is designed for rock neutron parameters detection, oil/gas saturation estimation after some neutron lifetime (effective capture cross section Σa) and water-saturated porosity coefficient determination (water content).
Application
Unlike the pulsed neutron gamma-ray logging tool TzSP-2INNK-43M is effective for enhanced GR registration in fiberglass well system.
TzSP-2INNK-43M and TzSP-2INNK-43 tools can be combined with a collar locator with the LM-GK-43 channel.
TzSP-2INGK-43M* logging tool is to be run with GECTOR, VULCAN V3 and KEDR log recorder with one-core or three-core cable.
*The tool is certificated.
