Us Patents

  • Two-Component Acoustic Borehole Tool

    view source
  • US Patent:
    45787859, Mar 25, 1986
  • Filed:
    Jun 6, 1983
  • Appl. No.:
    6/501614
  • Inventors:
    Valery A. Gelfand - Houston TX
  • Assignee:
    Western Geophysical Company of America - Houston TX
  • International Classification:
    G01V 140
    E21B 4700
  • US Classification:
    367 35
  • Abstract:
    An acoustic borehole tool consists of two components: A first component containing power supplies, signal processing and control electronics and a sidewall locking mechanism. A second component includes a seismic sensor and a clamping device for pressing the sensor against the sidewall of a borehole. The weight of the second component is a small fraction of the weight of the first component so that the force exerted by the clamping device is less than a preselected limiting value and so that the clamping force/mass ratio may reach large value without danger of destroying the borehole.

  • Noise-Attenuating Streamer-Cable Bulkhead

  • US Patent:
    46944362, Sep 15, 1987
  • Filed:
    May 29, 1984
  • Appl. No.:
    6/615086
  • Inventors:
    Valery A. Gelfand - Houston TX
  • Assignee:
    Western Geophysical Company of America - Houston TX
  • International Classification:
    G01V 138
  • US Classification:
    367 20
  • Abstract:
    A plurality of streamer-cable bulkheads mounted within a streamer cable in cascade for radially scattering tube-wave noise from a streamer-cable. Each bulkhead consists of an annular body with conical surfaces converging at a desired angle, extending outwards from both ends of the annular body. An axial hole and a plurality of off-axial holes extending through the bulkhead for receiving therethrough, electrical conductors and stress members respectively. Noise traveling within the tube in a waveguide mode, impinges upon the conical surfaces of the cascaded bulkheads, and is reflected out of the streamer-cable jacket.

  • Method For Seismic Lithologic Modeling

    view source
  • US Patent:
    46791744, Jul 7, 1987
  • Filed:
    Feb 4, 1986
  • Appl. No.:
    6/825698
  • Inventors:
    Valery A. Gelfand - Houston TX
  • Assignee:
    Western Geophysical Company of America - Houston TX
  • International Classification:
    G01V 130
  • US Classification:
    367 73
  • Abstract:
    A method of seismic exploration of the subsurface of the earth. Seismic reflection data are gathered in a selected area. The seismic data are combined with available non-seismic data to define an initial two-dimensional lithologic model. Based upon the initial model, a set of synthetic seismic data is generated. The degree of correspondence between the set of synthetic reflection data and the gathered seismic data is determined. The initial model-parameters are systematically perturbed during a series of iterations until a desired degree of correspondence has been achieved, resulting in a final lithologic model.
