Опубликована: Янв. 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.

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, Год журнала: 2023, Номер 72, С. 1 - 17

Опубликована: Янв. 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. This aims provide guideline researchers select optimal according availability research requirements, community, as well as, industry.

Visualization and Analysis of Oil and Gas Pipeline Corrosion Research: A Bibliometric Data-Mining Approach

Journal of Pipeline Systems Engineering and Practice, Год журнала: 2024, Номер 15(3)

Опубликована: Март 22, 2024

The problem of corrosion in oil and gas pipelines is one the major factors affecting process safety efficient sustainability development industry. To gain a better understanding global research trends dynamics field pipeline to advance control technology, we conducted literature review using sample 1,745 papers from Web Science (WOS) database published 2002 2022. We employed bibliometric analysis approach investigate distribution publications over time, geographic regions, organizations, authors, journal cocitation, identify hotspots frontiers. results revealed an exponential growth overall number papers, with most rapid increase occurring last 4 years. China, US, Canada, United Kingdom, Brazil emerged as active countries natural research, Mexico, Australia also exhibited significant influence field. journals Engineering Failure Analysis, Corrosion, Corrosion had highest impact this domain. Notably, stood out influential highly regarded fundamental theories framework realm have been primarily established, large directions frontier branches are emerging. flow parameters on corrosion, reliability assessment, defects failures identified three main paths In terms methodologies, machine learning techniques becoming increasingly prevalent, growing studies adopting various methods. Among these methods, explainable deep at forefront corrosion.
