Product Description

North Seeking Fiber Optics Gyro While Drilling

 

Introduction

The North Seeking Fiber Optics Gyro While Drilling "Roar" system was designed based on the LIUHE NS-FOG. The Roar tool is designed and built to withstand harsh drilling conditions and is operated in a similar manner as a conventional MWD system.

 

When the pumps are turned off, the tool will seek North and take a survey and store it in its memory. After the shot is taken and the pumps are turned back on, the tool will transmit via mud pulse telemetry; the stored survey data as well as all quality control flags to verify the quality of the shot.

 

After the survey is transmitted, the tool will continue sending information like INC, GTF, ERH. The tool stores every shot it takes, while download, for use later when retrieved at surface
