Abstract

fetched live from OpenAlex

Summary Drilling fluid containing colloidal gas aphron (CGA) microbubbles can bridge the pores of the reservoir rock in the near-wellbore region and reduce the risks of lost circulation and formation damage. The advantage of using CGA systems is that the CGAs can be removed easily during the initial stages of production, thereby reducing the costs associated with stimulation processes such as acidizing. Although there has been some work performed on the flow of the microbubbles through porous media, little is known about the optimal conditions for blocking the pores. Specifically, the effect of the interaction between microbubbles and reservoir fluid on the microbubble stability and pore-blocking ability has not been determined. This study is focused on determining effects of CGA composition on the resistance to the flow of microbubbles through porous media. Increasing resistance to fluid flow was observed as more CGA fluid was injected, indicating that microbubbles could effectively block the pores. Effects of water, brine, mineral oil, and crude oil, as saturating fluids, on the microbubble stability and pore-blocking ability were also investigated.

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.
