3-D seismic discontinuity for faults and stratigraphic features: The coherence cube
Conference

OSTI ID:542822
Seismic data are traditionally acquired and processed for the purpose of imaging seismic reflections. This paper describes a method of processing seismic data for the purpose of imaging seismic discontinuities (U.S. and foreign patents pending, Bahorich and Farmer). Discontinuities include faults and stratigraphic features. One application of this non-interpretive process results in a 3-D data volume, or {open_quotes}cube{close_quotes}, of coherence coefficients, within which faults are revealed as numerically separated surfaces. Figures 1a and 1b compare a traditional 3-D reflection amplitude time-slice with the results obtained by applying the new method to it. This is the first known method of revealing fault surfaces within a 3-D volume for which no fault reflections have been recorded.
