Product Description

Rotary Magnetic Ranging System

 

Introduction

This tool is put down to the bottom of the survey point by the pump pressure. After survey completes, the tool will float off to the wellhead depending on its own buoyancy, no winch is needed. The self-floating series can be applied in full range of conditions. Especially the carbon fiber pontoons, it is light weight and strong buoyancy that is widely used in the vertical wells of small mud weight (can be as less as 1.0), which resolves the contradiction between inclination and mud weight when drilling in oil and gas wells of small formation pressure.
