Density-magnetic resonance (DMR) method is a well logging method for evaluating gas-bearing reservoirs. The method combines total porosity from the combinable magnetic resonance tool (TCMR) and density log-derived porosity (DPHI). DMR method provides a new petrophysical equations for gas-corrected total formation porosity and flushed-zone gas saturation. The DMR gas-corrected total porosity are used in volumetric calculations to provide more accurate reservoir volume estimates than previously possible. Also, more accurate formation gas saturations can be computed when using gas-corrected total porosity in conjunction with deep-reading resistivity tools.
