Gyro Compassing All-Attitude Tool
Gyrodata’s new GCAAT combines purpose built sensors, a new mechanization and advanced processing. Compared to IFR corrected MWD surveys GCAAT is 200% more precise.


Innovation

GCAAT (Gyro Compassing All-Attitude Tool) combines purpose built sensors, a new mechanization and advanced processing enabling accurate surveying to horizontal and beyond. An additional benefit of the new mechanization is the virtual elimination of the notorious East/West no-go zone. Initially developed for use in the GWD90™ system, the instrument can now be deployed as a drop survey tool.

GCAAT graphFeatures
 - The tool can be dropped and pumped down to land in the BHA on any planned trip out of hole.
 - Survey data is recorded to memory at each connection.
 - BHA sag and Multi-station corrections are applied at the rig site.
 - Immediate comparison to previous surveys will detect possible gross errors.
 - Reduced uncertainty and increased safety factors as drilling progresses.
 - Closer approach to other wells is possible and better positioning in the reservoir results.
 - New mechanization eliminates East/West no-go zone.


Benefits
 - Double the accuracy of IFR corrected MWD
 - Gross error detection
 - No degradation of accuracy in East/West directions
 - Each survey is independent resulting in no propagation of errors
 - Robust QC
 - Definitive survey generated as drilling progresses
 - Complete survey/re-survey of entire wellbore on each deployment
 - Little or no rig time used to record a highly accurate survey
