Abstract

fetched live from OpenAlex

The spatial-vector-based stochastic modeling of point-bar reservoir architectures is proposed in this paper.Compared with traditional object-based modeling approaches,this proposed modeling approach has no cell or grid definition at the simulation stage.Architecture elements are simulated directly by dropping them into the modeling domain.Borrowing the idea from the vector image format in computer graphics,we used spatial lines,points and surfaces to form simulated architecture element bodies.The architecture elements are defined with spatial vectors which are expressed using their spatial distribution parameters.And the shape parameters are in real data set.Thus,different scale of heterogeneities can be reproduced from the realization.Because the well data conditioning is obtained through the modification of the architecture elements' spatial locations and their shape parameters,it is easier to be satisfied.And the simulation has a faster convergent speed compared with traditional object-based approaches because of grid free and parameter adjustment in simulation.A developed block of one oilfield in eastern China,which has a geological background of meandering-river point-bar sand,is used to illustrate the theory and modeling procedures of this approach.

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.
