Abstract

fetched live from OpenAlex

Carbon dioxide injection, with the development of carbon dioxide capture technology, is regarded as a promising method for enhanced oil recovery (EOR). Miscible flooding of carbon dioxide EOR theoretically provides a high recovery factor. However, there exists a minimum pressure requirement to achieve miscible flooding, which is minimal miscible pressure (MMP). The study in this paper investigates the carbon dioxide flooding based on simulation. The feasibility of reducing minimal miscible pressure by enriching the injected carbon dioxide is first analyzed through phase behavior simulation. Then, a carbon dioxide flooding test has been simulated and compared with real laboratory data. The sensitive parameters in carbon dioxide flooding were ranked in sensitivity analysis and updated through inverse history matching. The updated relative permeability curves not only reflect a residual oil saturation reduction due to the carbon dioxide interacting with a fluid but also reduce the uncertainty of measurement in laboratory tests.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
