WALL THICKNESS

WALL THICKNESS

At OIS, we offer advanced Wall Thickness Measurement services as part of our comprehensive tubular inspection solutions. Using non-invasive electromagnetic techniques, we accurately assess the remaining wall thickness of casing and tubing in-situ—detecting corrosion, metal loss, and structural weaknesses before they lead to costly failures.

This method provides a reliable, high-resolution log of the casing or tubing condition, helping operators make informed decisions about well integrity, repair, or abandonment strategies.

Alternative Electromagnetic Techniques

In addition to the phase shift method, OIS also employs other electromagnetic-based measurement systems, including:

Casing-potential profile – Measures potential differences along the casing length to infer corrosion activity.

Flux-leakage detection – Identifies anomalies where magnetic fields leak through reduced wall areas, indicating thinning or defects.

These technologies are ideal for detecting internal and external corrosion, pitting, and localized wall loss, even in complex or aged wells.
