KSP-GK-43 INTEGRATED DOWNHOLE ELECTRICAL AND GAMMA-RAY LOGGING TOOL

The equipment was development by AO NPP VNIIGIS in cooperation with OOO NPP INGEO and OOO NPP INGEO-Service

Designed for simultaneous measurement of apparent electrical resistance (ρa), spontaneous polarization potential (SP), exposure dose rate (EDR) of gamma radiation with a quantum energy of 0.03-3 MeV (GR).

The ρa measurement is performed by the method of excitation of the medium with an alternating electric field using electrodes AB and measurement of voltage drop on electrodes MN. SP measurement is performed when the external electric field is off.

The downhole tool is to be run with VULCAN V3 log recorder or similar.

Operates with one-core (SP record restriction) or three-core logging cable.The dimensions of the sonde are made upon request.
