Linearized 2.5-dimensional parameter imaging inversion in anisotropic elastic media

S U M M A R Y In this paper we derive 2.5-D short-period seismic modelling and imaging-inversion formulae in the Born approximation for anisotropic elastic media. The 2.5-D approach encompasses 3-D wave scattering measured in a common-azimuth acquisition geometry subject to 2-D computations under appropriate assumptions. The lowest possible symmetry of the medium in this approach, in principle,...

Linearized and nonlinear parameter variance estimation for two-dimensional electromagnetic induction inversion

Linearized and nonlinear techniques are presented for determining estimates of parameter uncertainty within a two-dimensional iterative Born scheme. The scheme employs low frequency (<100 kHz) magnetic dipole sources in one well, and uses measurements of the vertical magnetic field in a second well to invert for the electrical conductivity distribution between the two boreholes. For computation...

Anisotropic elastic theory of preloaded granular media

A macroscopic elastic description of stresses in static, preloaded granular media is derived systematically from the microscopic elasticity of individual inter-grain contacts. The assumed preloaded state and friction at contacts ensure that the network of inter-grain contacts is not altered by small perturbations. The texture of this network, set by the preparation of the system, is encoded in ...

Linearized Extended Waveform Inversion

The extended model concept links migration velocity analysis and waveform inversion. This abstract presents a method to solve a partially linearized version of the full waveform inversion problem with model extension. Linearization separates the model of the earth into the smooth long scale background model and the short scale model. Extended waveform inversion allows the short scale model to d...

Some remarks on nonlinear AVA inversion in anisotropic media

A feasibility study for inverting reflection coefficients for a single-interface model consisting of a shale overlying a fractured sand is presented. To characterize the medium contact from Amplitude Versus scattering Angles (AVA) behavior associated with the reflection from a particular interface, in view of the anisotropy, wide-angle scattering data are required. However, wide-angle scatterin...
