Intelligent Four Arm Caliper Tool (iFC)

Download Spec Sheet

The Intelligent Four Arm Caliper Tool uses four fully independent caliper arms capable of recording high resolution borehole data providing an XY dual-axis wellbore diameter measurement. The measurements from the iFC can be used to perform borehole breakout analysis, calculate accurate volumes and provide important data to aid in evaluating log quality from other sensors. When ran in combination with the iNAV tool, the combined data can be used to generate a 3D representation of the wellbore geometry helping to identify drilling induced borehole defects that can impact drilling practices and completion decisions. The iFC tool is fully compatible with the rest of the Signum Instruments micro slim tool suite and its advanced range of conveyance options.
