Product Description

Geophysical Borehole Survey Equipment Geological Water Well Logging Tool Well Logging Equipment 

Product Description

The purpose of well logging is to obtain detailed information about the subsurface geology and the properties of the rock formations surrounding an oil, gas, or water well. It involves the use of various tools and techniques to measure and record data about the physical and chemical properties of the rocks, fluids, and other formations encountered during drilling.

I. System Component:

Main instrument and software,
Winch and cable
Well logging probes

II. Features:

External Laptop (Desktop PC)
For upward logging, also for downward logging
Receive digital signal, analog signal
8 taps of power supply current, Optional
Automatic sampling as per depth interval, sampling interval arbitrarily
