Impact of an integrated seismic data processing approach
Published 1992“…The fifth is an event specific AVO inversion technique based on the fact that for a given porous lithologic unit, the behavior of the P-wave reflection amplitudes versus offset will vary depending on whether the pore spaces are filled with water, oil or gas. Data examples show that the above mentioned integrated seismic approach increased the interpreter's confidence of the prospect and led to a successful drilling program.…”
