Zusammenfassung:Methods, systems, and articles of manufacture consistent with the present invention provide for determining the orientation of natural fractures in th e Earth resulting from hydraulic fracturing treatment. Data attribute information from a far-field point-source signal profile for a microseismic event is extracted in the time domain. An estimate of the orientation of the natural fracture is calculated in the time domain based on the extracted dat a attribute information.
