Nettet26. mar. 2012 · Compared to linearized inversion, this method is computationally intensive; therefore, Buland and Omre ( 2003) developed a new linearized AVO inversion technique to estimate posterior distributions for P-wave and S-wave velocity, and density. NettetConvoluting this linearized AVO approximation with seismic wavelets, the forward modeling is constructed to combine the prestack seismic records with the fluid … Nettet31. des. 1999 · Abstract: Numerous approaches have been published which derive fluid indicators (often called direct hydrocarbon indicators, or DHI) from AVO equations. The main idea behind these methods is to use the linearized Zoeppritz equations to extract petrophysical parameters such as P-impedance, S-impedance, bulk modulus, shear … golf courses near hamlet nc
