Claim 0:
1. A method comprising:
receiving, by a computing device 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, by the computing device, 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, by the computing device, a second geocellular grid representing a complex fracture network map of the subterranean formation, 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, by the computing device 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, by the computing device, 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, by the computing device, directions of continuity in the microseismic data by applying the variogram to the microseismic data;
correlating, by the computing device, 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, by the computing device, 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, by the computing device, the subsequent fracturing treatment of the subterranean formation along the second portion of the wellbore using the determined parameters.
