Method for determining aggregate fracture properties for evaluation of fracture procedures

1. A method for imaging microseismic events, comprising:

in a computer, determining a hypocenter of microseismic events generated by at least one stage of a hydraulic fracturing procedure from recorded signals detected by seismic sensors disposed above a wellbore in the subsurface;

in the computer, determining spatial position of the microseismic events occurring sequentially in the fracturing procedure with reference to a center of fracturing procedure;

in the computer, assigning each microseismic event to one of a plurality of equal, selected size bins defined positionally with reference to the center of the fracturing procedure;

in the computer aggregating seismic moment of each microseismic event assigned to each bin; and

in the computer generating an image of the aggregated seismic moment with respect to position referenced to the center of the fracturing procedure.

2. The method of claim 1 further comprising determining at least one of a well spacing and a fracture stage spacing using the image.

3. The method of claim 1 wherein the image is displayed in a vertical plane transverse to a trajectory of the wellbore.

4. The method of claim 1 wherein the image is displayed in a horizontal plane.
