The Dual Induction Log provides four measurements: Deep and Medium Induction curve, Shallow Focused Laterolog and a Spontaneous Potential curve. It is suitable in high-resistive mud systems.
Application
Detection of filtrate invasion
Calculation of hydrocarbon saturation
Identification of formation fluid contact within the reservoir
Contribution to permeability, lithology and facies analysis
Correlation between wells
Calculation of formation resistivity from shallow, medium and deep resistivity readings
