Experimental simulation of burial diagenesis and subsequent 2D-3D characterization of sandstone reservoir quality [dataset]

High reservoir quality in deeply buried sandstones is commonly correlated with the occurrence of grain coatings that inhibit quartz cementation. The development of reliable models that can predict reservoir quality relies on incorporating quantitative understanding of these diagenetic processes. Hydrothermal experiments simulating burial diagenesis, were integrated with multi-scale x-ray tomography to quantify the 3-dimensional evolution of grain coating volume and porosity with increasing temperature; while microscopic and automated quantitative mineralogy analysis was used to track the associated mineralogical alterations. Additional pore flow simulations allowed the characterisation of the pore-throat and permeability evolution, leading to developing a conceptual model for the impact of a diagenetic overprint on the reservoir quality.
