A pilot case study of microseismic monitoring using a single vertical receiver array in an onshore oilfield in Abu Dhabi is presented. For the majority of the data, the background noise level is high (SNR<1 db), which makes it very challenging to find well-defined P and S waves simultaneously. A total of 180 potentially injection/production induced microseismic events have been detected by a combination of band-pass filtering, STA/LTA and apparent velocity estimation methods. However, further analysis such as time-frequency analysis, matched filtering method and hodogram analysis are still required to suppress the noise and verify the events.
