Geo-Guide ALC
Gyrodata’s Advanced Logging Combination System is a major breakthrough in wellbore surveying instrumentation, providing operators with cost savings, a highly accurate wellbore delineation and enhanced positioning within the reservoir.


- Logging combinations are now possible in horizontal cased and open holes.
- Deployed using wireline, pipe conveyance or downhole tractors.
- Simultaneous data transmission.
- 22 Hz data sampling.
- Measures exact wireline cable stretch.
 - Logging speeds are dependent upon the main logging tool.
 - 150 Deg C. rating for unlimited time.
 - 250 Deg C. high temperature option.


Design / Operation

A 3 3/8″ OD logging tool housing has been modified to contain a specially designed rate continuous gyro logging system cartridge, which enables simultaneous operation and data transmission with virtually all currently available open and cased hole logging tools.


Advantages / Benefits
 - Substantial rig time savings.
 - Better well placement within the reservoir.
 - Orientation of imaging tools.
 - Elimination of depth uncertainty between LWD, Wireline Logs and Gyro Surveys.
 - Improved positional accuracy.
 - Improved alonghole depth accuracy.
 - Very high resolution log provides exact wellbore profiling.
 - Orientation of wireline orientated perforating tools.
 - Highly accurate definitive true vertical depth versus gamma ray log for the well.
 - Identifies wellbore tortuosity, porpoising and micro doglegs.
