Overview


The Dual X-Y Caliper Tool (DCT04) is run centralised in the production logging toolstring. The caliper arms are set at 90° to each other, to measure casing ID in the X-Y axis. The caliper assembly is fully collapsible down to tool diameter for running into and pulling out of hole.

Application

· Determination of X and Y diameters at 90° in cased hole
· Measuring of casing deformation and major corrosion
· Detection of scale deposition in casing or tubing
· Correction of spinner derived fluid velocity

Features

· Combinable with KWTBus
· Non dynamic sealing structure
· Low power consumption
· LVDT sensor
