X-Y Caliper HD Tool (High-Speed Digital)


Provides continuous measurement of independent X and Y internal tubular diameters by means of measurement arms set at 90° apart 


Applications

  • Accurate wellbore internal size measurement
  • Casing and tubing evaluation
  • Defect identification such as scale build up, corrosion, or deformation
  • Identification of completion items
  • Volumetric flow rate calculations can corrections


Features and Benefits

  • Combinable with all high-speed digital (HD) telemetry tools for comprehensive evaluation
  • Collapsible caliper arms for navigation of wellbore restrictions
  • Wide measurement range in a single run


Tool Description

The tool closes to 1.69 in. and opens to 9.00 in., enabling use in both tubing and casing up to 9-5/8 in. OD.
