Wedge Modeling

Understand vertical (thin bed) resolution limits of seismic

Wedge modeling is used to investigate and analyze the effects of spatially varying rock parameters and thickness on the seismic signature. The seismic survey geometry is defined and populated by interpolated mapping of measured or modeled well logs—Vs, Vp, and density. Changes in bed thickness are introduced into the model along with changes in acoustic properties determined through rock physics modeling. A synthetic seismic model is generated from the wedge model by applying a range of wavelet and noise attributes. An interactive environment enables direct comparison between modeled and measured response and direct interaction and update of rock physics, bandwidth, and noise attributes.
