  2. Reflection seismology - Wikipedia

    en.wikipedia.org/wiki/Reflection_seismology

    Reflection seismology (or seismic reflection) is a method of exploration geophysics that uses the principles of seismology to estimate the properties of the Earth's subsurface from reflected seismic waves. The method requires a controlled seismic source of energy, such as dynamite or Tovex blast, a specialized air gun or a seismic

  3. Exploration geophysics - Wikipedia

    en.wikipedia.org/wiki/Exploration_geophysics

    Exploration geophysics is an applied branch of geophysics and economic geology, which uses physical methods at the surface of the Earth, such as seismic, gravitational, magnetic, electrical and electromagnetic, to measure the physical properties of the subsurface, along with the anomalies in those properties.

  4. USArray - Wikipedia

    en.wikipedia.org/wiki/USArray

    A major goal of USArray was to collect detailed seismic images of the North American lithosphere. The data collected from USArray was integrated with geologic observations made on the Earth's surface to help determine the geologic history of North America, as well as to better understand that geologic processes that are at work today.

  5. J. Clarence Karcher - Wikipedia

    en.wikipedia.org/wiki/J._Clarence_Karcher

    To honor Karcher's contribution to the use of geophysical methods in oil exploration, the J. Clarence Karcher Award [10] is given in recognition of significant contributions to the science and technology of exploration geophysics. In 1976, Karcher received the Anthony Lucas Medal from the American Institute of Mining and Metallurgical and ...

  6. Geophysical survey - Wikipedia

    en.wikipedia.org/wiki/Geophysical_survey

    There are many methods and types of instruments used in geophysical surveys. Technologies used for geophysical surveys include: [1] Seismic methods, such as reflection seismology, seismic refraction, and seismic tomography. This type of survey is carried out to discover the detailed structure of the rock formations beneath the surface of the Earth.

  7. Seismic data acquisition - Wikipedia

    en.wikipedia.org/wiki/Seismic_data_acquisition

    For land acquisition, different types of sources may be used depending on the acquisition settings. Explosive sources such as dynamite are the preferred seismic sources in rough terrains, in areas with high topographic variability or in environmentally sensitive areas e.g. marshes, farming fields, mountainous regions etc. [4] Such type of sources needs to be buried (coupled) into the ground in ...

    en.wikipedia.org/wiki/Eugene_McDermott

    Eugene McDermott (February 12, 1899 - August 23, 1973) [1] was an American engineer and geophysicist who co-founded Geophysical Service Incorporated (GSI) in 1930 and later its parent company Texas Instruments in 1951. [2]

  9. Seismic migration - Wikipedia

    en.wikipedia.org/wiki/Seismic_migration

    A form of migration is one of the standard data processing techniques for reflection-based geophysical methods (seismic reflection and ground-penetrating radar) The need for migration has been understood since the beginnings of seismic exploration and the very first seismic reflection data from 1921 were migrated.
