WebBorn elastic modeling. Each point within the reservoir volume is considered as an independent point diffractor of much smaller size than the wavelength of the incident … WebFor elastic Born modeling, these equations must be linearized. Beylkin and Burridge (1990) show a full derivation of linearized scattering for an elastic solid. Using r = 1 ρ to …

The legacy model (Figure 3a) was built using a top-down salt model building process with tremendous efforts made in salt scenario testing. Most of the salt scenario work was conducted within the dashed circle area. The OBN RTM image from the legacy model had strong migration swing contamination and dimmer amplitudes compared to mottled liver appearance ultrasound

WebFor elastic Born modeling, these equations must be linearized. Beylkin and Burridge (1990) show a full derivation of linearized scattering for an elastic solid. Using r = 1 ρ to denote the specific volume, we have three models for the elastic isotropic case: r = r0 +∆r, λ = λ 0+∆λ, µ = µ +∆µ, (4) WebOct 19, 2024 · To solve this problem, we have extended the pseudoinverse Born operator from acoustic to elastic media to account for the elastic amplitudes of PP reflections and provide an estimate of physical density P- and S-wave impedance models. We restrict the extension to marine environments, with the recording of pressure waves at the receiver … WebJun 1, 2009 · Forward modelling of any data event in a reflection seismic experiment with the Born series requires the calculation of a large number of terms, if the perturbation is large and spatially extended. Various partial series summations, the De Wolf approximation for instance, can be devised to separately model primary reflections. healthy pregnancy snacks for work
