Table 1 Porosity and density data for wells D1 and B4 obtained from laboratory measurements and well logs. The table includes porosity values (\(\phi\)) and bulk density (\(\rho\)) for both core samples and log data, as well as mineral density estimates from X-ray diffraction (DRX) and volumetric calculations for both the sample and well depth.
