwa told reporters:

  • Worley is progressing with its execution of the engineering, procurement, construction management, and commissioning contract related to the EACOP, with civil works at the main camps and pipe yards progressing steadily. Seven batches of line pipes, totaling 500 km, have been delivered to Tanzania.
  • Negotiations are ongoing with the UAE’s Alpha MBM Investments LLC for key commercial agreements related to the development of the Uganda refinery which will supply the country’s domestic petroleum needs as well as demand of the greater East African Community.
  • UNOC is taking steps to secure domestic supply having recently signed a supply agreement with Vitol Bahrain and obtained a petroleum license from the Energy and Petroleum Regulatory Authority in Kenya.

TotalEnergies holds a 62% share in EACOP with UNOC (15%), Tanzania Petroleum Development Corporation (15%), and CNOOC (8%).
