Abstract
Summary
In the algorithms of geostatistical inversion, when each new trace is formed, not the well corresponding to geological facies, but the nearest well has the highest weight.At the heart of this work is the assumption that the wellscorresponding to different geological facies and havingmostly different lithological composition should not have influence on distribution of the properties of each other in the model. Refinement of the spatial distribution of the properties in the implementation of seismic geostatistical inversion can be a solution to this problem. Proposed approach allows to refine the spatial distribution through the use of information on the arrangement of geologic facies obtained from seismic data.
