A velocity model building technique for pre-stack depth migration

Autor: C. Barton, M. A. Brzostowski, G. F. Mills, S. Ridgway

Publikováno v: 54th EAEG Meeting.

As exploration in complex geology areas becomes more prevalent, the ability to estimate the migration velocity field in such regions will be one of the key elements in the processing sequence. Due to the presence of lateral velocity variations (actua

3-D tomographic model study

Autor: G. A. McMechan, M. A. Brzostowski

Publikováno v: 54th EAEG Meeting.

We evaluated the applicability, of the Simultaneous Iterative Reconstruction Technique (SIRT) in a 3-D environment. Synthetic travel times were generated for various 3-D geometry configurations. We then inverted the synthetic travel times for velocit

High-dip time migration

Autor: M. A. Brzostowski, J. L. Black, H. Crook

Publikováno v: 53rd EAEG Meeting.

We introduce a steep-dip time migration algorithm which exploits the strenghts of current time migration algorithms and minimizes their weaknesses. This new time migration scheme uses Stolt and phase-shift migration as a base and finite-difference mi

Steep-dip time migration and residual depth migration

Autor: M. A. Brzostowski, J. L. Black

Publikováno v: EAGE/SEG Research Workshop 1990.

Common practice is to perform steep-dip time migration followed by an image-ray correction. This paper examines the image-ray correction and finds it lacking. In particular, this correction is valid only for the small-dip portion of the migrated imag
