Mitigating hydrate formation in onshore gas wells: A case study on optimization techniques and prevention
Gas wells, particularly those situated onshore, play a vital role in the global energy sector by supplying a significant portion of natural gas. However, operational challenges, notably gas hydrate formation, pose substantial issues, leading to complications such as flowline blockages and unexpected well shutdowns. Gas hydrates, crystalline structures resembling ice, ...Gas Well, Gas Hydrate Formation, Well Modeling, Well Performance Optimization, Choke Position Adjustments, Methanol InjectionMilica Ješić, Bojan Martinović, Stefan Stančić, Miroslav Crnogorac, Dušan Danilović.

Eigensensitivity and structural optimization with accent on the repeated frequencies
Sensitivity analysis is the study of changes in system response with respect to design parameters. It is being used in a variety of engineering disciplines ranging from automatic control theory to the analysis of large-scale physiological systems. Some of areas where sensitivity analysis has been applied include: development of insensitive control systems, use in gradient based mathematical programming methods and approximation of system response to change in a system parameter, assessment of design changes on system performance. Eigensensitivity analysis ...Nataša Trišović, Wei Li, Nikola Mladenović, Olivera Jeremić, Ines Grozdanović, Ana Petrović.

Probabilistic analysis of anisotropic rock slope with reinforcement measures
During the construction of E75 highway through Grdelica gorge in Serbia, a major failure occurred in the zone of reinforced rock slope. Excavation was performed in highly anisotropic Paleozoic schist rock formation. The reinforcement consisted of the two rows of micropile wall with pre-stressed anchors. Forces in anchors were monitored with load cells while benchmarks were installed for superficial displacement measurements. The aim of the study is to investigate possible causes of instability considering different probability distributions of the ...Zoran Berisavljević, Dušan Berisavljević, Miloš Marjanović, Svetlana Melentijević.
