1. n. [Production Logging]
The loss of material on the inside or outside of a casing or tubing due to corrosion. Monitoring wall loss in situ helps determine when the pipe may be at risk for leaking or failure. Wall loss is determined by comparing casing or tubing thickness measured by electromagnetic, acoustic resonance or mechanical methods with either an earlier measurement or an assumed value.
Synonyms: metal loss
Antonyms: metal gain
