Single-probe induction logging tool IR-GK1

Appointment

The IR-GK1 single- probe induction logging tool is designed for induction and gamma-ray logging in water wells with registration of active and reactive components of apparent conductivity.

The device is used in an open hole or cased (pipes made of plastic) wells filled with flushing fluid with a resistance above 0.1 Ohm / m or in dry ones. In cased wells, the device strikes the boundaries of the reservoir and the filter from a metal mesh.

Execution

The IR-GK1 single- probe induction logging tool has cable and autonomous versions.
