Noise, the What, the Where and the How To

The ability to deliver drastic improvements in signal to noise ratio are a key step to enhancing the results of passive seismic surveys - whether short or long term; carbonate or clastic formation; deep or shallow; and fluid or steam stimulated. Across the board noise is the primary enemy of passive seismic. The authors detail advances in noise filtering and reduction techniques and detail the journey to automation of this technique as an embedded DSP routines directly onto the data acquisition system. Selected case studies will be detailed and explained in terms of data fidelity and the practical relevancy of associated benefits.
