Well Log Analysis Borehole Resistivity Logging Tool

Well Log Analysis  Borehole Resistivity Logging Tool

GDC-1 resistivity logging tool is an instrument used to measure the apparent Resistivity of drilled rock formations. The surface instrument is connected to the underground electrode system and use PC to measure parameters of apparent resistivity and natural potential.

There are two voltage measurement channels for apparent resistivity measurement, and two apparent resistivity curves (gradient + potential) can be recorded simultaneously.
