Tehničko tehnološki parametri izrade bušotine X
Marko Savović (2024)U ovom završnom radu obrađena je analiza i procena efikasnosti bušenja u naftnom polju X, uz poseban osvrt na probleme vezane za osipanje lapora i bubrenje gline.Istraživanje je sprovedeno sa ciljem unapređenja bušačkih metoda, optimizacije bušaće opreme i minimizacije zastoja tokom rada. Detaljno su prikazane faze bušenja, cementacija zaštitnih cevi, testiranja. Rad uključuje analizu postignutih kapaciteta ispiranja, performanse korišćenih alata, te preporuke za poboljšanje efikasnosti bušenja. Rezultati pokazuju da su glavni problemi nastali u formacijama sa nehomogenim svojstvima, kao ...... arheolozi.

Detecting the boundaries of gravity anomaly sources using the vertical and tilt derivative
In geophysical exploration, it is important to define the boundaries of anomaly sources that are not visible on the surface. Information about the boundaries of sources can help during geophysical geological modeling of the survey area. A model of the survey area can help in better defining the geological structure and geological development of an exploration area. This paper presents how the procedures of vertical and tilt derivative on gravity data can help to detect the ...Snežana Ignjatović, Ivana Vasiljević, Branislav Sretković.

Tektonska evolucija ugljevičkog basena (Bosna i Hercegovina)
Slobodan Dragić (2024)U radu je prezentovana šira slika tektonske evolucije ugljevičkog basena, kao i Dinarida uopšte. Prikazani su litostratigrafski odnosi istraživanog područja, kao i kratak pregled tektonskih jedinica koje se nalaze u domenu basena. Najveća pažnja posvećena je kinematskoj analizi rasjednih struktura i interpretaciji podataka u svjetlu tektonske evolucije basena. Ugljevički basen zapunjen je oligocensko-miocenskim sedimentima, a njegovu osnovu grade paleozojsko-mezozojske formacije. Najstarije tvorevine na ovom području su permski sedimenti.

Развој хибридног модела за оптиматизацију завршне контуре одлагалишта у површинској експлоатацији лежишта минералних сировина
Aлександар Додеровић (2024)Површинска експлоатација минералних сировина захтијева претходно откопавање значајних( милионских) количина јаловине, које је неопходно транспортовати до локације на којој ће сеона трајно одложити. Традиционални приступ избора локације и дизајна одлагалишта се карактерише парцијалним приступом, заснованом на анализи неколико водећих критеријума као и на личном искуству инжењера, често занемарујући синергетски ефекат осталих утицајних фактора Технолошке операције које се односе на манипулацију јаловином, међу којима предњачи транспорт, генеришу највећи дио трошкова у површинској експлоатацији.
