ABSTRACT: Sequence Stratigraphy and Reservoir Quality of Alluvial/Lacustrine Reservoirs in the Albert Formation, Horton Group (Mississippian), Moncton Basin, New Brunswick, Canada
Bibliographic record
Abstract
Sequence stratigraphy has proved to be a powerful approach to the modeling of stratal successions in increasingly diverse types of sedimentary basin, including lacustrine basins. New core data from a drilling program in the Moncton Basin of eastern Canada provides an opportunity to apply a sequence stratigraphy to the Mississippian Horton Group, specifically the alluvial-lacustrine Albert Formation. A low resolution tectonic sequence is attributable to basin initiation (basal conglomerates Dawson Settlement Member), deepening (sediment starvation - mudstone and oil shale of the Frederick Brook Member), and final infilling (mixed sandstone and mudstone - Hiram Brook Member). Lithofacies interpretations from core, and geophysical evidence further indicates that the higher resolution sequences would have formed under the influence of a predominantly wet climate. Accordingly, architectures typical of overfilled or Newark type basins are identified, such as well-preserved high-relief lacustrine deltas. Lithofacies successions also suggest that interbasinal thresholds also may have influenced architecture. Advances in SEM and image-analysis technology are also providing more quantitative porosity and cement data for samples from the new core, and confirm existing diagenetic models.

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.
