Modeliranje potpovršinskih odnosa na području široke okolice Velike Gorice

Abstract: The purpose of this theis was to digitalize the structural maps and the paleorelief map of the western part of Sava Depression and make a 3D model that could later be used in regional exploration of hydrocarbon reservoirs. Six maps were constructed in total. One by pre-Neogen border (Tg) and five on E-log markers (Rs7, Rs5, Z ', Rφ and α'). The maps were originally constructed by PhD Josipa Velic, Professor Emeritus for her doctoral thesis made in the 1980'. The digitization of the structural maps and the paleorelief map were made in the computer program ArcMap 10.1 and the three-dimensional model of the subsurface was made in the computer program PetrelTM 2014. Research area is mostly situated around the city of Velika Gorica along with Zagreb and Sisak - Moslavina county, which roughly coveres 960 km2. The surfaces of 78 faults were designed and defined. Calculated statistical deviation of the model was an average of 0.6348%, which confirms high accuracy and precision when comapred to the original data.
