3D Geological Modelling of Achimov Formations Ach3-4, Ach52-3 and Ach6 of “N” and “V” License Areas

The goal of this work is to show how to increase a forecast ability of 3D geological (static) models of Achimov formations Ach3-4, Ach52-3 and Ach6. For this purpose all available data was analysed and modern sequence stratigraphic approaches as well as core and 3D seismic information are used. The method for net sand volume computation from 3D seismic data utilizing “Genetic inversion algorithm” is implemented. The created net sand volume is used as 3D trend during further geological modelling for Achimov formations of “N” license area. Seismic attributes and improvements in petrophysics are broadly used for 3D geological modelling of “V” license area together with the new correlation based on detailed core and log analysis.
