Regional Overview With New Insights Into the Petroleum Prospectivity of the Southeastern Offshore Newfoundland Margin, Canada
Bibliographic record
Abstract
Summary The Carson, Bonnition and Salar Basins offshore Newfoundland and Labrador, Canada comprise and area of approximate 150,000 km2 situated southeast of the oil prolific Jeanne d’Arc Basin. Previous exploration rounds in the 1970s and 1980s were unsuccessful at discovering hydrocarbons in the basins; however, renewed exploration efforts are ongoing in the region with recent 3D seismic acquisition, an exploration license acquired in 2015 and a land sale scheduled for 2019. Recent 2D seismic acquisition by TGS and PGS, as well as fluid inclusion studies, updated biostratigraphic reports and multibeam and seabed coring programs have enhanced our understanding of the region. This area is a branch of the North Atlantic Mesozoic rift network which experienced two main periods of rifting – Late Triassic to Mid Jurassic and subsequent reactivation in the Late Jurassic-Early Cretaceous. The multiple rift phases and salt diapirism have led to multiple structural, stratigraphic and combination play types. The Kimmeridgian has not been encountered in this region and is an unproven source rock. Other potential source rocks include Middle Jurassic, and Cenomanian-Turonian as seen at the ODP 1276. The regional studies and recent 2D seismic data are providing positive indications of an active petroleum system in the region.

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.
