Algorithm helps define final 3D seismic survey polygon
01/12/2009
The design of a 3D seismic survey depends on a number of field parameters that control the patch geometry and layout of source and receiver lines.A 3D seismic survey is planned over a subsurface geologic target area, usually picked from interpreted 2D migrated seismic data. Due to the presence of dips, this migrated subsurface area is expanded into unmigrated surface area, which in turn is further expanded into the final survey area, in order to get full fold coverage over the target area.In most cases, except star and radial layouts, the initial design starts with source and receiver lines in the form of a rectangular grid, which is interactively clipped at the edges according to the sha...
