Application MID-SK-100 defectoscope allows to investigate one (central) column, indicating defects and corrosion zones, quantitative diagrams or tables of column thickness in a circumferential direction in millimeters, and also allows to divide column defects into sectors.
Apparatus configuration
• high-sensitive thermometer to register temperature along a borehole while defectograms recording for emphasizing perforation zones and through holes in the column after changes of thermogramms caused by liquid and gas crossflows;
• gamma ray logging module for defect data referencing to geological horizon.
Application field
The tool is used for gas/oil and gas and other well prospecting with casing diameter up to 184 mm/internal diameter from 110 mm/casing thickness up to 12 mm.
