Rock properties and structural attributes can be combined with an ellipsoid stimulation model around a well bore. A stepwise regression or other optimization analysis can then used to determine what property(ies) and/or attribute(s) has the greatest impact on the shape and properties of a microseismic density volume and can be best used to predict the same. These same properties and/or attributes can then be used to create a microseismic density volume around another nearby well where microseismic data was not recorded to estimated a stimulated reservoir volume.
