Ultrasonic Scan Imaging Tool-Slim (USI-S)

Applications

● Casing Inspection (both Thickness and Diameter)
● Ultrasonic Cement Evaluation/ Imaging
● Openhole Borehole Imaging
● Fracture Detection

Introduction

USI-S is slim version USI-V and mainly for small hole and casing. USI-S tool consists of 2 sections: electronic assembly and scanner assembly. USI-S tool is Geovista Telemetry System (GTS ) interface type tool. It can be combined with Digital Data Transfer /Gamma Ray / Orientation Tool (TGO), Octopod Segmented Bond Tool (OSB) and Casing Collar Locator-Slim (CCL-S) tools for casing integrity evaluation.
