Amplitude Versus Offset Classification (AVOC) Using Relative Acoustic Impedance (RAI) Data

N-11 AMPLITUDE VERSUS OFFSET CLASSIFICATION (AVOC) USING RELATIVE ACOUSTIC IMPEDANCE (RAI) DATA ANTHONY N. FOGG Hampson-Russell Software Services Ltd Grove House 551 London Road Isleworth Middlesex TW7 4DS UK Introduction Pre-stack seismic data can be difficult to handle due to the large volumes of data involved and the extensive processing and analysis time required. Using only near and far stacks and no velocity or well data this paper demonstrates the theory behind the new AVOC technology (Amplitude Versus Offset Classification) that yields high-resolution seismic volumes which can be interpreted as a post-stack seismic volume. Resolution of the volume exceeds that
