Identifying wellbore location based on seismic data

A seismic analysis method comprising:

• receiving seismic response data for a seismic response associated with a seismic excitation in a subterranean region, the seismic excitation generated by a plurality of seismic sources each in a first directional wellbore section in the subterranean region, the seismic response detected in a second directional wellbore section in the subterranean region, wherein the plurality of seismic sources are placed in the first directional wellbore section after drill strings have been removed from the first and second directional wellbore sections and the first and second directional wellbore sections have been cased and cemented;
• identifying, by operation of a computer system, a location of a fracture treatment injection wellbore that has been completed in the subterranean region based on the seismic response data;
• and
• dynamically mapping created fractures, by operation of the computer system, with the seismic response data to determine which perforation clusters in the completed fracture treatment injection wellbore have fracture systems initiating from them and an extent of fracture propagation from each perforation cluster.
