Statistically Uncorrelated AVO Attributes

P187 STATISTICALLY UNCORRELATED AVO ATTRIBUTES PHILIPPE HERRMANN and GUILLAUME CAMBOIS Abstract 1 AVO analysis rely on characteristic AVO attributes derived from the amplitude behavior of the back scattered seismic wave field recorded over a range of offsets (or angles AVA). An early settled practice consists in the production of two stacks: a near offset stack (with the first half range of offsets) and a far offset stack (with the second half range of offsets). The two above mentioned AVO attributes fulfill two important requirements: (1) High signal to noise ratio: compared to the individually recorded traces the S/N ratio is
