Abstract
A method for determining the approximately length and the azimuth of a hydraulic fracture after it has been formed in a subterranean formation without requiring the use of dedicated monitor wells or the need for positioning sensors at subsurface locations. Basically, the present method involves the comparison of routine, seismic surveys carried out at the surface before and after the fracture is formed to thereby determine the approximate length and azimuth of the fracture.
