Geology of the Upper Jurassic to Lower Cretaceous geothermal aquifers in the West Netherlands Basin - An overview

Reservoir architecture model fo the Nieuwerkerk Formation (Early Cretaceous, west Netherlands Basin): Diachronous development of sand-prone fluvial deposits

The sand-prone fluvial Delft Sandstone Member of the Nieuwerkerk Formation is the main target for geothermal exploitation in the West Netherlands Basin. Uncertainty reduction in the modelling of permeability heterogeneity and connectivity of the sandstone reservoir units is of prime importance in the low-profit geothermal energy market....

Regional geothermal aquifer architecture of the fluvial Lower Cretaceous Nieuwerkerk Formation - A palynological analysis

The primary challenge for efficient geothermal doublet design and deployment is the adequate prediction of the size, shape, lateral extent and thickness (or aquifer architecture) of aquifers. In the West Netherlands Basin, fluvial Lower Cretaceous sandstone-rich successions form the main aquifers for geothermal heat exploitation. Large...

The role of detrital anhydrite in diagenesis of aeolian sandstones (Upper Rotliegend, The Netherlands): Implications for reservoir-quality prediction

The Rotliegend (Upper Permian) reservoir interval in the Southern Permian Basin (SPB) contains low-permeability streaks corresponding to anhydrite-cemented intervals. An integrated study was conducted using core, cuttings, thin sections and well-log data from a gas exploration well and two geothermal wells that target the zone of interest. This...

The Permian Rotliegend reservoir architecture of the Dutch Koekoekspolder geothermal doublet

The Dutch Koekoekspolder geothermal doublet was drilled in 2011 targeting the Permian Rotliegendreservoir. The encountered reservoir properties were less favorable than expected pre-drill. Post-drill integrated evaluation of vintage data and the new data from the geothermal wells resulted in a refined depositional model of the area. The...

Identification and evaluation of CCS sweet spots in the West Netherlands Basin

Carbon capture and sequestration (CCS) is expected to become a serious CO2-emission reduction technology in the Netherlands. The industry- and government-supported national research programme CATO-2 is tasked to investigate the opportunities and feasibility of CCS projects, both onshore and offshore in the Dutch territory. An example of such...

Reservoir modelling of heterolithic tidal deposits: Sensitivity analysis of an object-based stochastic model

Object-based stochastic modelling techniques are routinely employed to generate multiple realisations of the spatial distribution of sediment properties in settings where data density is insufficient to construct a unique deterministic facies architecture model. Challenge is to limit the wide range of possible outcomes of the stochastic model....

Facies architecture of heterolithic tidal deposits: The Holocene Holland Tidal Basin

The size, shape and spatial position of lithofacies types (or facies architecture) in a tidal estuarine basin are complex and therefore difficult to model. The tidal currents in the basin concentrate sand-sized sediment in a branching pattern of tidal channels and fringing tidal flats. Away from the sandy tidal flats the sediment gradually...
