Claim 16:
17. A non-transitory computer-readable medium encoded with instructions that, when executed by a processor, perform a method comprising:
receiving, from a wellbore tool placed along a wellbore extending into a subterranean formation, well log data collected by the wellbore tool for different points of the subterranean formation surrounding the wellbore, the well log data including measurements of one or more properties of the subterranean formation that relate to fractures within the subterranean formation;
generating a first geocellular grid representing a natural fracture network map of the subterranean formation, based on the well log data collected by the wellbore tool prior to a fracturing treatment of the subterranean formation, wherein the first geocellular grid includes a plurality of cells, and each cell of the plurality of cells represents the well log data collected for a corresponding point of the subterranean formation;
generating a second geocellular grid representing a complex fracture network map of the subterranean formations based on the first geocellular grid and additional well log data collected by the wellbore tool for the different points of the subterranean formation during the fracturing treatment along a first portion of the wellbore within the subterranean formation;
receiving from one or more sensors, microseismic data collected by the one or more sensors for the different points of the subterranean formation during the fracturing treatment along the first portion of the wellbore within the subterranean formation; calculating a variogram representing the microseismic data collected by the one or more sensors for the different points of the subterranean formation as a function of spatial location;
identifying directions of continuity in the microseismic data by applying the variogram to the microseismic data;
correlating the directions of continuity identified in the microseismic data to fracture locations in the complex fracture network map to produce a microseismic-weighted (MSW) complex fracture network map of the subterranean formation, the fracture locations corresponding to cells of the second geocellular grid representing one or more fracture planes within the complex fracture network map;
determining parameters for a subsequent fracturing treatment of the subterranean formation along a second portion of the wellbore, based on the MSW complex fracture network map; and
controlling, the subsequent fracturing treatment of the subterranean formation is performed along the second portion of the wellbore using the determined parameters.
