  • 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 ...

  • Seismic refraction mapping of fracture swarms in the Western Coalfield of New South Wales, Australia

    The Western Coalfield of New SouthWales, Australiais situated approximately 150 km northwest of Sydney along the western margin of the Sydney Basin. Mining is carried out under the Blue Mountains Plateau, which reaches a maximum elevation of 1100m and is heavily dissected. The main producing seams are the Katoomba and Lithgow seams. They have been ...

  • 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 ...

  • Aquatic Geochemistry

    Aquatic Geochemistry provides a medium for the publication of original studies broadly relating to the geochemistry of natural waters and their interactions with rocks and minerals under relatively near Earth-surface conditions. Theoretical, experimental, and modelling papers dealing with this subject area, as well as papers presenting ...

  • 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 ...

  • Explicit expressions and numerical calculations for the Fréchet and second derivatives in 2.5D Helmholtz equation inversion

    In order to perform resistivity imaging, seismic waveform tomography or sensitivity analysis of geophysical data, the Fréchet derivatives, and even the second derivatives of the data with respect to the model parameters, may be required. We develop a practical method to compute the relevant derivatives for 2.5D resistivity and 2.5D ...

  • Asian Journal of Water, Environment and Pollution

    Asia, as a whole region, faces severe stress on water availability, primarily due to high population density. Many regions of the continent face severe problems of water pollution on local as well as regional scale and these have to be tackled with a pan-Asian approach. However, the available literature on the subject is generally based on ...

  • 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 ...
