Abstract

fetched live from OpenAlex

Heavy oil becomes more interest owing to oil prices and the huge amount of reserves. Steam injection is a common method for heavy-oil production with emulsion formation. Also carbon dioxide injection is applied for viscosity and interfacial tension reduction. CO2 becomes more important because of environmental concerns. CO2 storage in reservoirs like depleted oil wells becomes widespread. Hence, understanding the behavior of CO2 when it encounters emulsive heavy-oil is critical. In this work, the interfacial tension and oil-swelling factors of CO2 in oil and its emulsions are measured at 296 K and pressure from 0.5 to 1.5 MPa with water/oil ratio from 0.00 to 12.27 percent compared to original oil. The results show that the interfacial tension decreases at higher pressure ranging from 3.7 to 16.8 percent and water content from 10.3 to 22.6 percent. Furthermore, oil-swelling factors increase with pressure and water content up to 1.9 percent and 8.0 percent, respectively. These results are explained by absorption processes in that high pressure can serve as high driving force for CO2 solubility.

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.
