    Diffraction tomography is the generalization of X-ray tomography to applications such as seismic exploration where diffraction effects must be taken into account. In this paper, the foundations of diffraction tomography for offset vertical seismic profiling and well-to-well tomography are presented for weakly inhomogeneous formations for which the Born or Rytov approximations can be employed.

    This paper considers the problem of inverting single loop transient electromagnetic data from a spherical conductor. First, analytical expressions are presented for the transient voltage, and then the various partial derivatives of this voltage with respect to the parameters of the ground are found. Secondly, it is shown how all these expressions can be used with existing inversion schemes, such a... View full abstract»

    A procedure is described for interpreting the results of direct current resistivity measurements in regions where the underlying structure cannot be assumed to be layered but varies little in the ¿strike¿ direction. Automatic inversion of the data is performed with the subsurface model having an arbitrary 2-D conductivity distribution. Results of such inversion are shown for both simple models a...

  • Influence of Inhomogeneities in a Stratified Ground on the Field of a Circular Loop Antenna

    Publication Year: 1984, Page(s):29 - 34

    This paper extends earlier works on three-dimensional scattering from a finite obstacle in a stratified halfspace, treated by means of the T-matrix method. In this paper we consider a general source configuration above the ground, that excites the subsurface medium and its inhomogeneity. Explicit expressions are given for the magnetic dipole, the circular, and rectangular antenna loops. Numerical ... View full abstract»

  • General Formulation of the Induction Logging Problem for Concentric Layers about the Borehole

    The electromagnetic theory of induction sounding in boreholes is developed for the general case where the formation adjacent to the hole is concentrically stratified with any number of layers. The final solution of the boundary value problem is expressed in the form of an equivalent nonuniform transmission line. Any one or more of the sections can have a radial variation of the electrical properti... View full abstract»

  • Reflection And Transmission of Electromagnetic Waves at a Rough Interface between Two Different Media

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4430 KB)

    An iterative technique is developed to rigorously compute the electromagnetic wave reflection and transmission at a rough interface between two media. The method is based upon a wave-function expansion technique in which the electromagnetic field equations and the radiation condition are satisfied analytically, while the boundary conditions at the interface are satisfied numerically. The latter is... View full abstract»

  • Computation of Scattering from Penetrable Cylinders with Improved Numerical Efficiency

    An integral-equation formulation is used to obtain numerical results for the scattered fields of a penetrable cylinder immersed in either a lossy halfspace or a lossy homogeneous medium. The cylinder is iluminated by a parallel electric line source. A set of plane waves interior to the inhomogeneity (scatterer) is used as basis functions. This results in more than an order of magnitude decrease in... View full abstract»

  • Block Diagonalization of the Electromagnetic Impedance Matrix of a Symmetric Buried Body Using Group Theory

    Publication Year: 1984, Page(s):62 - 69

    A major problem with the volume-current integral-equation technique of three-dimensional electromagnetic modeling is the computational time and-storage required to form and solve the impedance matrix equation for the scattering currents. If the horizontal cross sections of a body with vertical sides all possess a certain symmetry, the matrix contains information about the effect of the symmetry on... View full abstract»

  • The Detection of Induced Polarization with a Transient Electromagnetic System

    Publication Year: 1984, Page(s):69 - 80

    The study of two-dimensional TEM models consisting of a cylinder in a conductive host using measured rock properties show that TEM surveys are capable of detecting induced polarization (IP) effects. A case history showing a comparable type of response is presented. The IP effects manifest themselves in extreme cases as negatives in the response and in other cases as anomalously high apparent resis... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4231 KB)

    Electrical methods using buried transmitters or receivers have become increasingly important exploration tools as exploration for deep mineral deposits has increased. A variety of resistivity methods have been developed and tested for borehole applications to mineral exploration, from simple mise-a-la-masse hole-to-surface arrays to more complicated hole-to-hole arrays. Time and frequency domain E... View full abstract»
