The equipment was development by AO NPP VNIIGIS in cooperation with AO NPF GITAS
is designed for reservoir saturation nature determination, lithological profiling, abnormal thermal neutrons absorbent estimation (Cl, H, Si, Ca, Fe, Mn, Ni, Co, et al.), estimation of scattering, absorbing neutron and gamma-ray parameters as well as their ratio.
Registered information can be used for:
- reservoir saturation character determination;
- downhole cross-section lithological breakdown;
- element content estimations, which anomalously absorb thermal neutrons (Cl, H, Si, Ca, Fe, Mn, Ni, Co and others);
- estimations of dissipative and absorptive neutrons and gamma-radial parameters in rock and their correlation.
Features and advantages:
- registrate gamma-radiation in wide energy range, increasing SNGK methodical possibilities;
- the tool is made in the form of digital two sonde module, which contains two multichannel energy spectrometers.
