Description
A-One Oil Electro Magnetic Interference Tool (EMIT43C) it can inspect changes in the wall thickness of metal tubulars, to evaluate the corrosion, perforations, or other forms of damage.
The new generation of EMIT43C 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.

Features
◆ The Electro Magnetic Interference Tool (EMIT43C) operates in a dense interval mode, identity up to 127 test curves, and utilizes a brand-new graphical algorithm to present the test curves in the form of a spectrum.
◆ It adopts a 13-core quick connector, can be easily and rapidly connected to Gamma, Well Temperature, CCL, Multi-arm Caliper, MCBL , Downhole "Eagle Eye" and other tools.
◆ It can test multiple layers of casing, up to 3-4 layers of tubing.
Applications
◆ Casing integrity evaluation: To detect casing corrosion, wear, or mechanical damage.
◆ Casing inspection: To evaluate the wall thickness variations of production tubing.
◆ Well intervention decision support: To Provide the key data for well intervention operations.
This Electro Magnetic Interference Tool (EMIT43C) is particularly suitable for wellbore integrity inspection in old oil fields, highly corrosive environments, water-injected oil fields. It is a key tool for oil and gas field management and safety evaluation.
Why choose A-One Oil?
The Electro Magnetic Interference Tool (EMIT43C) 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.
