Abstract
The authors describe the successful practices of using the results of interpretation of modern azimuthal logging in horizontal wells in the geological modeling that allowed to update the boundaries of clinoform geological bodies and to assess the reliability of the separated boundaries (in combination with the seismic data). The authors have developed an approach to evaluating the porosity of net sandstone taking into account the proportion of its coverage by a horizontal well according to RHOB data that allowed to properly describe the structure of the near-wellbore space in a geological model of inhomogeneous reservoirs, while the use of restrictive NTG ranges for each lithotypes allowed to keep initial reservoir connectivity when transferring the results of logging data interpretation into the geological model grid that resulted in the updated oil-bearing areas of individual clinoforms.
