This paper presents the development of a tool to perform risk assessment for deep geothermal projects. The tool is aimed at project developers to help them present their project to local authority, decision-makers and financers so they can highlight how they take into account risks and consider mitigation measures to minimize them. The main criteria for this tool are the simplicity of use, the quality of presentation and flexibility. It is based on results from the H2020 GEORISK project that identified risks that apply to geothermal projects and proposed insurance schemes all over Europe. A characteristic of this tool is that it considers all the categories of risks that a project may face, including geological, technical, environmental risks as well as risks related to the social, economic and political contexts. The tool can be customized: selection of risks in a list that can be completed, adaptable rating scheme for risk analysis, possibility to choose the best display for results depending on the user needs. Two case applications are presented, one in the Paris Basin considering a doublet targeting the Upper Trias, a geological layer that presents some technical challenges; and one in the Upper Rhine graben targeting a fault zone, where the risk of induced seismicity must be carefully considered. A posteriori risk assessment highlights the main issues with these types of projects, and the comparison between the two cases emphasizes the flexibility of the tool, as well as, the different ways to present the results depending on the objective of the analyses.

深层地热项目风险评估工具的开发:巴黎盆地和上莱茵河地堑的应用实例

本文介绍了对深层地热项目进行风险评估的工具的开发。该工具旨在帮助项目开发商向地方当局、决策者和财务人员介绍他们的项目,以便他们可以强调他们如何考虑风险并考虑缓解措施以将风险降至最低。该工具的主要标准是使用简单、演示质量和灵活性。它基于 H2020 GEORISK 项目的结果,该项目确定了适用于地热项目的风险,并提出了整个欧洲的保险计划。该工具的一个特点是它考虑了项目可能面临的所有风险类别,包括地质、技术、环境风险以及与社会、经济和政治背景相关的风险。该工具可以定制:在可以完成的列表中选择风险,用于风险分析的适应性评级方案,根据用户需要选择最佳结果显示的可能性。介绍了两个案例应用,一个在巴黎盆地,考虑针对 Upper Trias 的双峰,这是一个存在一些技术挑战的地质层;一个位于上莱茵河地堑,目标是断层带,必须仔细考虑诱发地震的风险。后验风险评估突出了这些类型项目的主要问题,两种案例之间的比较强调了工具的灵活性,以及​​根据分析目标呈现结果的不同方式。根据用户需要选择最佳结果显示的可能性。介绍了两个案例应用,一个在巴黎盆地,考虑针对 Upper Trias 的双峰,这是一个存在一些技术挑战的地质层;一个位于上莱茵河地堑,目标是断层带,必须仔细考虑诱发地震的风险。后验风险评估突出了这些类型项目的主要问题,两种案例之间的比较强调了工具的灵活性,以及​​根据分析目标呈现结果的不同方式。根据用户需要选择最佳结果显示的可能性。介绍了两个案例应用,一个在巴黎盆地,考虑针对 Upper Trias 的双峰,这是一个存在一些技术挑战的地质层;一个位于上莱茵河地堑,目标是断层带,必须仔细考虑诱发地震的风险。后验风险评估突出了这些类型项目的主要问题,两种案例之间的比较强调了工具的灵活性,以及​​根据分析目标呈现结果的不同方式。一个位于上莱茵河地堑,目标是断层带,必须仔细考虑诱发地震的风险。后验风险评估突出了这些类型项目的主要问题,两种案例之间的比较强调了工具的灵活性,以及​​根据分析目标呈现结果的不同方式。一个位于上莱茵河地堑,目标是断层带,必须仔细考虑诱发地震的风险。后验风险评估突出了这些类型项目的主要问题,两种案例之间的比较强调了工具的灵活性,以及​​根据分析目标呈现结果的不同方式。
