Product Introduction

his 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 wide range of conditions. Especially the carbon fiber pontoons, light weight and strong buoyancy, are widely used in the vertical wells of small mud specific gravity (can be as less as 1.0), which resolves the resolve contradiction between survey and mud weight when drilling small formation pressure oil and gas wells.

Features

►Electronic single shot survey instrument, no winch is needed.

►Descending or floating up depending on mud circulation

►Providing well attitude parameters.

►Applicable condition specific gravity of mud is among 0.8 to 2.0g/cm³( 0.03~0.07 lb./in³), inclination< 40°

Application

►Supervise the well trajectory in oil drilling engineering.
