A joint project by the Department of Geology of the Estonian Land Board and the Department of Geoinformation of the Institute of Applied Geosciences at Technische Universität Darmstadt resulted in several 3D-models of northeastern Estonia for (i) better understanding of the sedimentary bedrock, and (ii) evaluating the geopotentials therein. We implemented GOCAD and SKUA software for the first time in Estonia, and as a result, the spatial distribution of the major pre-Quaternary horizons (Devonian, Ordovician, Cambrian, Neoproterozoic and Crystalline Basement) was clarified. Two larger scale models of oil shale prospects enable the calculation of the thickness and volume of the mineral reserves. Due to the quality control of the input data during the modelling process different stakeholders like governmental authorities, research institutions and mining industry can achieve great benefits by pooling their resources, such as the identification of 135 wells with incorrect coordinates or drilling location.
