Seafloor-Consistent Multiple Supression
, by Stewart A. Levin
Seabottom multiples and peglegs are predicted in a process
that combines wave propagation and seafloor-consistent
reverberation reflection filters.
Key features of the method are: truly seafloor-consistent filters;
incorporation of the pure seabottom multiple; fitting error minimized
at the surface; and simultaneous design using all the recorded data.
I use this process to suppress strong seafloor peglegs from dipping beds on
a line from the Barents sea for which conventional multiple attenuation
was ineffective.
