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

Crude oil production has been enhanced using microbial-enhanced oil recovery (MEOR) in many oilfields. After over six years of MEOR test and field application in high-salt environments and unconventional oil reservoirs of plateau oilfields, MEOR mechanisms of emulsification, surface tension reduction, petroleum degradation, and reservoir microbial community structure adjustment were developed. Based on the core MEOR mechanisms of microbes, we carried out paraffin wax removal, single-well huff-puff, and microbial flooding in the Qinghai oilfield, thereby increasing oil production and sustaining economic benefits. These results demonstrate that microorganisms can be enhanced and applied in oilfields with large temperature differences, high salinity, and unconventional reservoirs.
