BSR Distribution from Newly Acquired 2D Seismic and the Potential Link to Thermogenic Petroleum Systems, Offshore Newfoundland and Labrador, Canada
Bibliographic record
Abstract
Summary Newly acquired 2D broadband seismic data has led to new data coverage over the slope and deep water regions of the margin. In other petroleum exploration regions there are several examples of attempts to link active thermogenic petroleum systems to the occurrence of bottom simulating reflectors. Given the recent increase in seismic data coverage and ongoing seabed sampling programs, are there new observations derived from this dataset that can lend support to the previous efforts undertaken along the Eastern Canadian margin? Four cases of mapped BSR’s are highlighted in this study, with emphasis on relating the newly acquired seismic data to observations from previous studies. Some BSR’s exist near mapped AVO anomalies with associated faults, potentially feeding the gas hydrates from depth. At the Mizzen oil discovery, the BSR in that region may be related to migration of hydrocarbon from a proven thermogenic petroleum system. Conclusions of previous studies assessed some thermogenic hydrocarbon input to the hydrate and implied charge from depth. Heat flow measurements associated with the seabed coring program also support higher gradients in the slope to deepwater areas. This would support the addition of thermogenically derived C2+ gases in order to explain the hydrate stability depth observed.

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.
