Paper Summary
Improving the bandwidth of seismic data has been an ongoing endeavour in increasing the usability of seismic data in many plays throughout the world. While various broadband acquisition techniques have been recently developed for marine acquisition, the most significant issue for land seismic has been the low signal-to-noise ratio, particularly at the low and high ends of the frequency spectrum. In this paper, we describe a frequency-dependent filtering technique that can significantly increase the available bandwidth of the seismic data. We show a field data example and demonstrate that the enhanced bandwidth seismic data ties with well logs in the area.
