Following news on disappointing low water rates achieved from a drilled geothermal well, the Geretsried geothermal project is now looking at drilling a sidetrack for the well hoping to find sufficient water.
The well drilled in Gelting/ Geretsried, is with a depth of 6,034 meters (19,800 feet) the deepest in Europe. The project plans to provide 5,000 households in the area with power. But instead of 100 to 120 liters/ second, first pump tests only derived around 10 liters/ second. This is insufficient for an economic operation of a plant.
Now Enex Power, the developer, is planning to drill a sidetrack to target different zones hoping to struck water. The sidetrack is expected to be drilled at a depth of 3,000 meters down to 5,500 meters.
A nearby project, already is looking at adapting its project as the lack of water for the Geretsried project might also indicate similar conditions for this project.
