Well integrity is a fundamental concept in the oil and gas industry, encompassing the structural and operational soundness of a well throughout its entire lifecycle, from drilling and completion to production and eventual abandonment. It ensures that barriers such as casing, cement sheaths, and wellhead systems effectively contain reservoir fluids, pressures, and hydrocarbons, preventing uncontrolled releases that could lead to environmental pollution, safety hazards, or economic losses. Regular assessments, including acoustic logging, pressure integrity tests, and corrosion monitoring, are essential to identify potential issues like annular leaks, casing failures, or cement degradation early on. By prioritizing well integrity, operators can mitigate risks associated with blowouts, cross-flow between formations, and subsurface migrations, ultimately safeguarding personnel, assets, and the surrounding ecosystem while complying with stringent regulatory standards.

EMDS (Electro-Magnetic DefectoScope Tool)

The Electromagnetic Defectoscope Tool (EMDS) is a specialized wireline logging instrument designed for non-destructive evaluation of tubular integrity in oil and gas wells. It employs electromagnetic principles—typically pulsed or transient electromagnetic fields—to quantify wall thickness, detect metal loss, and identify defects such as corrosion, cracks, deformations, and perforations across multiple concentric casing strings.

✅ Method: Electromagnetic induction via transmitter and receiver coils. A pulsed magnetic field is generated, inducing eddy currents in the pipe walls. Receivers measure field distortions to calculate thickness and anomalies. Gradient-based noise discrimination enhances signal clarity in multi-string environments.

✅ Barrier Coverage: casing 1 and 2 quantitative and casings 3-4 qualitative, based on tool specifications.

MTT (Magnetic Thickness Tool)

The Magnetic Thickness Tool is designed to detect fluctuations in the metal thickness of pipes. It incorporates twelve sensors affixed to the inner surface of bow springs, enabling smooth passage through tubing while inspecting casings as large as 7 inches. The device produces an oscillating magnetic field that penetrates the casing wall, moves a brief distance externally, and then re-penetrates to reach the sensors. Metal thickness impacts the wave’s speed and intensity, where slimmer walls promote swifter transmission and minimal signal damping. Such discrepancies allow for the identification and measurement of anomalies, including corrosion pitting and general metal degradation.

MFC ( Multi Finger Caliper)

ur Multi-Finger Caliper (MFC), equipped with 24 to 60 high-resolution calipers, delivers unmatched accuracy in measuring wellbore tubing and casing. Using multi-sensors, it detects corrosion, erosion, deposition, and deformation, providing a clear image of casing conditions especially metal loss.
