Sedimentology, sequence stratigraphy, and reservoir quality of the Lower Cretaceous Glauconitic Sandstone, southeastern Alberta
Bibliographic record
Abstract
The Lower Cretaceous (Albian) Glauconitic Sandstone is the lowermost stratigraphic unit of the Upper Mannville interval in southern Alberta. It overlies calcareous and fossiliferous strata of the Ostracode Limestone and is unconformably overlain by feldspathic and lithic-rich fluvial sandstone of the undifferentiated Upper Mannville. In the study area, Glauconitic Sandstone strata comprise three facies associations consisting of prograding shoreface to shallow shelf (FA1I), upper estuary channel fill (FA2) and tidally-influenced abandoned channel fill/interchannel (FA3) deposits. The Jenner Upper Mannville E Pool is a 10 km long by 2 km wide north-south trending conventional oil pool located in Townships 19--20, Range 9W4 in southeastern Alberta. Since its discovery in 1963, the pool has produced 7.3 million barrels of 21.1° API oil and 6.7 billion cubic feet of gas from the Glauconitic Sandstone. The original oil in place is 28.6 mmbbl and estimated remaining reserves are of the order of 700 mbbl.

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.
