Abstract

The aim of the project described here is to ascertain the geothermal potential of deep-lying aquifers in The Netherlands. To this end an inventory of relevant data has been assembled. For hydrocarbon, coal and salt exploration purposes a vast amount of data on the subsurface geology has been collected by the industry. The country is situated just to the north of the Variscan fold belt of Middle Europe. Younger orogenic periods gave rise only to light folding, and the beds of carboniferous and younger ages therefore lie relatively undisturbed. Faulting and substantial vertical movements have occurred however. The main aquifers are all sandstones. They are: - Vlieland Formation - Rijswijk Sandstone, Berkel Clastic and Rijswijk Sandstone Members (Early Cretaceous) - Middle Bunter and Main Buntsandstein Formations (Triassic) - Upper Rotliegend Group - Slochteren Formation (Early Permian) Depths are between 2000-3500 m, temperatures around 100 degrees C. Porosity and permeability are generally of primary origin. In certain areas the burial history led to substantial compaction and diagenesis, resulting in deteriorated reservoir characteristics. Transmissivities are of 10 or more. Because there is still much competition in the search for more oil and gas, this study does not contain detailed structural information. Also the amount of actual test results from wells is limited. Nevertheless a fair insight into the geothermal potential has been obtained. Temperature maps and a statement of geothermal resources and reserves are included.
