HDS-1G™ Directional MWD Service

Magnetic Interference Free MWD & Gamma Ray

The Gravity MWD® system is a magnetic interference free survey technique. The Gravity MWD® system uses the modular HDS-1GTM tool where magnetic interference prevents the use of conventional MWD tools. The system is highly insensitive to down hole movement during survey allowing operation in environments where gyro surveying can be problematic.

Applications for the Gravity MWD® system are:

• Casing drilling
• Drill out of casing shoes/casing windows
• Re-entry work
• Geo-thermal wells with high magnetism
• Relief wells
• Anti-collision
• Multi-laterals
• For use in conjunction with WINNER™ passive ranging
