SP Resistivity Well Logging Equipment 3



DX-3Dr  Natural Gamma & Electrical Resistivity Probe


The Natural Gamma & Electrical Resistivity Probe measures natural gamma16” Normal & 64”Normal ResistivitySpontaneous 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 ConditionsUncasedBorehole FluidWater or Mud.


Features & Benefits:


1The 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.

2Constant power, adaptive measurement, no manual operation.





Facies changesQuantitative geological formation properties


Identification of hydrostratigraphic units
