SUMMARY The SH-wave inverse problem of a 2-D transversely isotropic (TI) elastic medium, with arbitrary orientation of symmetry axes, is approached using a linearized waveform imaging method. the theory is developed for isotropic and TI parameter inv

A crosswell seismic experiment at the San Emidio oil field in Bakersfield, California, is carried out to evaluate crosswell reflection/diffraction tomography and image the interwell region to locate a possible pinchout zone. In this experiment, the t

SUMMARY An inversion method that stabilizes the multiparameter inverse problem for a constant background elastic isotropic medium is developed. The inverse problem is formulated in the wavenumber domain and the operators acting on the individual elas

Two diffraction tomography techniques are applied to crosshole field data to detect fractures in granitic rock. The techniques used are the conventional back‐propagation method and a new quadratic programming method incorporating constraints. In th

Estimation of a velocity model prior to AVO migration / inversion forms an important processing step that has impact on the accuracy of the final result. In fact, due to the non-linearity of the inverse problem, there could be a number of velocity mo
