Abstract: A method may include obtaining well log data for various wells regarding a geological region of interest. The well log data may correspond to various well logs with different logging types. The method may include assigning, using a grouping algorithm, subsets of the well log data to various groups based on one or more geological attributes. The method may include determining, using the groups and a machine-learning algorithm, various well zones for different portions of a respective well among the wells. The method may include determining interpolated log data using the well log data, the well zones, and an intrawell interpolation process. The method may include generating a formation property volume based on the interpolated log data and the well log data.
