Application of geostatistics in description of turbiditic depositional environments, case study Kloštar Field, Sava Depression

Geological variables of Pannonian and Pontian reservoirs sandstone series were analyzed in the Kloštar Field, which is located west of Moslavačka gora Mt. Clastic source during Late Pannonian and Early Pontian were Eastern Alps, and material had been several times re-deposited until reached the western part of the Sava Depression. However, palaeogeographic analysis open possibility that Moslavačka gora Mt. had some influence as a minor source of clastics in mentioned periods, giving material transported probably in short alluvial fans. This analysis tends to prove that the local palaeorelief had role as sources of clastics around the Kloštar structure, and consequently in other places in the Sava Depression close to uplifted palaeorelief. Indicator Kriging and Sequential Gaussian Simulations of depth, thickness and porosity were performed for the largest Late Pannonian and Early Pontian reservoirs. The Late Pannonian sandstones are more compact, also characterized by more mica minerals. Recognized are two patterns of turbiditic activities. In one, detritus was transported from northwest, but in the second direction of transport shifted from north. The main turbidite currents came from north/northwest passed between Kalnik and Moslavačka gora Mts. Simulations Gaussian maps showed such north-south trend for Early Pontian and indicator maps prevailing direction of main depositional channel northwest- southeast.
