The equipment was development by AO NPP VNIIGIS in cooperation with OOO NPP INGEO and OOO NPP INGEO-Service
is designed to measure the thermal neutron flux caused by fast neutron moderation in the rock to provide the formation total waterlogged porosity and lithology within different kind of wells.
Features and Advantages
- downhole tool small diameter;
- pulses miscount elimination thanks to recording channel “dead time” correction for analog signal transmission by bipolar pulses of 10ч20 microsec due to static adjustment;
- high-efficiency neutron counter with helium filling agent
