Aquifer properties

An accurate estimate of the aquifer properties of porosity, permeability and net-to-gross is of utmost importance for calculating the geothermal potential. Two generic workflows were developed for generating the regional porosity and permeability maps:

  1. Cretaceous and older: a data-driven geostatistical method (figure 2).
  2. Paleogene and Nederweert Sandstone Member (RBSHN): mainly based on porosity-permeability-depth relationships due to lack of data.
