Fluid flow in porous carbonates, theoretical and practical considerations

The fluid flow in carbonates is not flow in homogeneous medium. Such rocks are characterised both with primary and secondary porosities, where the second one is often isotropic only in strictly limited volumes of the depositional unit. Here are discussed several examples taken from the carbonate rocks of the Adriatic Carbonate Platform deposits in Croatia, on millimetre scale, with strong cementation, and partially dissolving and fracturing. The distribution and flow of the fluids in such medium, especially in two-phase liquid system, depends highly on wettability and capillary motion. These values need to be considered for modification of Darcy’s Law, i.e. the values of the filtration coefficient and thickness of the sample.
