en.Wedoany.com Reported - A comprehensive reservoir study provides new insights into the direct use of low-temperature geothermal energy in the southwestern Netherlands. The study was conducted by Sproule ERCE and Witteveen+Bos, commissioned by Energie Beheer Nederland (EBN) and the provinces of South Holland, North Brabant, and Zeeland.
The primary data for the study came from an exploration drilling conducted in the spring of 2024 at Krukweg in Heijningen, reaching a depth of 834 meters, which confirmed formations suitable for geothermal fluid extraction. Combined with data from the Oranjeoord-01 research well and seismic information, an integrated static subsurface model was constructed, enhancing understanding of the permeability, facies distribution, and geomechanical behavior of the Brussels Sandstone Member. An economic flow rate of 150 m³/h was determined, with a production temperature of up to 40°C, corresponding to a single doublet capacity of 5 MW, suitable for district heating, greenhouse horticulture, and building heating. These findings highlight the potential of low-temperature geothermal energy for direct use in the southwestern Netherlands.
The study identifies three areas with geothermal potential: favorable subsurface conditions in Goeree-Overflakkee, South Holland; clear opportunities for heat networks in Zevenbergen, Breda, and Made in West Brabant; and moderate subsurface conditions in Zeeland, though economic feasibility may exist for greenhouse horticulture areas in northern Tholen and Schouwen-Duiveland, despite the industry's preference for high-temperature geothermal energy. Municipalities or operators can use this study to apply for a geothermal energy search area allocation, further developing low-temperature geothermal resources in the southwestern Netherlands.
