Evaluation of petroleum geology potential of eastern part of Sava depression by basin modelling : master’s thesis

Istočni dio Savske depresije predstavlja slabo istraženi prostor s obzirom na broj izrađenih bušotina i snimljenih geofizičkih profila. S obzirom da već u ranoj fazi istraživanja nisu nađene ekonomske količine ugljikovodika, područje je proglašeno kao neperspektivno. Za potrebu reevaluacije područja, načinjena je bazenska analiza koristeći programe Petrel E&P Software Platform 2017 i PetroMod 2017. Prilikom obrade trebalo se služiti i geomatematičkim alatima za procjenu litološkog sastava stijena u međubušotinskom prostoru. Kao rezultat dobio se skroman ugljikovodični potencijal na ovome području, premda zbog manjka podataka nije nužno reprezentativan. Načinjeni model može poslužiti kao osnovica za daljnja istraživanja i razumijevanje potencijala prisutnih ležišta ugljikovodika.Despite of interresting local oil outcrops, the Eastern part of the Sava Depression is not sufficiently explored taking in area consideration relatively poor well and seismic data. Because of week economic assessments in the frame of the hydrocarbon potential, the area was in the early phase of field exploration characterized as unprofitable. For the needs of re-evaluation of the area, basin analysis has been using Petrel E&P Software Platform and PetroMod, computer basin modelling programs. The data analysis required geomathematical tools, such as variograms in order to predict distribution of lithological units between the wells. As a final result, programs yielded mediocrity volumes of hydrocarbons in the area of interest. Since the input parameters were scarce, the results of model should not be considered fully representative. They can rather be used as a basis for future explorations
