Abstract

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 to the Life of Field Seismic (LoFS) array. Despite their preliminary nature the results permit some initial conclusions. In particular they demonstrate the ability of The LoFS array and our processing scheme for imaging micro-seismic events. They also highlight the importance of ray coverage and using arrival angle information when imaging events at or beyond the edge of the array.
