Description
The Electrical Resistivity probe measures gradient resistivity,normal resistivity and spontaneous potential (SP) simultaneously. Users can log resistivity profiles with different depths of investigation and gain information about permeability, porosity, water quality and geological formation properties.
Operating Conditions:Uncased；Borehole Fluid:Water or Mud
Features & Benefits
1, The probe will digitize the measured information of the stratum and transmit it to the surface to avoid the effect of the cable on the measurement data.
2, Constant power, adaptive measurement, no manual operation.
Applications
Facies changes；Quantitative geological formation properties
Identification of hydrostratigraphic units
Aquifer thickness；Water quality
Identification of hydrocarbon intervals
Detection of ore body zones；Bed boundary analysis
