Unfaulting and unfolding 3d seismic images

WebSEG - Center for Wave Phenomena - Colorado School of Mines WebApr 11, 2024 · Seismic cross-hole tomography produces a 3D interpretation of the subsurface. It involves the measurement of travel times of seismic ray paths between two or more boreholes in order to derive an image of seismic velocity in the intervening ground. The level of detail depends upon the distance between holes, the power of the source, and the ...

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.

WebConglomerate is a type of sedimentary rock that is made up of rounded fragments of various sizes, such as pebbles, cobbles, and boulders. The fragments are typically held together by a matrix of sand, silt, or clay. Conglomerate can form in a variety of environments, such as riverbeds, beaches, and alluvial fans. 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.
