International ClassG06F 019/00AbstractA processing system stores a special software known as the Cubemath software. The Cubemath software allows the processing system to process, analyze, and interpret a second set of seismic data relative to a first set of seismic data obtained from either a repeat seismic operation or a single seismic two processing method operation. A first set of 3D seismic data is collected at a particular location on the surface of the earth at time "t1", and a second set of 3D seismic data is collected at that same particular location on the surface of the earth (at a different time "t2" when the repeat seismic operation is being performed). The processing of the second set of seismic data relative to the first set of seismic data is accomplished by: selecting either a volume or a surface to represent the first set of seismic data, selecting either a volume or a surface or a trace or null to represent the second set of seismic data, selecting a specific mathematical operation, selecting a specific type of output (such as a volume output or a surface output), executing a run thereby performing the mathematical operation on the first set of seismic data and the second set of seismic data, and generating a set of data results on an output record medium presented to an operator in the form of the selected type of output.Other References
