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

This study aims to develop an efficient and environmentally friendly approach for the resource recovery and harmless treatment of waste oil-based drilling mud (WOM). A comprehensive treatment process was implemented, including chemical demulsification and mechanical dehydration of WOM, advanced oxidation and coagulation-flocculation treatment of intermediate water (IW), and cement-based solidification of dehydrated mud (DM). The results demonstrate that the dehydration process achieved excellent oil recovery (95.62%) and volume reduction (93.20%), with residual oil and water contents of 0.40% and 4.33% in DM, respectively. The IW treatment (pH adjustment to 6, 5000 mg/L NaClO oxidation for 25 min, followed by pH 9 adjustment and sequential addition of 120 mg/L PAC and 8 mg/L APAM) produced clean water (CW) with 98.6% transmittance (TR), suitable for fracturing fluid preparation. Furthermore, DM solidified with fly ash: cement: quicklime (10%:30%:20%) exhibited high compressive strength (16.22 MPa) and leachate meeting national discharge standards. This integrated approach successfully transforms hazardous WOM into reusable resources while ensuring environmental compliance, providing a practical solution for sustainable drilling waste management.
