Abstract

Currently six geothermal doublets are realized in the WNB. Five of these doublets target the same Lower Cretaceous fluvial sandstone interval, the Nieuwerkerk Formation. About 40 exploration licences are granted. Many of them also have sandstones in the same fluvial interval, the Nieuwerkerk Formation as a target. To successfully and efficiently produce geothermal energy from this fluvial sandstone interval, the distribution and internal architecture of the sandstone bodies must be better understood.
Fluvial sandstone reservoirs are composed of stacked meander belts and floodplain fines. Net-to-gross, orientation and stacking pattern of the channel belts is of major importance for the connectivity between the injection and production wells in fluvial sandstone reservoirs
