Imaging Conditions for Primary Reflections and for Multiple Reflections

IM-07 Summary IMAGING CONDITIONS FOR PRIMARY REFLECTIONS AND FOR MULTIPLE REFLECTIONS JIANMING SHENG HONGCHUAN SUN YUE WANG and GERARD T. SCHUSTER WBB Rm 717 Dept. of Geology & Geophysics University of Utah Salt Lake City UT84112 USA Interest in multiple attenuation has been amplified due to the industry trend toward more challenging plays such as deepwater subsalt and sub-basalt areas. Unlike most of the proposed de-multiple methods which separate primary and multiple events prior to migration imaging we present two new approaches which process multiple reflections during migration imaging. In the first approach data are crosscorrelated and the multiples are
