Obolon Astrobleme - An Application of 3D Geomodelling and Inversion to Hydrocarbon Exploration

Among other unconventional reservoirs Obolon astrobleme is regarded to be a promising exploration target in Ukraine. Complex and poorly known structure of astroblemes require integration of additional geophysical and geochemical data to commonly used set of seismic and well data. An effective method of joint geophysical inversion was used to build 3D model of Obolon astrobleme which gave possibility to map reservoirs with high probability of hydrocarbon saturation within crater, rim and breccia complex. Research workflow and main results are highlighted in the paper.
