RROCESS FOR SEISMIC IMAGING, MEASUREMENT, AND EVALUATION OF THREE-DIMENSIONAL SUBTERRANEAN COMMON-IMPEDANCE OBJECTS

摘要

A diagnostic seismic process (figure 1) for generating, recognizing, and remotely examining subterranean three-dimensional objects (406, 414, 416, 418) or sub-volumes (402) uses processed seismic reflection data (106) to produce high-resolution quantitatively measurable, three-dimensional images of buried objects (406, 414, 416, 418). Examples of such objects are hydrocarbon reservoirs and their encasing rocks, fresh water aquifers, hazardous waste contaminant zones, potential drilling and mining hazards, unexploded military ordnance, caves, tunnels, historical and archeological artifacts and the like. The invention examines the interior portions of underground sub-volumes called common-impedance objects imbedded in a relatively transparent background of seimic impedance sample voxels (402).
