The Westland geothermal heating plant is located in the southwestern part of the Netherlands, marked by a boom in successful doublet systems for greenhouse heating, tapping into clastic Cretaceous/Jurassic reservoirs at approximately 2 km depth. Trias Westland, a project initiative of Royal Flora Holland, HVC and Westland Infra, aims to drill a geothermal doublet to the 4000 meters deep Triassic Main Buntsandstein for long term geothermal exploitation. The geological feasibility to exploit the Buntsandstein for geothermal is uncertain at this depth. The project aims for better understanding of its hydrodynamic characteristics and has therefore planned an extensive evaluation programme, including logging (including FMI), coring and well testing. The analysis and results of this programme give the base to determine if stimulation is a safe option.
