Question 3: A clean siliciclastic sandstone has 15% total porosity and is saturated with 30% gas, 42% oil, and 28% fresh water. You can assume gas density =0.1g/cc, oil density =0.8g/cc, quartz density =2.65g/cc, limestone density =2.71g/cc. (a) What is the reading of the apparent density porosity log in waterfilled sandstone porosity units? (SHOW YOUR WORK) % SS (b) What is the reading of the apparent density porosity log in waterfilled limestone porosity units? (SHOW YOUR WORK) % LS (c) What is the reading of the apparent neutron porosity log in waterfilled sandstone porosity units? (SHOW YOUR WORK) % SS (d) What is the reading of the apparent neutron porosity log in waterfilled limestone porosity units? (SHOW YOUR WORK) %LS
