Jones (University of Bristol) SUMMARY We outline an imaging procedure for micro-seismic events recorded on seismic arrays. The approach is based around stacking all the data consistent with an arrival from a particular time and point in the reservoir. The method does not require any hands on analysis of the data such as picking arrival times which makes it ideal for the application to large arrays of surface sensors. We present results of the migration applied
