Processing of DAS and geophone VSP data from the CaMI Field Research Station
Bibliographic record
Abstract
The monitoring program of CO2 injection at the Field Research Station in Newell County Alberta includes diverse surveys and new technologies. The acquisition and processing of Vertical Seismic Profiles (VSP) were undertaken for this thesis. More specifically, the analysis of three different surveys: a walk around VSP for azimuthal anisotropy analysis, zero offset VSPs to test the emerging DAS technology and walk-away VSP to obtain imaging results for straight and helical wounded fibre optic cables. From the azimuthal analysis, the fast direction was identified to the northeast with an epsilon value (0.02) indicative of weak anisotropy. For the DAS VSP processing, a calibration step was necessary to register the precise depth of DAS traces; two approaches were completed and yielded similar results. Additionally, DAS strain rate measurements were converted to strain to compare it with geophone data. The excellent correlation between the 3D seismic lines and VSP-CDP stacks and the imaging results shows that DAS is a promising technology for subsurface imaging and monitoring.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
