Data Reliability:
How to assess and improve their representativity?
Before/After Post-processing
The cross-referencing data methodology allows us to get rid of the time factor, and to analyze the variations of a single parameter. This process highlights hidden information for a better understanding of the construction.
Post-processing :
Error diagnosis and correction.
Using cross-referencing data methodology.
Analysis of the correlation between parameters.
Comparison targets:
Error detection in topographic measurements based on the adjustable target.
WIP
The adjustable target is placed at the desired distance from the initial target. During the topographic survey, the second target is also measured. The measurement between the two targets will be compared to the preset distance to (in)validate the rest of the survey.
Knowing the drill pipe orientation is crucial for a sound data analysis, especially for inclinometer monitoring. Indeed, this method is based on the pipe verticality, which is theoretical and needs to be confirmed.
WIP
Rotativity:
Verification of the initial rotation of an inclinometer drill pipe to confirm its actual orientation whatever its depth.
