Correlation of mud filtrate resistivity to mud resistivity
Input(s)
\(\mathrm{K}_{\mathrm{m}}\): Mud Coefficient Varies with Mud Weight (dimensionless)
\(\mathrm{R}_{\mathrm{m}}\): Mud Resistivity (ohm m)
Output(s)
\(\mathrm{R}_{\mathrm{mf}}\): Mud Filtrate Resistivity (ohm m)
Formula(s)
\[
R_{m f}=K_{m} *\left(R_{m}\right)^{1.07}
\]
