The equipment was development by AO NPP VNIIGIS in cooperation with OOO NPP INGEO and OOO NPP INGEO-Service
Designed to measure the exposure dose rate (EDR) of natural gamma radiation and volumetric density in 4π geometry when conducting research in wells using a combination of gamma-ray logging (GR) and gamma-gamma density logging (DEN) methods for ores and coal deposits.
The downhole tool is to be run with VULCAN V3 log recorder or similar.
Operates with one-core or three-core logging cable.
