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
