1000m Borehole Geophysical Logging and Well Log for Ground Water and Environmental Study
Natural Gamma & Electrical Resistivity Probe
The Natural Gamma & Electrical Resistivity Probe measures natural gamma,16" Normal & 64"Normal Resistivity,Spontaneous Potential (SP),Single Point Resistance(SPR),Temperature. 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.
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
