WebPorosity ( ) was calculated from the LWD density log. = ( b - g ) / ( w - g ), where b is the log value (bulk density), and assuming a water density ( w ) of 1.035 g/cm 3. This porosity (Fig. F24 ) shows an overall improved fit to core porosity data between 60 and 687 mbsf compared to the use of constant grain densities, with the LWD porosity ... Webresistivity in shales, which is due to the presence of bound water in clays that undergo surface conduction. The degree to which the sandstones have higher resistivities depends upon (i) their porosity, (ii) their pore geometries, (iii) the resistivity of the formation water, (iv) the water, oil and

WebIn particular, it enables definition of the main lithological structures within the aquifer. The final ERT static model delineates a relatively high-resistivity, low-porosity, intermediate-depth layer throughout the investigated aquifer volume that is consistent with results from well logging and seismic and radar tomography models.
