Potential of the Orphan Basin, NL, Canada
Bibliographic record
Abstract
Summary The underexplored West Orphan Basin appears prospective for oil and gas, after new regional seismic data uncovered a large play trend in the Lower Tertiary sands, indicative of turbiditic fan complexes. The objective was to provide petroleum resource estimates for the area using seismic reservoir characterization, and 2D/3D basin modelling for play risk analysis and volume estimates. A seismic inversion and characterization was performed to discriminate sand probability. Some Tertiary and Cretaceous sands appear to have high porosity (∼30%) with a clear indication of the presence of hydrocarbons, most probably light oil. Regional sequence stratigraphy work coupled to a forward stratigraphic model (DionisosFlow™) helped to map the extension of reservoirs, carrier beds and seals. After calibration of the thermal and fluid flow regime temperature, maturity and pressure, an integrated 3D model was built using TemisFlow™ to estimate the oil and gas charge in the potential traps (stratigraphic and structural) in the various plays. The resource assessment of the Orphan area demonstrates a potentially prolific petroleum system. The uncertainty on HC volumes is given by the distribution of unrisked volumes in place. The range varies from 12.9 BOE to 45 BOE. The Probability of Geological Success is estimated to 16%.

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.
