Abstract

fetched live from OpenAlex

Abstract In oil recovery operations, microscopic displacement efficiency is dominated by capillary and viscous forces, which in turn determined trapping of oil or other fluids in a porous medium, whereas macroscopic sweep efficiency is controlled by mobility ratio and rock formation heterogeneity. This article addresses the use of the centric scan SPRITE magnetic resonance imaging (MRI) technique to visualize phase trapping and mobilization through a channel in a model unconsolidated porous medium. It also deals with the MR imaging of the effect of the application of a weak polyacrylamide gel through a high-permeability channel as in situ permeability-reduction treatment to control displacing fluid channeling.

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.
