Description
A-One Oil Electromagnetic Casing Inspection Tool (ECIT43C) is an electromagnetic corrosion measurement tool with an outer diameter of 43mm, capable of being operated through the casing.
It has the unique ability to simultaneously inspect the casing and up to 3-4 layers of tubing behind it. There is no need for costly well workover equipment, nor is there a need to disassemble the completion tubing in a time-consuming and laborious manner, as the integrity of the casing string can be assessed.
The new generation of ECIT43C can evaluate the quantitative thickness measurements and damage detection of up to four concentric tubes. The advanced tool combines a high-power transmitter, improved signal-to-noise ratio (SNR) electronic equipment, and a fully high-configured acquisition module and algorithms. This flexible approach allows for a wide range of assessment applications in different testing environments.

◆ It has no sensitive requirements for the medium inside the test well, offering a wide range of adaptability.
Applications
◆ It can log the highly-deviated and horizontal wells.
◆ It can inspect the inner and outer wall of casing flaw.
◆ It can identify the damage type of casing: horizontal crack, vertical crack, corrosion etc
Why choose A-One Oil?
The Electromagnetic Casing Inspection Tool (ECIT43C) has a set of short ("C") and a set of long ("A") sensors. It adopts the principle of transient electromagnetics, where the transmitting probe conveys high-energy electromagnetic pulses into the surrounding tubing. Based on the physical principles of pulsed eddy currents (PEC), the tool records the composite attenuation of the eddy current signals. These signals are used to evaluate the condition of the pipeline.
The long sensor records up to 127 channels, with decay times ranging from 1ms to 280ms. This captures the rapid attenuation signals of the far-field signals from alloy pipes to large casings. The short sensor has a smaller measurement aperture and a higher vertical resolution for scanning the inner pipe.
