Geophysical Borehole Logger Wireline Logging Equipment Well Logging Tool Borehole Logging Probes For Natural Gamma And Resistivity Logging comes with a wireline cable winch. The winch is used with the borehole probes for positioning in the well. A 220/110 volt power supply is required for operation. Using the borehole logger, geophysical sensors can be placed in the formation providing higher resolution and accurate information over surface measurements.
Features:
- Real-time color logs on your PC monitor using Logger Suite software.
- Universally-configured depth-measuring system
- Works with digital tools

1. To delineate the aquifer from the water barrier and to determine its depth and thickness.
2. Determining the porosity and permeability of the aquifer and estimating its water influx.
3. To study the mineralisation of the formation water
4. To study the direction and velocity of groundwater flow, etc. Depending on the task, resistivity logging, natural potential logging, radioactive logging and acoustic logging can be applied individually or in combination. For example, the use of resistivity logging to divide the aquifer and water barrier; the use of natural potential logging to study the mineralisation of groundwater; the use of charging or isotope method to study the flow of groundwater velocity and direction; through the measurement of the resistivity of the saline mud in the well to determine the amount of water surge (generally known as diffusion method). Hydrological logging is of some significance in finding water for industry and agriculture and in solving hydrogeological and engineering geological problems in mining areas.
