Reservoir quality prediction can be considerably improved with an integrated approach between sequence stratigraphy and diagenesis. Here, we demonstrate that the occurrence of low-porosity sandstones (pseudomatrix-rich, i.e. matrix formed by mechanical compaction and squeezing of soft clasts in intergranular pores) deposited in shallow marine settings can be predicted in a sequence stratigraphic framework. These sandstones occur as lags bounding parasequences and, thus may form baffles and barriers for vertical fluid flow, and reservoir compartments between two sandstone bodies of adjacent parasequences. The prediction of their occurrence and precise spatial distribution is, therefore, very useful for production of shallow marine reservoirs.
