− | Below is a recipe for making a classic integrated structure map from seismic data and well control. It is based on mapping one horizon at a time and must be repeated for each horizon of interest. It may not work in areas with severe static problems (i.e., lots of topography or a rapidly changing weathered layer such as glacial till). It also fails when there are extreme lateral velocity variations in the subsurface (subsalt, subthrust, etc.). When it works, this method gives a map which, by definition, matches every well exactly. It uses seismic time structure to interpolate between wells and extrapolate beyond them. | + | Below is a recipe for making a classic integrated structure map from seismic data and well control.
