Abstract
A method for internal multiple attenuation of seismic data associated with a subsurface. The method includes receiving seismic data d associated with the subsurface, wherein the seismic data d includes primaries and internal multiples, receiving a first reflectivity rassociated with a first formation in the subsurface, calculating a second reflectivity rassociated with a second formation in the subsurface, based on wavefield extrapolation of the seismic data d and a reflection in the first reflectivity r, wherein the second formation is different from the first formation, calculating the internal multiples using (1) wavefield extrapolation of the seismic data d, (2) the reflection in the first reflectivity r, and (3) a reflection in the second reflectivity r, attenuating the internal multiplies from the seismic data d by subtraction, and generating an image of the subsurface indicative of geophysical features associated with oil or gas resources.
