Stochastic Beta Deconvolution (SBD)

Borehole-constrained spectral shaping for enhanced vertical resolution

Conventional spectral shaping techniques often rely on several limiting assumptions as to the nature of the earth. These might include "white" earth reflectivity, a stationary seismic wavelet, minimum phase, and the absence of noise.

WesternGeco uses borehole data to replace these assumptions with information that more accurately models Earth properties - maximizing the vertical resolution available in the data based on sound geophysical principles.

Stochastic beta deconvolution (SBD) is applied pre- or poststack and can produce superior results compared to more generic spectral shaping techniques. Combined with well-tie analysis, stochastic beta deconvolution forms an integral component of any Well-Driven Seismic workflow.
