Results and Discussion This section presents the rock properties before and after maturation, and the results for one shale sample are discussed. First, the shale properties before conducting...

..., in bioclastic limestone, shell fragments are resistive and dense (appear as resistive spots or patches) while the leached parts of the same shells could be conductive / porous (appear as conductive spots or patches). Including textural information in porosity and permeability, calculations in carbonates...
