Surface Related Multiple Elimination (SRME)
Surface Related Multiple Elimination (SRME)
SRME is a powerful demultiple tool aimed at removing
all the multiple energy derived from the air/water interface,
including those energies that techniques such as radon and Tau-P
fail to address. Because it requires no velocity information,
we are able to use SRME with onboard processing, and prior to
radon demultiple, to help improve preliminary velocity analysis.
Its ability to handle all of the energy generated from the free
surface allows us to remove even the most complex diffraction
multiples with SRME, and an iterative scheme permits its use in
shallow and deep water settings.

Surface Related Multiple Elimination (SRME)
3D SRME is an extension of the 2D algorithm whereby the full 3D
multiple pattern is modeled to allow the complex multiple shapes,
prevalent around salt bodies and rugose water bottoms, to be more
accurately identified and subsequently subtracted.
Geotrace uses serveral different interpolation routines to help generate the dense input grid. Deregularization allows subtraction on raw shot gathers and helps us maintain AVO integrity throughout the process.
