Structural and Stratigraphic Interpretation of a Frontier Exploration Region, Offshore Labrador, Canada
Bibliographic record
Abstract
Summary The Chidley Basin is an unexplored sedimentary basin encompassing the shelf to deep water of the Labrador Sea. Over 33,000 line kms of long offset 2D seismic data has been acquired since 2011 and is revealing elements of the basin extent and geometry. The lack of wells in the basin requires a combination of detailed seismic interpretation, AVO rock physics work and seafloor coring to define the potential petroleum system. Immature Paleocene source intervals with high TOC have been encountered on the shelf and can be mapped into the slope and deep water. These could provide an actively generating source in a deeper burial setting. Undrilled synrift packages exist within the Chidley basin that could provide additional reservoir and source rock intervals. Regional AVO scoping work is helping to constrain the play fairways throughout the Paleogene section. The identified AVO anomalies are commonly associated with large structural closures within a listric fault system and overlying BSRs. These early insights are indicating that exploration potential in the slope and deepwater Labrador region is high.

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.
