エクアドルの成熟油田における10年間の実装事例。坑井制御方法の再設計と、チュービング健全性試験での淡水を産出水に置換する2施策を導入。2016〜2025年に984件超の修井作業で安全性と生産性を維持しつつ、水輸送・廃棄に伴うCO2を約1,371トン削減した。既存作業の小幅な改変が運用脱炭素化の実践的経路となり得ることを示す。
English
A decade-long field implementation in a mature Ecuadorian oilfield. Two initiatives—redesigned well-control methodology and replacing freshwater with produced water for tubing integrity testing—were applied across 984+ workover operations (2016–2025) while maintaining safety and production. Reduced water transport and disposal cut associated CO2 emissions by ~1,371 tons, showing targeted modifications to conventional practices can deliver practical operational decarbonization.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本企業にとっては、海外資産でのScope1排出削減と水資源管理を両立させる運用改善の一事例として参考になる。SSBJ開示で求められるScope1削減施策の実務的裏付けとして、現場レベルでの定量的効果の示し方に示唆がある。
In the global GX context
Adds a rare field-scale, decade-long empirical case to the operational decarbonization literature, showing how water-management redesign in upstream oil and gas can deliver measurable Scope 1 reductions. Relevant to transition-plan credibility under ISSB/CSRD, where companies must evidence operational levers rather than rely on offsets.

📄 Abstract（原文）
Abstract Workover operations in mature oilfields require significant volumes of freshwater for well control and tubing integrity testing, generating considerable environmental impact through water sourcing, transportation, and disposal activities. In environmentally sensitive regions, these practices contribute directly to operational carbon footprint and create additional logistical challenges. This paper presents a decade-long field implementation of an innovative water management strategy developed for a mature Ecuadorian oilfield characterized by depleted reservoirs and an extensive well intervention program. The proposed approach focused on two key initiatives: redesigning the well-control methodology to significantly reduce fluid control requirements and replacing freshwater used during tubing integrity testing with produced water available within the field. A structured implementation process was developed, including engineering validation, operational risk assessment, field pilots, and standardization across the asset. Between 2016 and 2025, the methodology was applied in more than 984 workover operations while maintaining operational safety, well integrity, and production objectives. Additionally, reductions in water transportation and disposal requirements decreased associated CO2 emissions by approximately 1,371 tons. This is equivalent to the estimated emissions from approximately 7 one-way long-haul commercial flights between Houston and London, based on typical aircraft fuel consumption and standard aviation fuel CO2 emission factors. The results demonstrate that targeted modifications to conventional workover practices can provide a practical pathway toward operational decarbonization while preserving operational efficiency and enhancing oil productivity.
