Abstract

The quasi-random migration (QM) method is tested on 3-D seismic data from West Texas. Results show that the QM images, at l/4 subsampling of the entire data set, has moderately better quality than the regularly migrated (RM) images obtained from a regular l/4 subsampling of the original data. However, it appears that there are fewer artifacts in the QM images than in the regular images. Previous studies suggested that the QM images should be of much higher quality than the regularly sampled images. Our field test results did not show this to be true because the source and receiver lines were spaced more than 1300 feet apart, and so did not allow for a good quasi-random subsampling of the data.
