Abstract

fetched live from OpenAlex

Interferometric Synthetic Aperture Radar (InSAR) is a satellite-based technology that measures minute changes of surface elevation through time. These deformation changes, often less than 1 mm/month, may be caused by changes in the subsurface (e.g., imbalance between fluid withdrawal and injection, collapse of underground mines), or changes at the ground surface (e.g., surface blisters caused by shallow injection of steam or out-of-zone fluid movement, slope failures). Radar waves from successive passes of polar-orbiting satellites provide trillions of 3m by 3m pixels worldwide on a daily to monthly frequency. Using cloud computing and interferometry, the pixels over areas of interest can be used to monitor activities within oil and gas reservoirs, and also to give warnings of possible problems developing at the surface. Examples are shown for the Belridge giant oil field (California), Groningen giant gas field (the Netherlands), and the Peace River area (Alberta). In the three cases, surface deformation is used to monitor areal conformance in the reservoirs. Also, having satellite passes every 11 days means that reservoirs can be monitored proactively and the resultant datasets have the potential to replace traditional 4D seismic at a cost that is significantly less.

Full frame distilled prediction

Teacher imitation

Not 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.
