This paper reviews the theory, technologies, and practice of oilfield-geothermal co-development (OGC), a pathway to revitalize mature oilfields and supply low-carbon energy under China's dual-carbon goals. It presents development modes (waste-heat recovery, same-well co-production, enhanced heat extraction) and an integrated technical system spanning well conversion, reservoir stimulation, surface energy conversion, and intelligent lifecycle control. The Dongyi project in Shengli Oilfield serves as a field example, with challenges in high-temperature material reliability, multiphysics coupling, and coordination between geothermal and remaining oil recovery.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では油田開発の規模は限られるが、既存坑井・廃坑を活用した地熱開発や廃熱回収は、資源循環型の脱炭素技術として参考になる。特に、油ガス田インフラの転換ノウハウは、国内の地熱・温泉熱利用やCCS適地評価と親和性が高い。
In the global GX context
Globally, OGC aligns with the energy transition by repurposing hydrocarbon infrastructure for low-carbon heat, complementing geothermal and CCUS pathways. It offers a replicable model for mature basins in Asia and beyond, though disclosure frameworks (TCFD/ISSB) would need to account for such hybrid assets.

📄 Abstract（原文）
Abstract Driven by the global energy transition and China's dual-carbon goals, oil and gas field development faces challenges in achieving sustainable development. Oilfield-geothermal co-development (OGC) offers a pathway for revitalizing mature oilfields and supplying low-carbon energy. This article describes the resource endowment, genetic mechanisms, and oil-heat-water co-occurrence relationships of geothermal resources in oilfields, examines the theory and key technologies for OGC, and proposes an integrated technical system. Development modes include waste-heat recovery from produced fluids at central processing stations, integrated utilization of waste heat from high-temperature oil wells, same-well co-production of oil and geothermal resources, and same-layer enhanced fluid production and heat extraction. The technical system includes evaluation and conversion of existing oil and gas wells, reservoir stimulation and efficient heat extraction, surface energy conversion and integrated utilization, and life-cycle system integration with intelligent control. The Dongyi project in Shengli Oilfield illustrates field implementation of this framework. Current challenges include the long-term reliability of materials and equipment in high-temperature environments, accurate prediction and control of multiphysics coupling in complex reservoirs, and the potential interference and coordinated optimization between geothermal development and remaining oil and gas recovery. Future OGC development is expected to expand into deeper subsurface domains, integrate the development of oil and gas, geothermal energy, and associated mineral resources, and pursue breakthroughs in key technologies and critical equipment.
