Cased-Hole Logging

X-Y Production Dual Caliper

X-Y Production Dual Caliper

Inner tubing diameter measurements

X-Y Production Dual Caliper (PDC). The X-Y caliper provides simultaneous measurements in the X and Y axis, resulting in an accurate assessment of the geometry of the tubular being logged.


Key Features

· Determination of X-Y diameters in horizontal wells
· Correction of spinner derived fluid velocity for varying
completion diameter
· Detection of serious deformation or corrosion
· Detection of scale build-up
· Depth correlation
· Combinable with other GE Ultrawire™ tools
· Memory or surface read-out operation
