Effects of Oil Viscosity and Interfacial Reaction on the Displacement of Oil from Porous Media
Bibliographic record
Abstract
Displacement of oil from unconsolidated porous media was investigated. Waterflooding and alkaline flooding tests were conducted in model porous media consisting of fine glass beads wet-packed into a cylindrical holder. Mixtures of light and heavy paraffin oil of viscosity ranging from 20 to 70 mPa s were used as the oil phase. Acidic oil was simulated by dissolving 10 mmol/l of linoleic acid in the oil. As expected, recovery of neutral oil by waterflooding decreased as oil viscosity increased. Addition of acid to the oil reduced the waterflooding recovery by more than 20% for all oils. Alkaline flooding of after-waterflood residual oil produced incremental recovery only in the case of the least viscous oil (20 mPa s). The incremental recovery increased with the concentration of alkali only up to 25 mmol/l and remained constant thereafter.

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.
