Compensating finite-difference errors in 3-D migration and modeling
[report]
1990
unpublished
One-pass three-dimensional (3-D) depth migration potentially offers more accurate imaging results than does conventional two-pass 3-D migration for variable velocity media. Conventional one-pass 3-D migration, using the method of finite-difference inline and crossline splitting, however, creates large errors in the image of complex structures. These errors are due to paraxial wave-equation approximation of the one-way wave equation, inline-crossline splitting, and finitedifference grid
