Unfaulting and unfolding 3d seismic images

WebOct 18, 2015 · Fault surfaces are often represented by triangle or quad meshes, which are more complex than the arrays used to represent seismic images, and are more complex than necessary for subsequent processing tasks, such as that of automatically estimating fault slip vectors. To address this limitation, we propose to combine a method for automatic image unfaulting with seismic image flattening. First, using fault surfaces and fault throw vectors estimated from an image, we interpolate throw vectors to produce a throw vector field, which we use to unfault the image.
