  Convective heat transfer in centrifugal pumps lifted wells: the case of South-Eastern Europe waxy wells cite

  Bojan Martinovic, Marija Živković, Branko Grubač (2021)

  Electric submersible pumps (ESP) are applied in wells where additional energy is needed to ensure discharge of the fluid to the surface through the tubing. At the discharge side of the pump the fluid has bigger velocity, thus the pump induces a forced convection between the fluid and the tubing inner surface. Understanding of convective heat transfer in wellbores and analyses of influential parameters provides a possibility to optimise value of convective heat transfer coefficient in order to avoid ...

  Productivity improvement with use of beam gas compressor: pilot test in Southeastern Europe mature field cite

  Bojan Martinović, Dušan Danilović, Branko Grubač, Robert Fadiga (2022)

  Most of the wells in the oilfield Turija are operating with sucker rod pumps, where casing pressure at around 15 bar, and with marginal production rates. The high value of casing pressure indicates high pressure on the face of the formation and depends directly on well productivity. In addition, with increasing value of the casing pressure gas column in the annulus is moving the dynamic fluid level near pump intake and more gas is entering the pump, it results ...

  Phase and microstructural study of urinary stones cite

  Miljana Mirković, Anja Dosen, Suzana Erić, Predrag Vulić, Branko Matović, Aleksandra Rosić (2019)

  In this paper we present the phase and morphological characteristics of urinary stones from Serbian patients. The study included for the first time the determination of the phase composition and a statistical analysis of the presence of different types of urinary stones in both men and women in Serbia. The main goal of study was representation of collected data for the first time. For past three years, more than 600 samples were collected from Serbian patients. The phase composition ...

  Natalija Pavlović, Branko Petrović, Tomislav Šubaranović, Ivan Janković (2022)

  Formiranje geomehanički tabilnih unutrašnjih odlagališta otkrivke ima izuzetno značajnu ulogu pri projektovanju i planiranju razvoja površinskih kopova uglja sa aspekta preraspodele masa otkrivke, dinamike eksploatacije, ekoloških zahteva, rudarskih rizika i troškova. Uvećanje zavodnjenosti unutrašnjeg odlagališta otkrivke površinskog kopa Tamnava-Zapadno Polje, kao posledica globalnih klimatskih promena sa pojavom katastrofalnih obimnih padavina i velike poplave, dovelo je i do značajnih ali i trajnih promena geomehaničkih karakteristika materijala, umanjenja stabilnosti generalne kosine unutrašnjeg odlagališta i znatnog povećanja rudarskog rizika. Inovirane varijantne ...

  The Fuzzy–AHP Synthesis Model for Energy Security Assessment of the Serbian Natural Gas Sector cite

  Aleksandar R. Madžarević, Dejan D. Ivezić, Miloš L. Tanasijević, Marija A. Živković (2020)

  Natural gas is used for the production of almost 20% of total energy today. The natural gas security of the Republic of Serbia is an urgent strategic, political and security issue. Serbia is one of the most vulnerable countries in Southeast Europe, because it only has one supply route. This study is a contribution to efforts to better understand the factors affecting energy security through the implementation of a new methodology based on the fuzzy–AHP synthesis model for measuring ...
