Metagenomic Analysis and Core Flooding Reveals the Indigenous Bacterial Community Information and MEOR Potential of the Main Water-Drive Low-Permeability Reservoir in the Ordos Basin.

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.
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
Oil recovery decreased with prolonged waterflood development in the main reservoirs in the Ordos Basin, and the extraction of the remaining oil was gradually difficult. To exploit oil-producing potential through microbial enhanced oil recovery (MEOR), bacterial communities of 26 samples from Yan 9, 10 layers, and 15 samples from Chang 6 layers were analyzed based on high-throughput sequencing. 1578 and 3581 amplicon sequence variants were obtained from Jurassic and Triassic samples, and α diversity analysis showed that dominant bacterial genera existed distinctly in both study areas. The distribution of the Jurassic bacteria community differed from that of the Triassic, revealed by a principal coordinate analysis.
