Description

The 40GRP-1000 combination probe is ideal for slimline, one-pass, hydrogeological studies, lithology work, uranium exploration, and general borehole formation data. The totally digital probe combination measures 16, 64 inch (0.4, 1.6 meter) normal resistivity, single point resistance, self-potential, and natural gamma. It operates with the newest LoggerSuite digital logging system and software.

The 40GRP-1000 is a standalone tool. The normal resistivity measurements, single point resistance, and self-potential measurements are designed for surveying open (uncased) fluid-filled boreholes. Gamma measurements can be taken in any borehole environment.

Applications

  • Bed boundary analysis
  • Facies changes
  • Quantitative geological formation properties
  • Identification of Hydrostratigraphic units
  • Aquifer thickness and Water quality
  • Hydrocarbon intervals, Ore body zones, In-situ Uranium assay
  • Fluid contaminant monitoring, Soil horizons, Grain size estimation

Operating Conditions
