Using basin modeling for geothermal energy exploration in the Netherlands - an example from the West Netherlands Basin and Roer Valley Graben

The West Netherlands Basin and Roer Valley Graben in the Netherlands have been studied in detail by several authors over the years (Geluk, 1990; Zijerveld et al., 1992; Geluk et al., 1994; De Jager et al., 1996; Van Balen et al., 2000a; Van Balen et al., 2002; Worum and Michon, 2005; Worum et al., 2005; Luijendijk et al., 2010). A lot of the geological research was focused on conventional oil and gas exploration. However the exploration focus currently shifts towards unconventional energy such as geothermal energy or shale gas. For geothermal purposes new questions with regard to porosity/permeability and temperature of sandstone aquifers and the related thermal conductivity have surfaced. More detailed knowledge of eroded thicknesses and the influence of the erosion on the geological framework is important for predicting e.g., porosity / permeability in sandstones and shales. The correct determination of these parameters, especially in a more regional context, are essential for successful exploration of geothermal energy. We use basin modeling to study the thermal and structural evolution of the study area and to determine the necessary parameters for geothermal energy also between wells.
