Borehole Logging Tools Geophysical Logging Equipment Underground Water Well Logging Tools Electrical Logging System Downhole Logger For Gamma And Resistivity
Application of logging tool
(1) Divide the rock stratum in detail and accurately determine the depth and thickness of the rock stratum.
(2) Determine lithology and porosity.
(3) Divide the reservoir and evaluate its oiliness.
(4) Make stratigraphic comparisons, and study structural and stratigraphic deposition issues.
(5) Investigate the technical conditions in the well, such as well deflection, well diameter, and cementing quality.
Description
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.
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
