Corrosion Logging services
Pipe corrosion is a normal occurrence in the hostile environment of oil and gas drilling wells, and monitoring it enables prompt intervention to avoid leaks, environmental damage, or equipment malfunctions. The inner diameter and wall thickness measurements are used to estimate pipe corrosion.
Technology:
To study tube and casing corrosion, many instruments might be employed. This will be determined by the size of the project and the goals that must be met. Different tools may yield different results, such as internal or external corrosion, casing or tube damage, buckling, scale build-up, and metal thickness.
Multi Finger Callipers (MFC)
Multi Finger Callipers is a device that uses numerous arms to measure the diameter of the interior wall of a casing or tube. The caliper can detect minor changes in the pipe wall by utilizing a high number of arms or fingers. The primary goal of the measurement is to detect deformations, scale accumulation, and metal loss due to corrosion. There are 18-, 24-, and 40-50 finger calipers available. MFC comes in a variety of sizes to accommodate the cased hole diameter. Our system transmits data in real-time over a wireline cable. MFC may be used in conjunction with memory techniques such as NIT, DCCT/TCCT, and Sampling.
Electromagnetic Casing Thickness Corrosion
The Electromagnetic tool generates in induction currents as a pulsed magnetic field in the surrounding tubing and casings and the subsequent recording of the electromotive force (EMF) decrease in pipes. Available for double and triple casings.
Direct Applications:
- Up to three Casing Quantifying thickness and 4th qualitative.
- Integrity of casing and tubing strings.
- Integrity of threaded joints, collapses and faults, external and internal corrosion and abrasive wear.
- Casing and well stability.
- Casing buckling and tortuosity, stress/strain state of support elements.
- Wellhead equipment and pump and compressor equipment conditions (safety valve, packer, perforated connection pipe, etc.).
- Bottom-hole region and equipment conditions (perforated intervals, filter zone, rock conditions, sand plugs, wellbore fluid level and heavy hydrocarbon and salt deposits).
