is designed for detailed casing string conditions survey, defects form and size identification; cumulative and drilling perforation holes detection, wall thickness determination within certain sectors
Features and Advantages
- casing small defects identification (longitudinal cracks and cross cracks and holes);
- identification of local reductions in casing wall thickness within corrosion sectors and mechanical wear zones (including key seats);
- cumulative and drilling perforation holes detection.
