Abstract
Logging tools for electromagnetic flaw detection, developed in VNIIGIS, provide inspecting well conditions with and without (EMDS-TM-42 tools) lifting of compressor tubing. In case of inspecting with lifting of tubing (EMDS-S tool) we can observe holes, made by drilling perforation tool. Examples of logging investigations in Russia, Oman and China are presented.
