Walter R. Turpening has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Cross-well connectivity mapping including separation of compressional and shear wave energy
    Patent number: 6009043
    Abstract: A method of determining the continuity of earth formations between wellbores by analyzing seismic energy imparted to the formations. The energy is imparted to the formations at a plurality of depths in one wellbore and is received at a plurality of depths in another wellbore. Compressional and shear components of the seismic energy received in the other wellbore are separated. A frequency spectrum is determined for the compressional component and the shear component of the seismic energy at each selected depth. Common imparted depth stacks of the compressional components and shear components are assembled at the depths at which the seismic energy is imparted. Common received depth stacks of the compressional components and the shear components are assembled at the selected depths at which the energy is received.

  • Earth reaction seismic source
    Patent number: 5360951
    Abstract: A source for emission of seismic energy waves into subsurface earth formations is provided with electrically energizable signal generators mounted between two plate members. One of the plate members is anchored to the earth surface and the other rests on and is coupled with the earth surface. The source is easily movable between shotpoint locations and provides controllable seismic signals of improved bandwidth and quality.
