Spectrally Dependent Fault Detection Attribute and Derivative Products: An Application Review in Unconventional Plays

Umberto Barbato, Gabriel Gil, Eshetu Gebretsadik, Gene Sparkman

Abstract

A methodology to produce a phase dependent spectral attribute shows an improvement in accurately mapping seismic discontinuities over conventional geometrical attributes. The presented workflow minimizes windowing effects (both temporally and laterally) observed in industry standard attributes, generally caused by energy leakage, generating uncertainty in the actual position of the discontinuity. This allows the interpreter to have an image that more clearly reflects the structural features captured by the seismic data. Furthermore, other attributes derived from the proposed methodology produce powerful tools to quickly interpret discontinuities, both temporally and laterally. Examples are shown with a focus on unconventional plays, in which fault detection and fracture system characterization present a key element to better understand the reservoir.”
