Sažetak
The Sava Depression, located on the S margin of the Pannonian Basin, contains a number of small oil and gas fields. The depression is filled principially with Neogene sediments resting on Paleozoik cristalline basement. Rifting ocured in Early to Middle Miocene times. Geochemical data imply that Middle to Upper Miocene pelites are good oil-prone source rocks. Most of the oil and oil-gas fields are situated at depths of 370 to 2300 m. Weathered basement rocks and Miocene conglomerates and sandstones are reservoir rocks and the fields are mostly structural and/or structural-stratigraphic traps. Oil from the fields correlate well with the identified source rock facies and maturity level and we propose short migration distances. Sava oil properties show variations in bulk and specific parameters that can be attributed to post-generative processes.
