Summary:
We present case studies from microseismic monitoring including the Groningen gas field and the Decatur CCS site. We highlight often overlooked monitoring considerations including choice of location algorithm and waveform complexity, and demonstrate how modelling can avoid or mitigate the negative effects. Interpretation of microseismicity can lead to valuable insight into reservoir processes. However, to extract the most value, analyses must go beyond standard processing techniques. We show how combining waveform cross-correlation, full-waveform modelling, travel-time and ray-path analysis, and relative relocation methods can provide the necessary constraints to deliver improved interpretations from microseismic data sets.
