METHOD AND SYSTEM TO QUANTIFY DAMAGE TO GRAVEL PACK SCREENS

摘要

A system and method to quantify damage to a gravel pack screen are described. The system includes a flux leakage tool to record electromagnetic field measurements at a plurality of points on the gravel pack screen. The system also includes a processor to obtain the electromagnetic field measurements recorded at the plurality of points and to suppress a baseline signal associated with electromagnetic field measurements resulting from perforations of the gravel pack screen to isolate and quantify flux leakage resulting from the damage to the gravel pack screen from flux leakage resulting from the perforations.
