Cementation in the Dutch upper Rotliegend siliciclastic reservoirs
conference paper
The Permian Rotliegend Slochteren Formation is a prolific gas bearing interval in the Netherlands. However, their reservoir porosity and permeability can be locally severely degraded by diagenetic pore-blocking cements. This work focusses on the cementational control on the reservoir quality. The drivers and causes of cementation and its effect on the reservoir quality were studied by integrated analysis of petrography, basin modelling, fluid flow systematics, sedimentology and geochemistry. Results indicate that cementation is both environmentally and structurally controlled with superimposed influence of Rotliegend meteoric, Zechstein and Carboniferous fluids. Although mineral authigenesis and reservoir quality have locally different principal drivers, the projection of regional models onto the whole of the Dutch Upper Rotliegend can improve the prediction of authigenesis at yet unexplored locations.
