The EMDS tool detects the tubing or casing thickness, corrosion, deformation, cracks etc.in tubing, indicating downhole string structure, tool location and detecting the ferromagnetic material (such as casing centralizers, surface casing, etc.) outside casing.

Due to the unique structure and measurement principle, logging can be performed in the course of normal production of oil/water/gas wells, reducing operating cost in inspection and increasing efficiency, giving the extent of damage of casing in time.

Features

• Full function: The damage and thickness of tubing and casing, temperature, gamma, etc. can be measured in just one trip.

• Easy maintenance: Simple mechanical structure, easy disassembly and easy maintenance. 

• Various operating modes: Cascade connection, connection with MFC, etc.or independent operating.
