Advances and challenges in oil and gas pipeline pigging technology: a comprehensive review.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
In the oil and gas industry, pipeline transportation is crucial for ensuring energy supply. However, problems such as internal deposits and corrosion in pipelines can undermine their safe, efficient, and stable operation. Pipeline pigging technology is essential for maintaining pipelines, but existing pigging technology faces challenges in dealing with complex deposition situations and ensuring cleaning effects while minimizing pipeline damage. To address these issues, this study comprehensively reviews pipeline pigging technology. It combines experimental research and numerical simulation methods. Through a series of experiments on bypass pigs under different pipeline environments and working conditions, key factors like bypass fraction, flow rate, and pressure that affect the pigging process were identified. The construction of various mathematical models for numerical simulation further explored the impacts of factors such as bypass diameter, fluid properties, and pipeline geometry on the flow behavior, cleaning efficiency, and dynamic speed of the pig. This paper offers a comprehensive resource for the design, selection, and optimization of pipeline pigs. It also advances the development of pipeline pigging technology, which is of great significance for ensuring the safe and efficient operation of oil and gas pipelines.
