Reservoir characterization of the Flag Sandstone, Barrow Sub-basin, using an integrated, multiparameter seismic AVO inversion technique
Bibliographic record
Abstract
A series of oil and gas fields have been discovered since 1979 in the Early Cretaceous Flag Sandstone in the Barrow Sub-basin of Western Australia's Carnarvon Basin. The Flag Sandstone is a lowstand complex of gravity flow sandstones deposited beyond the shelf edge of the Barrow delta. Figure 1 shows a stratigraphic chart. The permeable Flag Sandstone forms a consistent, high-quality reservoir that is capped by the impermeable Muderong shale. In the area immediately adjacent to and south of Varanus Island, the main trapping mechanism is four-way dip-closed anticlines, formed by drape compaction. Structural closure alone does not appear sufficient for oil emplacement as a limited number of prominent closed structures have been drilled and found water-wet. The known oil fields are nearing depletion and the goal is to properly locate additional wells to ensure complete development of the area.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
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.
