  • 3-D frequency-domain seismic wave modelling in heterogeneous, anisotropic media using a Gaussian quadrature grid approach

    We present an extension of the 3-D spectral element method (SEM), called the Gaussian quadrature grid (GQG) approach, to simulate in the frequency-domain seismic waves in 3-D heterogeneous anisotropic media involving a complex free-surface topography and/or sub-surface geometry. It differs from the conventional SEM in two ways. The first is the ...

  • Extrapolation of vector (elastic) displacements by displacement potential field continuation

    Extrapolating recorded elastic displacement data from the surface downwards is the first step of a two-step elastic migration scheme. The second step is the image formation condition. Although an elastic (vector) reverse time migration can extrapolate elastic displacement data downwards, the subsurface reflections and the loss of energy due to the ...

  • Solutions, algorithms and inter-relations for local minimization search geophysical inversion

    This paper presents in a general form the most popular local minimization search solutions for geophysical inverse problems—the Tikhonov regularization solutions, the smoothest model solutions and the subspace solutions, from which the inter-relationships between these solutions are revealed. For the Tikhonov regularization solution, a variety of ...

  • Crosshole acoustic velocity imaging with full-waveform spectral data: 2.5-D numerical simulations

    This paper focuses on the question of full-waveform inversion and the use of crosshole full-waveform spectral data. We examine the differences in effectiveness of each form of data (real, imaginary, amplitude, phase and Hartley spectra) and determine which is best for imaging the velocity distribution. By 2.5-D numerical simulation for three ...

  • Crosshole resistivity tomography using different electrode configurations

    This paper investigates the relative merits and effectiveness of cross-hole resistivity tomography using different electrode configurations for four popular electrode arrays: pole–pole, pole–bipole, bipole–pole and bipole–bipole. By examination of two synthetic models (a dipping conductive strip and a dislocated fault), it is shown that besides ...

  • A synthetic study on crosshole resistivity imaging using different electrode arrays

  • A new method for crosswell reflector imaging

    Imaging seismic reflectors with crosshole and VSP tomographic data is only occasionally carried out using Kirchhoff-style migration schemes. We introduce a new kinematic method here for tomographically imaging reflectors. The scheme first picks up traveltimes of each reflected event from common-shot gather tomographic data. It then uses the picked ...

  • Composite boundary‐valued solution of the 2.5-D Green’s function for arbitrary acoustic media

    Theoretically, the Green’s function can be used to calculate the wavefield response of a specified source and the Fréchet derivative with respect to the model parameters for crosshole seismic full‐waveform inversion. In this paper, we apply the finite‐element method to numerically compute the 2.5-D Green’s function for an arbitrary acoustic medium ...
