Abstract
Most migration methods produce either common-offset-gathers (COG) or common-angle-gathers<br>(CAG) gathers. But none produce both, that is until now. We have developed an accurate and efficient<br>method that converts common offset image gathers to common angle image gathers, or vice versa.<br>The practical uses of the method are for velocity analysis or AVO studies using existing commercial<br>toolkits.
