Volumetric and non-volumetric sources-based seismic survey and method

摘要

A seismic survey system (400) for surveying a subsurface. The system includes a volumetric land source (402a) buried underground for generating P-waves; a non-volumetric land source (402b) buried underground for generating P-and S-waves; plural receivers distributed about the volumetric and non-volumetric land sources (402a, 402b) and configured to record seismic signals corresponding to the P- and S-waves; and a controller (430) connected to the volumetric land source (402a) and the non-volumetric land source (402b) and configured to shot them in a given pattern.
