Product Description

North Seeking Continuous Fiber Optics Gyro

 

Introduction

 

The Casing Drilling Directional System integrates existing MWD technology to measure real-time attitude data during casing drilling and transmit it to the surface. Drilling and casing operations can be performed simultaneously to save time and cost.
