Detecting bypassed pay from 3D seismic data using a facies-based Bayesian seismic inversion, Forties Field, UKCS
Bibliographic record
Abstract
The Forties Field, UKCS, is the largest oil field in the UK sector of the North Sea with an estimated STOOIP between 4.2 and 5 billion barrels. Discovered in 1970 by BP, the field was brought online in 1975. In 2003 Apache Corp acquired the Forties field from BP and quickly pursued a program of 4D seismic interpretation to assist in field remediation. After some 40 years of production the field continues to produce at daily production rates exceeding c. 45K bopd. In this paper we present the results of a new inversion technology applied to the Forties field to assist in the detection of direct hydrocarbon indicators and remaining reserves from two vintages of 3D seismic.

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.
