Pipeline Research Council International (PRCI) contracted C-FER Technologies (1999) Inc. ("C‑FER") to conduct a laboratory testing program to determine the Effects of Stress on Casing Magnetic Flux Leakage (MFL) Measurements. Tubing joints with localized defect features were subjected to increments in axial tension to maximum stress levels beyond yield. At various load steps, measurements were made using Baker Hughes’ ("Baker") High Resolution Vertilog Tool (HTVRT) to assess the variation in the defect measurements with load. This report describes the work...
