Abstract

Monitoring fracing induced seismicity is an important and developing technique of modern reservoir operation practice. The large numbers of small magnitude events, as well as the increasing number of instruments used, make manual detection, selection and picking of events a tedious, costly and time consuming task. In that scope, an algorithm is presented that automatically detects and picks arrival times for P-waves and S-waves, as well as pulse width picks. In particular, automatic processing of a seismic record consists of 3 steps: (i) detection of seismic events in a given record, (ii) estimation of the P-wave arrival time, as well as zero-crossing (pulse width) and finally, (iii) estimation of the S-wave arrival time. The algorithm is applied and validated on a dataset collected during the acid fracturing of a reservoir.
