Features and Benefits
- Captures data from multiple casing sizes in a single run using 60 independent arms that expand from 6 to 16 in. (152.4 to 406.4 mm)
- Delivers high-resolution measurements with an array of caliper arms and independent radii measurements
- Enables advanced cross-sectional analysis that enhances geomechanical deformation interpretation through use of an eccentricity algorithm and onboard inclinometer package
- Produces graphical cross-sectional and 3D plots of casing ID for easy identification of anomalies and advanced interpretation of deformation after processing through TVision software
- Highlights sources of fluid entry to support the identification of casing anomalies through use of a temperature sensor
The Weatherford extended-range, 60-arm CalView tool provides an accurate internal casing profile from an array of precision-calibrated feeler arms. Each arm provides independent radial measurements that identify drilling wear, corrosion, scale buildup, splitting, buckling, and deformations caused by geomechanical stresses.
Operators can monitor tool response in real time, which enables multiple passes over anomalous features on the casing profile. The long arms deliver measurements in casing IDs from 6.25 to 16 in. (158.8 to 406.4 mm) in a single run while maintaining high accuracy and resolution. Rated to 30,000 psi (206.8 MPa), the tool also can be used to analyze casing deformation and bending through use of an eccentricity algorithm and onboard inclinometer package.
Tool data is exported to Weatherford TVision analysis software, which classifies each casing joint with respect to the worst-case defect found and joint-by-joint well summary. The analysis package can also graphically portray the casing as a 2D cross section or 3D image to highlight anomalies.
