What is Shaly Sand Porosity Calculations about?

Here are the steps to solve this shaly sand problem: 1. Identify hydrocarbon zones by crossplotting neutron-density logs (Fig. 11) and looking for points above the clean matrix line after shale and gas corrections. No hydrocarbon zones identified. 2. Calculate Rw from deep resistivity logs (Fig. 10) using the salinity and BHT logs. Rw=2.15 ohm-m. 3. Crossplot neutron-density logs (Fig. 11). Make shale correction using given Vsh of 25%. Read φe. 4. Make same correction on total porosity curve to obtain
