Containment and Monitoring Institute - Baseline Geophysics for CO2 Monitoring with Crosswell Seismic and Electromagnetics
Bibliographic record
Abstract
The Containment and Monitoring Institute (CaMI) has built a Field Research Station (FRS) near Calgary, Alberta, Canada, designed around small injections (up to 1000 tonnes per year) of CO2 at depths of approximately 300 m and 500 m. Baseline borehole geophysical surveys have been completed at the CaMI site as part of a larger monitoring effort aimed at detecting and monitoring the small (1-2 ton) gas phase CO2 plume as well as any vertical migration. Crosswell seismic and EM data, as well as borehole-to-surface EM data, were recorded and have sufficient data quality to proceed with time-lapse monitoring. Initial processing for quality control has been accomplished. Seismic processing to date includes initial travel time picking and indicates that data is sufficient for velocity inversion. EM processing includes comparison of acquired data (amplitude and phase) with a layered model based on resistivity logs with repeatability of ~2%. The use of fiberglass casing in one monitoring well supports the use of EM methods. Joint inversion of the seismic and EM measurements (i.e. P-wave velocity and electrical conductivity) is planned to improve the estimate of CO2 saturation in the subsurface.

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.
