Formulation and characterization of surfactants with antibacterial and corrosion-inhibiting properties for enhancing shale gas drainage and production

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Jan. 18, 2025

A Gemini cationic surfactant was synthesized through an aldehyde-amine condensation reaction to address challenges related bacterial corrosion and foaming during shale gas extraction. This treatment agent exhibits sterilization, mitigation, properties. The mechanism of action characterized tests measuring surface tension, particle size, sterilization efficacy, mitigation efficiency, behavior. Results from the tension test indicate that at 60 °C, surfactants with a low carbon chain structure achieve lowest 32.61 mN/m critical micelle concentration. Particle size distribution (PSD) reveal within 1-10 concentration range, three types can form aggregates self-assembly, PSD range 100-400 nm. Antibacterial performance demonstrate 0.12 mmol/L 20-60 °C achieves bactericidal rate exceeding 99%, maintained even after 24 h contact. effect is enhanced under acidic alkaline conditions. Corrosion show 50 reaches optimal value over 70%. Bubble evaluation results suggest 1 exhibiting resistance mineralization up 200 g/L. development this establishes foundation for effectively addressing issues wellbore fluid encountered in wells.

Published: June 1, 2024

This study delves into the comparative efficacy of YOLOv5 and YOLOv8 in corrosion segmentation tasks. We employed three unique datasets, comprising 4942, 5501, 6136 images, aiming to thoroughly evaluate models' adaptability robustness diverse scenarios. The assessment metrics included precision, recall, F1-score, mean average precision. Furthermore, graphical tests offered a visual perspective on capabilities each architecture. Our results highlight YOLOv8's superior speed accuracy across further corroborated by evaluations. These assessments were instrumental emphasizing proficiency handling complex corroded surfaces. However, largest dataset, both models encountered challenges, particularly with overlapping bounding boxes. notably lagged, struggling achieve performance standards set YOLOv8, especially irregular In conclusion, our findings underscore enhanced capabilities, establishing it as preferable choice for real-world detection research thus offers invaluable insights, poised redefine management strategies guide future explorations identification.

Data Modeling Techniques for Pipeline Integrity Assessment: A State-of-the-Art Survey

IEEE Transactions on Instrumentation and Measurement, Journal Year: 2023, Volume and Issue: 72, P. 1 - 17

Published: Jan. 1, 2023

Pipelines are economical and efficient modes of transporting oil gas. will inevitably confront various risk factors through their lifespan, which could lead to defects. Defects in pipelines can compromise the integrity pipeline systems may result catastrophic accidents. Thus, it is vital conduct assessment so that safe operation be ensured. Up present, widely used approaches for include defect characterization, growth rate prediction, failure pressure evaluation. Although theoretical developments methods have yielded fruitful achievements significantly benefit industry practices, there still a lack systematic review covering whole process from data collection model establishment assessment. Therefore, comprehensive conducted this paper on modeling perspective. Firstly, description required construct models presented, where obtained inspection measurements, monitoring sensors, testing experiments, etc. Then, different techniques applied reviewed, classified into physics-based models, data-driven multi-model fusion. Also, advantages limitations these discussed. Finally, possibility applying existing digital twin explored.
