COURSE DESCRIPTIONThis course provides an overview of the most critical geomechanical aspects in Geothermal Energy. Attendees will learn about geomechanics principles, concepts, and workflows as they apply to the assessment of the key aspects in Geothermal projects. We will discuss the main geomechanical risks and how they may vary from project to project. We will also address data requirements to effectively de-risk a project as well as the type of models that are best suited to address geomechanical risks and their impact on project performance. Case studies will be covered as practical examples to demonstrate workflows and screening tools.
