Gyro Multi-Shots

Gyro Multi-Shots

Gyro Multi-Shots (GMS) shall only be run in preference to EMMS to verify the surveys used to drill a hole section where magnetic interference may not be corrected. Gyro Multi-Shots are also used for ‘tying-in’ MWD surveys.

They are also used inside a driven conductor (where a Gyro Multi-Shots is required for tying-in shoe co-ordinates to the surface).

Gyro Multi-Shots surveys may be taken inside casing eg., 20in and 13.3/8in casing or occasionally in drill pipe or tubing.
