摘要： A method of mapping subsurface fracture geometry below a surface of the ground includes two independently powered systems, namely a plurality of sensors distributed through a hole in the subsurface and a downhole tool to facilitate reception and transmission of signal data from the plurality of sensors. The sensors are distributed into fissures within formations that have been hydraulically fractured. The sensors send signal data to the downhole tool for transmission to a unit on the surface. The signal data permits for the mapping of the fissures within the fractured formations.

摘要： In one embodiment, the invention utilizes computer models to calculate predicted spectral estimates that may be encountered during a hydraulic fracturing operation. Seismic events generated by hydraulic fracturing are mapped and displayed upon a graphic user interface. Spectral attributes of selected seismic wave field data from the fracture operation are derived and compared to predicted spectral estimates that match one or more characteristics of the formation. The comparison may be utilized to generate a predicted hydrocarbon content for the fracture zone of the formation and to adjust or alter the hydraulic fracturing operation in order to maximize hydrocarbon recovery.
