Objectives: The goal of WP2 is to address market needs for innovative solution and successful implementation in geothermal wells. A market analysis involves quantitative and qualitative assessment, including market size for various bedrocks or sediment conditions. Emphasis will be on future aspects of deep geothermal wells, statistics on casing failures in medium to high enthalpy geothermal wells and related temperature/pressure conditions.
The work is divided into three tasks.
- Task 2.1 Geothermal wells above 200°C. Market analysis of flexible coupling in high-enthalpy geothermal applications aiming for high-temperature geothermal wells above 200°C up to supercritical regime.
- Task 2.2 Geothermal wells 100-200°C Market analysis of flexible coupling in low to medium-enthalpy geothermal applications aiming for low temperature geothermal areas where temperatures are in the range of 100-200°C.
- Task 2.3 Deep geothermal wells with casing depth > 2000 m Challenges of using flexible coupling in deep cased wells with casing lengths of 2000 m and deeper.
