1 PagesMReX obtained accurate porosity measurements in high-salinity mud Challenges ? Logging risk in 0.013 ohmm mud resistivity and high salinity ? High temperature of 128°F (53.3°C) ? 210 kppm sediment concentration ? Small borehole in deepwater well Results ? Obtained critical porosity measurements that agreed with the density/neutron porosity ? Identified gas reserves ? Reduced formation testing costs approximately $500,000 USD A major offshore operator in the South China Sea needed to obtain accurate NMR porosity measurements that would agree with density/neutron porosity measurements for the formation lithology. The company wanted to identify the gas zone in a deepwater well with a very low mud resistivity of 0.013 ohmm. The best results would
