Abstract
F015 Unconstrained Multi-parameter AVO Inversion Summary 1 PENGYUAN SUN YANPENG LI XIULI LU EAGE 67 th Conference & Exhibition — Madrid Spain 13 - 16 June 2005 BGP of CNPC Zhuozhou China The use of seismic data for estimation of lithology and reservoir properties is important in seismic exploration and reservoir characterization. In this paper a new method for extraction of the fundamental rock properties from pre-stack PP wave AVO is proposed. Unlike conventional AVO inversions the method re-expresses the PP wave AVO formula (Aki and Richards 1980) in terms of the three different angular reflection coefficients P-impedance reflectivity P-velocity
