is designed for natural gamma-ray spectrum registration, capture gamma-rays spectrums and thermal neutrons flow density at two distances of a sealed fast neutron radioactive source.

Description

Features and advantages

• geological cross-section lithology; lithologic model calculation and  argillaceous deposits  specification;
• reservoir identification and porosity coefficient estimation;
• reservoir fluid content/oil and gas saturation coefficient estimation;
• water-oil/gas-oil/gas-water contact location.

Tool includes: downhole tool, interface unit, which provides data transmission according to logging cable, downhole tool power supply and connection with depth sensor, and also NOTEBOOK or on-board computer of logging station.

KSPRK-Sh-90 tool can be exploited with any logging hoist and cable 6 km in length, which is capable to transmit spectrometric signal.
