3D primary estimation by sparse inversion using the focal domain parameterization

Recently, a new approach to multiple removal has been intro- duced: estimation of primaries by sparse inversion (EPSI). Al- though based on the same relationship between primaries and multiples as surface-related multiple elimination (SRME), it involves quite a different process: instead of prediction and subtraction of multiples, in EPSI the...

Closed-Loop Surface Related Multiple Estimation

Surface-related multiple elimination (SRME) is one of the most commonly used methods for suppressing surface multiples. However, in order to obtain an accurate surface multiple estimation, dense source and receiver sampling is required. The traditional approach to this problem is performing data interpolation prior to multiple estimation. Though...
