完整的论文全面概述和分析了 20 个全球案例研究，其中废弃的油井被改造用于地热应用，随后介绍了重要的井下和地面参数。从废弃和未激活的油井生产地热能具有良好的潜力。
在改造地热项目中，井底温度通常远低于传统地热井。鉴于这些项目气温较低，各方面都应做到优化。
虽然整篇论文详细介绍了作者在 20 个案例研究中研究的概念的效果，但本概要主要提供了这些概念的更高层次的总结，而不是对案例研究本身的讨论。
整篇论文中提到的所有案例研究，除了一个之外，都是模拟作品。完整论文的表 1 列出了一般信息，包括这些案例研究的区域位置和调查人员，而完整论文的表 2 提供了有关所提供案例的全面设计和生产信息。

The complete paper presents a comprehensive overview and analysis of 20 global case studies in which abandoned petroleum wells were retrofit for geothermal applications, followed by important downhole and surface parameters. Good potential exists for producing geothermal energy from abandoned and nonactivated petroleum wells.
In retrofitted geothermal projects, the bottomhole temperatures are usually much lower than conventional geothermal wells. Given the low temperatures of these projects, optimization should be achieved in all respects.
While the complete paper details the effect of the concepts investigated by the authors in the 20 case studies, this synopsis mainly offers a higher-level summary of these concepts rather than a discussion of the case studies themselves.
All case studies mentioned in the complete paper are simulation works except for one. Table 1 of the complete paper lists general information including the regional locations and investigators of these case studies, while Table 2 of the complete paper provides comprehensive design and production information about the cases provided.
