Abstract
The Terra Nova field is located in the Jeanne d’Arc basin, approximately 300 km east-southeast of St. John’s, Newfoundland. The Terra Nova field is very complex, both structurally and stratigrapically. The production strategy is pressure support by water and gas injection. Knowledge and understanding of the location of faults and flow barriers, baffles, and flow communication paths are important information to manage the reservoir. Fault transmissibility was found to be the most important parameter for achieving history matching. Modelling showed that small 4D amplitude and timeshift effects were expected. Conventional 3D marine time-lapse data was acquired over the field after about 5.5 years of production. Statoil’s proprietary method for deriving timeshifts was used to align the base and monitor stacks in time. Interpretation of the time lapse data showed that significant time shifts in the order of 0.2-1 ms could be detected due to pressure changes in the reservoir. Interpretation of the timeshifts togheter with changes in amplitudes were used to make tentative interpretation of relative fault transmissibility and location of pressure barriers or baffles in the field.

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 it
