Equinor公司已在巴西大陆架的Raia项目下启动钻探作业。 该公司新闻处发布了这一消息。

作为钻井作业的一部分，计划在巴西海岸约200公里处、深度约2900米处钻探6口井。负责此次作业的钻井船“瓦拉里斯DS-17”号于2024年7月签订合同，并于3月24日开始作业。这是巴西正在开发的最重要的天然气项目之一，也是Equinor公司最大的海外投资项目，投资额约为90亿美元。

DS-17：

  • 是一艘超深水钻井船；
  • 设计 — GustoMSC P10000；
  • 由韩国现代重工建造；
  • 可容纳210人；
  • 能够在超过3600米的深度作业；
  • 自2023 年 9 月以来，该公司一直在巴西大陆架为Equinor进行作业。

“ Raia是Equinor目前正在开发的最大项目，也是我们投资组合中最深的作业。虽然钻井工作正在进行中，但FPSO的集成和调试工作也在积极推进，这将使我们能够在2028年安全地开始生产，” Equinor项目、钻井和采购执行副总裁G. Tungesvik表示。

拉亚计划

Raia项目位于坎波斯盆地，包括开发两个盐下气田——Raia Manta和Raia Pintada。天然气和凝析油的总可采储量超过10亿桶油当量。

项目合作伙伴：

  • Equinor （自2016 年起运营）— 35%；
  • 雷普索尔中石化巴西公司— 35%；
  • Petrobras — 30%。

Raia Manta 和 Raia Pintada 字段：

  • 位于BM-C-33区块（由雷普索尔中石化于2010 年发现）；
  • 2023年9月， Equinor向巴西国家石油管理局（ANP）提交了该区块内两个油田的商业性声明和开发计划；
  • 选定的开发方案包括使用一艘日产能为 12.6 万桶的FPSO；
  • 天然气出口能力——每天1600万立方米（约占巴西天然气总需求的15% ）；
  • Raia Manta和Raia Pintada的开发将是巴西第一个在海上处理天然气并直接连接到国家天然气输送系统而无需陆上处理的项目；
  • 预计该项目生命周期内的平均二氧化碳排放量低于每桶石油当量 6 公斤；

  1. 通过联合循环燃气轮机确保低碳排放强度；

  2. 这些是燃气和蒸汽联合循环机组，在运行过程中可显著减少碳排放；

  3. 燃气轮机与蒸汽轮机结合使用，可以利用原本会损失的多余热量。

Equinor Began Drilling Operations Under the Raia Project Offshore Brazil

— March 25, 2026

Equinor has started drilling operations under the Raia project on the continental shelf of Brazil.
This was reported by the company’s press service.

As part of the drilling campaign, 6 wells are planned to be drilled approximately 200 km off the coast of Brazil at a depth of about 2,900 m. The drilling vessel Valaris DS-17, contracted for this operation in July 2024, began work on March 24. This is one of the most significant gas projects under development in Brazil. It is also Equinor’s largest foreign investment — about 9 billion US dollars.

DS-17:

  • is an ultra-deepwater drilling vessel;
  • design — GustoMSC P10000;
  • built by the South Korean shipbuilding company Hyundai Heavy Industries;
  • accommodates 210 people;
  • capable of operating at depths of more than 3.6 thousand metres;
  • has been operating on the Brazilian continental shelf for Equinor since September 2023.

“Raia is Equinor’s largest project currently under development and the deepest-water operation in our portfolio. While drilling is ongoing, work is actively progressing on the integration and commissioning of the FPSO, which will allow us to safely start production in 2028,” said G. Tungesvik, Executive Vice President for Projects, Drilling and Procurement at Equinor.

Raia Project

Raia is located in the Campos Basin and involves the development of two pre-salt gas fields — Raia Manta and Raia Pintada. Total recoverable reserves of natural gas and gas condensate exceed 1 billion barrels of oil equivalent.

Project partners:

  • Equinor (operator since 2016) — 35%;
  • Repsol Sinopec Brasil — 35%;
  • Petrobras — 30%.

Raia Manta and Raia Pintada fields:

  • located in block BM-C-33 (discoveries were made by Repsol Sinopec in 2010);
  • a declaration of commerciality and development plans for the two fields within the block were submitted by Equinor to Brazil’s National Petroleum Agency (ANP) in September 2023;
  • the selected development concept includes the use of one FPSO with a capacity of 126 thousand barrels per day;
  • gas export capacity — 16 million cubic metres per day (about 15% of Brazil’s total gas demand);
  • the development of Raia Manta and Raia Pintada will be the first project in Brazil to process gas offshore and connect directly to the national gas transmission system without onshore processing;
  • the average CO₂ emissions over the project lifecycle are estimated to be less than 6 kg per barrel of oil equivalent;

  1. low carbon intensity will be ensured through combined-cycle gas turbines;

  2. these are combined gas and steam units, which significantly reduce carbon emissions during operation;

  3. the use of a gas turbine together with a steam turbine allows utilization of excess heat that would otherwise be lost.
