To meet the industrial heat demand in a sustainable way it is necessary to extract geothermal energy from greater depths than has been done so far. Compared to conventional deep geothermal energy, for Ultra Deep Geothermal (UDG) energy we are looking for much higher temperatures of at least 150°C. Such high temperatures are not feasible for the currently existing geothermal plants in the Netherlands, but for industrial application and the production of electricity values of 150°C and more are essential.
Non-proprietary study of Ultra Deep Geothermal
T&A Survey has done research to the potentials and risks of Ultra Deep Geothermal in the Netherlands, focussing mainly on the Lower Carboniferous. Using seismics, borehole information and literature, we developed a unique spatial insight into the presence of layers of potential reservoir rock at UDG depths in the Netherlands. In addition, we performed a petrophysical analysis in order to determine the quality of the reservoir.
Based on the results and the risk assesment, a detailed map of UDG potential has been developed. With what we have learned form the research, we will be able to fulfill an advisory role in future UDG project. Pleas contact us for more information!
Green Deal for UDG
The Dutch government, research institutes and seven business consortiums on June 19th 2017 signed the so called Green Deal Ultra Deep Geothermal Energy, stating that 30% of the industrial heat demand can in the future be met by UDG. This is an important step towards mapping the UDG potential in te Netherlands and lays the foundations for further development of the technology.

Deep seismic research
Since the 1990s, 3D seismic research has been carried out in areas of interest for oil and gas exploration, such as Groningen and Westland. 3D seismic research shows the deep structures in the earth's crust with the highest quality and coverage. 2D seismic research was carried out all over the Netherlands until the 1980s, but the coverage and quality of this research are lower.
