  • Reservoir quality in siliciclastic reservoirs is generally impacted by the depositional environment and the presence of authigenic components. However, the distribution of clay coatings within depositional environments is unclear, although they are a main controlling factor in porosity preservation. We show that the distribution and clay coat coverage is not purely dependant on the depositional environment, the grain size, sorting and the stratigraphic position. The application of generalized correlations to reservoir quality modeling highlights the necessity for a purpose-built database, calibrated by analog samples from core material.
