Одређивање резерви нафтног лежишта „Х“ методом материјал баланса
Александра Петровић (2024)Метода материјалног баланса је кључна техника у процени резерви нафте и гаса у лежиштима која омогућава системско прорачунавање доступних резерви. Циљ ове методе је да се прецизно израчунају количине флуида у лежишту на основу доступних PVT података, података о лежишту и производњи. Резултати примене методе материјалног баланса показују да је она ефикасна у пружању кавнтитативних процена, међутим њена тачност зависи од квалитета улазних података. Метода материјалног баланса пружа основу за процену резерви, али може бити подложна грешкама због непрецизности ...... je: W — IIlouerHa 3anpeMuHa Bo/nte y nexumrry, [m*] W — ykynHo npoH3Be/teHa KojiHuHHa Bonne, [m?| B, — 3anpeMuiHHcku KkoeQuuujeHr Bojte, [mž?/m*] W.B — IHpouaaBeAteHa KojtuBHa BoAte y pacnoHy naja npaHcKa, [m*] W. — KojmunHa yroka Bone, [m*] 3artpeMuHa 5 Hacraje imipekbeM raca H3 racHe KaTIc ...

Geotechnical zoning of the terrain along the first section of E-80 highway in Serbia – SEETO route 7
Part of E-80 highway that passes through Serbia (from the city of Nis to the administrative border Merdare) is 77 km long. The highway is divided into two sections: the first from Nis to Plocnik (39.4 km long) and the second from Plocnik to the administrative border with Kosovo. The route is designed through a typical plain and hilly terrain in which different geological units are dominant: crystalline schists, neogene sediments of foothills and quaternary sediments in the valley ...... terraced plateaus (al, al-pr, pr, t1, t2) Quaternary and Neogene hilly terrains (dl-pr, dl, Pl, M-Pl, M) Cretaceous flysch complex (pr, K) Neogene hilly terrains (Pl, M-Pl, M) are usually covered with Quaternary sediments (dl- pr, el-dl, pr).

Верификација етажних транспортера на угљеном систему – површински коп Дрмно
Тамара Андрејевић (2024)У савременом рударству, површински копови угља наилазе на различите проблеме које треба превазићи зарад добијања потребне количине угља. Као највећи потрошачи овог енергента јављају се термоелектране, где на основу овога можемо да закључимо колико су блиско повезани добра и континуирана производња на површинском копу и рад термоелектрана. Са циљем да се обезбеди стабилна и континуирана производња, потребно је да се направи добар одабир транспортера.

Dehydroicetexanes in sediments and crude oils: Possible markers for Cupressoideae
Hans Peter Nytoft, Geir Kildahl-Andersen, Sofie Lindström, Frode Rise, Achim Bechtel, Danica Mitrović, Nataša Đoković, Dragana Životić, Ksenija A. Stojanović (2019)Two previously unidentified dehydroabietane isomers were isolated from Miocene Serbian lignite and Rhaetian (Late Triassic) coaly mudstones from South Sweden and characterized using NMRspectroscopy as cis- and trans-dehydroicetexane. Both have a 9(10?20)-abeo-abietane or icetexane skeleton, consisting of a 6-7-6 tricyclic framework with seven carbons in ring B instead of the usual six in common diterpanes of the abietane-type. Dehydroicetexanes can be detected using GC-MS-MS in m/z 270?146 chromatograms without interference from dehydroabietane or other isomers. Dehydroicetexanes are often abundant ...Hans Peter Nytoft, Geir Kildahl-Andersen, Sofie Lindström, Frode Rise, Achim Bechtel, Danica Mitrović, Nataša Đoković, Dragana Životić, Ksenija A. Stojanović.

Upper Miocene depositional environments of the Kikinda-Mokrin High (Serbia)
Saša Ivanišević, Dejan Radivojević (2018)Exploration for oil and gas in mature areas, such as the Pannonian Basin, can benefit from reexamination of old data using more advanced modern workflows that focus on the temporal and spatial aspects of sediment deposition. Specifically, we apply a new environment of deposition model that interprets the Upper Miocene- Pliocene sediments as being deposited in a rapidly filling basin characterized by quick shelf edge progradation from the northwest toward the southeast. Reconstruction of this shelf edge trajectory reveals ...Saša Ivanišević, Dejan Radivojević.
