位于澳大利亚西北部大陆架帝汶海的巴罗莎天然气项目目前已完成70.6%。 Santos公司于2024年4月18日在其2024年第一季度报告中宣布了这一点。

桑托斯论文：

  • 浮式生产储卸油 (FPSO) 设施和达尔文液化天然气综合设施之间 262 公里长的出口天然气管道的安装将于下周完成；
  • 海底脐带缆、立管和出油管 (SURF) 活动已完成；
  • 生产钻探仍在继续：6 口井中的第 2 口已接近完成；
  • 16 个上部模块中的 13 个已安装在 FPSO BW Opal 上，并计划于第一季度离开新加坡 Seatrium 造船厂前往现场。 2025；
  • 生产运营环境计划的磋商正在进行中，预计将于今年下半年向监管机构 NOPSEMA 提交；
  • 达尔文液化天然气延长寿命项目已完成 39%。

巴罗莎天然气项目

它涉及开发巴罗莎凝析气田（GCF），为达尔文液化天然气厂供应液化天然气。 凝析气田位于达里夫纳西北近海约 285 公里处。 生产的天然气必须通过巴罗莎和达尔文管道运输到现有的 DLNG 设施。 该项目基础设施包括：FPSO BW Opal（从 BW Offshore 租用 15 年，可选择将租约再延长 10 年）、一个海底生产综合体 (SPC) 和 2 条天然气管道。

巴罗莎出口天然气管道

它的总长度为262公里，直径为26英寸。 天然气管道由碳钢制成，外部防腐和混凝土涂层，敷设深度为34至254 m。 它将把巴罗莎油田连接到备用达尔文管道。 该管道的建设原定于 10 月开始，并于 2024 年 4 月完工，但该项目多次面临当地的不满和诉讼。

阿拉斯加北坡的皮卡油田进展如何？

Santos表示，该公司在实施价值26亿美元的Pikka项目方面取得了重大进展：

  • 截至2024年3月31日，项目已完成47%；
  • 第一季度 完成了7口井的钻井工作；
  • 管道垂直支架安装工作完成65%以上，冬季管道铺设完成61%以上；
  • 截至本季度末，海水处理厂建设已完成62%。

皮卡存款：

  • 位于阿拉斯加北坡自治市以西；
  • 项目第一阶段： 获得所有主要环境和监管批准， 包括1个井场，但后续阶段预计将再增加2个井场，并将产量提高到最多16万桶/天；
  • 在油田开发第一阶段的框架内，石油产量预计为每天8万桶；
  • 皮卡油田的石油将通过半岛上现有的基础设施进行运输，包括库帕鲁克管道和跨阿拉斯加管道系统（TAPS）。

Santos董事总经理兼首席执行官K. Gallagher表示，Barossa和Pikka是世界级项目，对Santos至关重要，并将至少在未来10至15年为公司提供长期稳定的现金流。 Barossa 项目预计将在第三季度产出第一批天然气。 2025年，Pikka准备在2026年开始生产。

Barossa Gas Project on Australia’s Continental Shelf Nears Completion

— April 24, 2024
2 0 0

The Barossa gas project, located in the Timor Sea on the continental shelf of north-west Australia, is now 70.6% complete. The Santos company announced this on April 18, 2024 in its report for the 1st quarter of 2024.

Santos theses:

  • installation of the 262km export gas pipeline between the floating production, storage and offloading (FPSO) facility and the Darwin LNG complex is due to be completed next week;
  • subsea umbilicals, risers and flowlines (SURF) campaign completed;
  • production drilling continues: 2nd of 6 wells is close to completion;
  • 13 of the 16 topside modules have already been installed on the FPSO BW Opal and are scheduled to leave the Seatrium shipyard in Singapore for the field in Q1. 2025;
  • consultations are ongoing on the environmental plan for production operations, the submission of which to the regulator NOPSEMA is expected in the 2nd half of the year;
  • Darwin LNG life extension project is 39% complete.

Barossa Gas Project

It involves the development of the Barossa gas condensate field (GCF) to supply the Darwin LNG liquefied natural gas plant. The gas condensate field is located approximately 285 km offshore northwest of Darivna. Produced natural gas must be transported via the Barossa and Darwin pipelines to existing DLNG facilities. The project infrastructure includes: FPSO BW Opal, chartered from BW Offshore for 15 years with the option to extend the lease for another 10 years, a subsea production complex (SPC) and 2 gas pipelines.

Barossa Export Gas Pipeline

Its total length is 262 km and its diameter is 26 inches. The gas pipeline, made of carbon steel with an external anti-corrosion and concrete coating, will be laid at a depth of 34 to 254 m. It will connect the Barossa field to the backup Darwin pipeline. Construction of the pipeline was supposed to begin in October and be completed in April 2024, but the project has repeatedly faced local discontent and litigation.

How are things going with the Pikka field on the North Slope of Alaska?

According to Santos, the company has made significant progress in implementing the $2.6 billion Pikka project:

  • as of March 31, 2024, the project is 47% complete;
  • for the 1st quarter drilling work was completed at 7 wells;
  • work on installing vertical pipeline supports was completed by more than 65%, and pipeline laying in winter was completed by more than 61%;
  • as of the end of the quarter, construction of the seawater treatment plant was 62% complete.

Pikka deposit:

  • located in Alaska west of the North Slope Borough;
  • 1st phase of the project: received all major environmental and regulatory approvals, includes 1 well pad, but subsequent phases are expected to add 2 more well pads and increase production to a maximum of 160 thousand barrels per day;
  • within the framework of the 1st phase of field development, oil production is expected to be 80 thousand barrels per day;
  • oil from the Pikka field will be transported through existing infrastructure on the peninsula, including the Kuparuk Pipeline and the Trans-Alaska Pipeline System (TAPS).

According to Santos managing director and chief executive K. Gallagher, Barossa and Pikka are world-class projects that will be critical to Santos and will provide the company with long-term and stable cash flows for at least the next 10 to 15 years. First gas from the Barossa project is expected in Q3. 2025, and Pikka is preparing to start production in 2026.
