摘要： A method for estimating a volume of a stimulated reservoir includes receiving a seismic signal having a magnitude from each detected microseismic event in a plurality of detected microseismic events in an earth formation to provide detected microseismic event information. The seismic signal is received by an array of seismic receivers. The method further includes estimating a number of undetected microseismic events and a magnitude for each of the undetected microseismic events to provide undetected microseismic event information where the number of undetected microseismic events and corresponding magnitudes are estimated using each of the detected microseismic events and corresponding magnitudes. The method further includes estimating the stimulated reservoir volume using the detected microseismic event information and the undetected microseismic event information.

摘要： A method for estimating a volume of a stimulated reservoir includes receiving a seismic signal from each microseismic event in a plurality of microseismic events in an earth formation by an array of seismic receivers. The method further includes representing each microseismic event by a plurality of markers in the three-dimensional space. A spatial distribution of the markers represents a volume of rock influenced by a microseismic event, wherein the volume and a location of each event are derived from the seismic signal. The method further includes calculating a scalar attribute for each marker in the plurality of markers, dividing the three-dimensional space into a plurality of three-dimensional grid cells, and summing the scalar attributes for all the markers in each grid cell to provide a total scalar attribute for each grid cell.
