Inside METC

METC Catalogue - MWD & LWD SYSTEM

 

High accuracy measurement of inclination & azimuth and tool face for directional drilling operations. 

Great reliability in extremely high shock and vibration environment. 

Temperature compensated to 150°C. (175°C option) 

Bottom mounted retrievable. (Top rotary pulser option) 

Positive mud pulse system. 

Delicate design for easy transport, set-up and operation, simplified maintenance.
