The removing of multiple reflections from a curved interface at the common-source seismogram

Abstract

The proposed simplified version of the original solution for the actual problem of removing multiple reflections from a curved interface at common-source seismogram is suggested. The solution to this problem is complicated in the framework of the approach based on using a reflected wave’s hodograph. The proposed solution is based on the analytical expression for describing a reflecting interface structural form. The expression is obtained using the location algorithm based on solving only direct kinematic seismic problems. There is an analytical expression; one can calculate the propagation paths of the multiple reflections and its arrival times at the receivers of the observation base. If a seismic wavelet is detected in a limited range, including a multiple reflected wave arrival time, it is possible to remove the detected wavelet for eliminating its distorting effect to the direct reflected signal.
