摘要： A method for determining spatial distribution of proppant incudes using signals detected by seismic sensors disposed proximate a formation treated by pumping fracturing fluid containing the proppant. Origin time and spatial position of seismic events induced by pumping the fracturing fluid are determined. Volume and orientation of at least one fracture in the subsurface formation associated with each induced seismic event are determined. Spatial distribution of a volume of the pumped fracturing fluid is determined using the volume and orientation of each fracture. A length of ellipsoidal axes is selected using a surface defined by a selected fractional amount of the total volume of frac fluid pumped into the formation. Spatial distribution of the proppant is determined using proppant mass, specific gravity and expected proppant porosity in the fractures, and spatially distributing a volume of the fractures within an ellipsoid defined by the ellipsoidal axes.

摘要： A method for correcting a fracture model of a reservoir includes receiving a seismic signal from seismic events due to a plurality of stimulated reservoir stages to provide detected seismic event information and estimating a number of undetected seismic events and a magnitude for each of the undetected seismic events to provide undetected seismic event information for each stage. The detected seismic event information and the undetected seismic event information provide corrected seismic event information for each stage. The method further includes calculating a scaling factor for each stage using a scalar property of the corresponding stage and a reference stage scalar property, applying the scaling factor for each stage to the corrected seismic event information to provide scaled seismic event information for each stage, and correcting the fracture model with the scaled seismic event information for each stage to provide a corrected fracture model.

摘要： Spatial sampling is a key factor in determining acquisition parameters for seismic surveys. Acquiring the data to meet spatial sampling requirements for low, mid and high frequencies, by acquiring coarse, medium and fine acquisition grids respectively and layering these during processing, can result in reduced cost and/or higher quality surveys.

摘要： Passive seismic data is collected from measurements of seismic sensors in respective sensor assemblies, where the passive seismic data is based on measurements collected during periods when no active seismic source was activated. Attenuation of surface noise in the passive seismic data is performed using data from divergence sensors in at least some of the sensor assemblies. The passive seismic data with surface noise attenuated is output to allow for performing an operation related to a subterranean structure using the passive seismic data with the surface noise attenuated.
