Prestack v(z) f-k migration images for Blackfoot III 2D multi-component data: an update

Xinxiang Li, Gary F. Margrave and Colin C. Potter

ABSTRACT

This paper shows some updated images from Blackfoot III 3C-2D data. The images from the vertical-component data with highly focused target sand-channel tie very well with the synthetic seismograms in relative depth, even though the imaged target-depth does not exactly match the geological depth. As for the images from the radial-component data, the updated images have higher quality, because the results previously shown were erroneously migrated from asymptotic common conversion point (ACCP) binned radial-component data. Some quality control procedures to determine if the data has been ACCP binned are also discussed.
