Abstract

fetched live from OpenAlex

Strategic and operational management in the exploration and production business is characterised by prediction and decision making in a data-rich, high-uncertainty environment. Analysis of predictive performance since the 1970s by multiple researchers indicates that predictions are subject to over-confidence and optimism negatively impacting performance. The situation is the same for other areas of human endeavour also operating within data-rich, high-uncertainty environments. Research in the fields of psychology and neuroscience indicates the way in which the human brain perceives, integrates and allocates significance to data is the cause. Significant effort has been dedicated to improving the quality of predictions. Many individual companies review their predictive performance during long periods, but few share their data or analysis with the industry at large. Data that is shared is generally presented at a high level, reducing transparency and making it difficult to link the analysis to the geology and data from which predictions are derived. This extended abstract presents an analysis of predictive performance from the Eromanga Basin where pre-drill predictions and detailed production data during a period of decades is available in the public domain, providing an opportunity to test the veracity of past observations and conclusions. Analysis of the dataset indicates that predictions made using both deterministic and probabilistic methodologies have been characterised by over-confidence and optimism. The reasons for this performance are discussed and suggestions for improving predictive capability provided.

Full frame distilled prediction

Teacher imitation

Not 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.
