    Wpływ kompakcji na właściwości zbiornikowo-filtracyjne skał miocenu Przedgórza Karpat
    (2008) Twardowski, Kazimierz; Traple, Jacek
    The influence of compaction on reservoir-filtration properties of rocks was analyzed on the example of autochthonous Miocene sandy-clayey beds of the Carpathian Forefield. The effective porosity and absolute permeability values for rock samples collected from the wells in the Przemyśl area were analyzed. The analyzed parameters were observed to change for a vast range of rock depth (to over 4000 m), and the results were compared with the mechanical compaction modeling results. The discrepancies can be explained by various clay content in the rocks and also chemical compaction processes, mainly their diagenetic cementation with carbonates.
