This study uses learnings from successful deep drilling campaigns in three geological settings—IDDP-2 (in a volcanic setting), Molasse Basin (in a sedimentary setting), and United Downs (in a metagranitic setting)—to construct a decision-making tool to reduce risk in the planning stage of deep geothermal drilling projects. In order to create the decision tool, interviews were set up with drilling specialists from each drilling campaign. Interviewees then discussed major decisions made, challenges faced, and solutions found. Then, a decision tool was constructed based on learnings from each study.
The decision tool, which is a click-through tool whose architecture is that of a decision tree, serves three purposes: to provide a flow structure for decision-making that allows users to make decisions that are compatible with one another, to provide advice for decisions in tandem with the use of the tool, and to warn of challenges for the specific geological environment selected and choices made based on each case study. Guidance does not include all possible decisions, nor does it warn of all potential risks in a drilling project but is meant to characterize major decisions and challenges faced in the three representative drilling projects.
In the end, this study seeks to provide well-rounded guidance for deep geothermal drilling. Understanding the risks associated with deep drilling in unconventional environments is essential to decision-making with drilling and avoiding failure. A better understanding of drilling to deep geothermal reservoirs may one day be critical step to solving climate change.
