P155 3D ACQUISITION-PRESERVING FOURIER DMO IN THE LOG-STRETCH DOMAIN ANDREY V. MASJUKOV Joint Stock Open Society «Oil-Gas Company «Slavneft» Geophysical R&D Office PO Box 24074 170024 Tver Russia 1 Summary. A 3D F-K DMO method is proposed for the transformation of an elementary crossgather (i. e. 1-fold cube) which shotpoints and receivers are located at two crossing straight lines. If shots and receivers of a cross are regularly sampled along their lines and each receiver records any shot then the method does not encounter offset and azimuth distributions. The main idea is very simple: a true 3D DMO must employ
