Design of a combined cube of seismic data acquired in areas of complicated relief by use of various seismic source types

Abstract

The paper gives brief information on the study area with attention focused mainly on complex surface seismic and geological environment, stipulating the use of 3D seismic survey in this area. As the area features complicated relief, the sources and receivers have been chosen individually for each location of the survey. Seismic energy sources generated various seismic oscillations and this complicated the design of combined 3D cube for the whole study area. By use of modeling we have reduced all oscillations to the minimal-phased form. The next stage of processing consisted in use of shifts of time sections for combination of seismic boundaries acquired for various parts of the area: onshore, offshore, swampy areas. Thus, applying the standard procedures it was possible to design combined 3D cube.
