T&A has performed a non-proprietary study into the potential and the risk of Ultra Deep Geothermal Energy (UDG) in the Netherlands. The emphasis is on the Dinantian Limestone, a promising reservoir for UDG at a depth of about four kilometers. For UDG we are looking for temperatures of at least 150 °C. Such temperatures are not feasible for current geothermal systems in the Netherlands, but are essential for various industrial applications and for the production of electricity. Based on the results from these studies and the detailed risk matrix, we have mapped the potential and the risk of UDG for the entire country.
February 28 Trias Westland performed the production test in the Lower Cretaceous Reservoir. Water from a depth of 2.3 kilometers was pumped up. The test went very well. The hot water flowed very smoothly into the basin and the gas in the water was flared off. Samples have been taken and measurements have been made to determine, among other things, the pressure and temperature. With this information the project team can start with the realization of the heat network. The exact potential of the geothermal doublet will be known at the end of April, when the second well has been drilled and tested.
