New insights into the Kingia Sandstone facies distribution, and implications for hydrocarbon prospectivity, north Perth Basin, Western Australia
Bibliographic record
Abstract
The Kingia Sandstone has proven to be a prolific play fairway within the north Perth Basin, with primary porosity preservation observed down to at least 4600 mSS. However, the distribution of the Early Permian depositional and diagenetic facies has remained enigmatic. This is especially true given recent exploration results. Recent wells targeting the Kingia Sandstone have highlighted facies variability. As such, an opportunity exists to leverage legacy well data to investigate the interplay between sediment supply and accommodation space, resulting in improved reservoir characterisation. Through the integration of well logs, core and petrography studies, new insights into the spatial and temporal trends governing the presence and effectiveness of the Kingia are proposed. Implications of this work include Kingia Sandstone facies models that may be extended beyond known well control to help reduce subsurface uncertainty.

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.
