Comprehensive Modular Equipment for Open-Hole Geophysical Logging
Comprehensive Dual Laterolog Tool E2BKT-D/73 (BKV, BKs, BKM, SP, GR, Temp., Resist.). The tool is designed for simultaneous measurement of the electrical resistivity of rocks using a multi-electrode dual laterolog probe with volumetric electrodes of large (BKV), medium (BKs), and small (BKM) investigation radii. It also includes standard logging probes (KS), measurement of borehole fluid temperature (Temp.), exposure dose rate (EDR) of natural gamma radiation from rocks, and drilling fluid resistivity using a resistivimeter. The tool provides a galvanic channel for measuring spontaneous polarization potentials (SP) in oil and gas wells during drilling.
