Seismic Attenuation from Vertical Seismic Profiling and Log Data Analysis: A Multi-Well Study

R. Pevzner¹, A. Alasbali¹, R. Galvin¹, B. Gurevich¹, and T. Mueller²

Abstract

All methods for quantitative interpretation of seismic data are based on the analysis of amplitudes of seismic (reflected) waves. Seismic attenuation along the ray path of a wave significantly affects this amplitude information. As such, understanding of this phenomenon has a huge impact for the industry. On top of that, seismic attenuation is a useful attribute by itself applicable for overpressure predictions (Domnesteanu et al. 2002) in oil & gas exploration or as a proxy for shear/heavily faulted zones in mineral exploration.
