Abstract
Lower Carboniferous Dinantian Carbonates are “hot”; they form the target reservoir for active and future geothermal projects onshore the Netherlands, while at the same time the exploration for hydrocarbons in this reservoir has revived in the Dutch and British southern North Sea sectors. This reservoir is, like most carbonates, heterogeneous in many ways and at different scales. At the same time, the seismic and well datasets are sparse and of variable quality. Learning from geological analogues is therefore of key importance to be able to predict flow performance. Proper and consistent assessment and mitigation of the technical risks is important to support business cases and subsequently execute projects in a safe and sustainable way. This again requires taking the learnings from elsewhere into account. The Dutch government approved and sponsors an extensive geothermal exploration program which comprises a large number of studies. Results of a recent seismic modeling study support the characterization of the carbonates. The geothermal exploration program should result in the definition of three pilots for geothermal projects in Dinantian Carbonates below four kilometers depth.
