A clean self-diverting acid for carbonate reservoir in deep wells at high temperatures and its performance evaluation.

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
The key technology for stimulating carbonate oil and gas reservoirs lies in the meticulous selection of an appropriate acid system, control over the action distance of active acid on the reservoir, and attainment of good conductivity through non-uniform etching of the rock wall surface by acid. Currently, retarded acid systems are beset by serious acid filtration problems, resulting in a limited length of acid-etched fractures and incomplete polymer breakage of glue in residual acids after stimulation, ultimately impeding oil and gas reservoir production and efficiency. In response to the development requirements of high-temperature deep hydrocarbon reservoirs, a clean diverting acid system based on VES surfactant has been successfully developed. Through systematic evaluation of key parameters including temperature-viscosity characteristics, filtration performance, retardation efficiency, friction reduction capability, and intelligent viscosity-altering mechanism, experimental results demonstrate: Under conditions of 170 s
