Initial 3-C–2D surface seismic and walkaway VSP results from the 2015 Brooks SuperCable experiment
Bibliographic record
Abstract
A 3C walkaway VSP and surface seismic experiment was conducted at the Containment and Monitoring Institute (CaMI) Field Research Station (FRS) in May of 2015. The FRS is located near the town of Brooks in southern Alberta, Canada. Multiple objectives for the program included student training, surface source and receiver comparisons, multi-component walkaway VSP acquisition, and velocity tomography for site characterization. Two parallel NE-SW receiver lines were laid out with one line centered on a well and the other offset 100 m to the northwest. Both receiver lines had single-component geophones at a 10 m receiver spacing. In addition, the line centered on the well had three-component geophones at a 30 m receiver spacing. A tool with three-component geophones was deployed within the well at three different levels, giving receiver positions from 106 to 496 m depth at a 15 m spacing. Two source lines centered on the well location, one linear with a vibe point (VP) every 10 m and the other semi-circular with a VP every 5 degrees were acquired three times, once for each tool position in the well. The source was an IVI EnviroVibe using a variety of filtered and unfiltered maximal length sequence pilots (m-sequences) as well as a linear 10-200 Hz sweep. This abstract presents a first look at the data and some early results. Presentation Date: Wednesday, October 19, 2016 Start Time: 4:25:00 PM Location: 163/165 Presentation Type: ORAL

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
