1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Middle-phase microemulsions (Winsor III) are critical for enhanced oil recovery (EOR) due to their ultralow interfacial tension (IFT) and high oil solubilization capacity. In this study, hydrophilic-lipophilic deviation (HLD) and net average curvature (NAC) theories were employed to design a salinity-optimized microemulsion system using coconut oil diethanolamide (6501) for a specific crude oil. Emulsification tests confirmed that increasing salinity expanded the middle-phase volume, while low salinity favored Winsor I (O/W) microemulsions. Polymer destabilized middle-phase formation but improved recovery by 40-45% due to enhanced sweep efficiency. Core flooding revealed that traditional surfactant-polymer (SP) flooding outperformed salinity-tuned microemulsions, likely due to insufficient oil-surfactant mixing after water flooding. Results of this work provide a framework for optimizing microemulsion-based EOR processes through integrated theoretical and experimental approaches and offer potential optimization strategies for field-scale application.
