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.

Hidrogeotermalni resursi teritorije grada Beograda
Ana Vranješ (2012-12-12)Republika Srbija je izrazito bogata hidrogeotermalnim resursima. Podzemne vode satemperaturama preko 20oC (pa do 96oC, Vranjska Banja) relativno su dobro iskorišćene.Nasuprot njima, podzemne vode sa temperaturama do 20oC do sada uglavnom nisu bilepredmet istraživanja sa bilo kog aspekta izuzev za potrebe vodosnabdevanja.

Analiza rada električnih centrifugalnih pumpi
Milica Stanojević (2024)Ovaj rad analizira rad električne centrifugalne pumpe (ESP) u naftnoj industriji, sa fokusom na problem taloženja kamenca (karbonatnih naslaga) unutar sistema. Električne centrifugalne pumpe (ESP) predstavljaju srce mnogih naftnih bušotina. Njihova visoka pouzdanost i sposobnost rada u zahtevnim uslovima čine ih neophodnim za stabilnu i kontinuiranu proizvodnju.Senzori igraju ključnu ulogu u praćenju rada ESP sistema i detekciji ranih znakova taloženja kamenca. Problem taloženja kamenca je izuzetno značajan, jer može dovesti do smanjenja efikasnosti pumpe, povećanja troškova održavanja, i dugoročnih zastoja ......

Laboratory testing of fly ash
Fly ash is one of the most common waste materials created by burning of coal. It is composed of smaller particles, consisting mainly of aluminosilicate glass, mullite and quartz, which are collected by electrostatic separators (filter) of gaseous products arising from the combustion of coal.

Properties of fly ash and slag from the power plants
This paper describes the physical, chemical and mineral properties of ash and slag, which were taken from thermal power plants Nikola Tesla A, Nikola Tesla B, Kostolac A and Kostolac B. The knowledge of the mineralogical material composition is important because the type of minerals directly determines the properties of the fly ash and slag and their possible application. Laboratory tests showed that ash and slag samples consist of the following minerals: amorphous materials, quartz, feldspar, mullite, melilite, cristobalite, ...fly ash, slag, physical composition, chemical composition, mineral composition, X-ray diffraction method...
