Black hole boundary conditions

机译:黑洞边界条件

摘要

The present disclosure provides a method for modeling and analyzing the impact of different seismic surveying and imaging techniques on a subterranean formation by creating a black hole boundary condition around a particular region in the formation where at least one of the physical characteristics is unclear and may distort the seismic modeling results. The black hole boundary conditions will eliminate any energy wave that enters, exit or reflect off the region so as to avoid any image distortion caused by this region. The resulted image data is compared with the image data obtained without using the black hole boundary conditions to determine the impact of this region, and proper correction can be made to more precisely and accurately model the formation
