F-5817-L ABSTRACT A process for monitoring real-time hydraulic fracture propagation wherein remote microseismic activity is utilized. Selectively placed geophones detect generated longitudinal and shear-waves which give an estimate of direction of the fracturing. Having obtained the direction of the fracture, polarization is used to obtain the fracture source. Subsequently obtained microcracks which define the main fracture boundary are recorded as microseismic events. Microcracking in the formation is sequenced in time thereby allowing the real-time fracture height to be estimated.
