box for oil and production logging tool X-Y Caliper PDC logging tool
The dual caliper has a pair of caliper arm mechanisms set at 90° to each other for measuring the inside casing diameter in the X and Y axes. The caliper is spring loaded and follows tubing ID while running in hole. It opens fully on leaving the tubing to enter the casing. Each arm operates as an independent unit exerting a constant radial force in any casing diameter. The tool is used to correct spinner-derived fluid volumes in varied hole sizes, or to identify casing deformation and areas of scale build-up.
Pulse/Manchester code/Wstbus options, compatible with different surface systems Fully collapsible down to tool diameter for running into and pulling out of the hole No scraper seal profile included, increase job safety Can be logged with other tools Measure while centralized
