AN EU INITIATIVE TO ESTABLISH A RISK ASSESSMENT FRAMEWORK FOR HIGH TEMPERATURE GEOTHERMAL WELLS

Abstract

In high temperature geothermal power application, it is essential to maintain the well integrity despite of aggressive nature of geothermal fluids and high temperatures adversely affecting the conditions of well elements. To extend the lifetime and performance of such wells, the GeoWell project commenced in 2016. The project aims to develop and test reliable, cost effective and environmentally safe completion and monitoring technologies to reduce risk and operation costs of high temperature (⁓450°C) geothermal wells. As part of this project, this study outlines a conceptual framework for risk assessment and management of high temperature geothermal wells.
