The first geothermal plant in Denmark was established in 1984 near the town of Thisted (Fig. 1). For nearly 30 years the plant has successfully produced c. 43°C hot water (surface temperature) from a highly permeable sandstone reservoir in the Late Triassic to Early Jurassic Gassum Formation and used the heat from the geothermal water for district heating. The 45°C hot water (formation temperature) is pumped up from a vertical production well, Thisted-2, from a depth of c. 1250 m and the cooled water (c. 12°C) is re-injected into the formation through a vertical injection well, Thisted-3, located 1.5 km east of the production well.
