Downhole Casing & Tubing Tractor (CTT)

Applications

● Convey downhole tools along horizontal or highly deviated wells

Introduction

CTT is used in lateral well or high-inclination well to send toolstring. Toolstring includes Production Logging Tools (PLT), casing check tool, CBL Tools, etc. The CTT uses a single-conductor wireline to supply power and transmits signals. With the surface control panel and software, operator could know about speed, conditions, etc. An Electric Centralizer is used in CTT, and it can close electrically that made CTT through horn successfully.
