Assessing Reservoir Potential Of Devonian-Carboniferous Carbonates In The Dutch Subsurface

Analysis of a regional dataset of (old and new) wells and seismic data in the Dutch subsurface, in comparison with nearby outcrops and with analogue carbonate systems elsewhere have yielded new, more positive, insights into the original reservoir development and the possible present-day range in reservoir quality of the underexplored Devonian Kyle Limestone and the Dinantian Carbonates. Large variations are present, both between the two systems and within the Dinantian Carbonates. These insights support predictions of reservoir quality in these strata. At the same time, the results of modelling of variations in seismic character of these carbonates, as a function of composition, porosity, pore fill and overburden properties, can be used in the reprocessing and interpretation of existing seismic and in the acquisition of new seismic data. This will be part of a nation wide study into the potential of Ultra Deep Geothermal projects in carbonate reservoirs.
