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:
• register 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.
Delivery in complete set: downhole tool, interface unit, technological software, maintenance tool, spare parts and accessories, certificate, operating manual.
