    后一万能码 2期内中 www.qgqx.net Although geophysical techniques focus primarily on the exploration of  natural resources,they are also applied for environmental and urban civil engineering investigations. We offer a wealth of knowledge and experience to ensure that the most appropriate and best technology CGG has to offer is employed.

    The table below is set out in order of depth of investigation (from a few centimeters to several kilometers).

    Methods

    Applications

    Ground-Penetrating Radar
    • Underground networks (sewers, aqueducts, miscellaneous piping), shallow cavities
    • Pollution by hydrocarbons, determining the nature of waste material
    • Sounding structures, routing pipelines
    • Fractures
    Microgravity
    • Shallow voids, limits of refuse tips, quality of foundations
    • Massive ore bodies
    Ground-Based Magnetics
    • Eruptive rocks, faults
    • Mines
    • Environment: detection of buried ferro-magnetic objects
    Seismic Tomography
    • Foundations and injections
    • Fracturing
    • Mining and oil exploration (static corrections for reflection seismic)
    Electric Profiling and Electromagnetics with
    a mobile, short-distance transmitter
    • Salt pinch-outs, faulted or polluted zones (salt)
    • Thickness of weathered and decayed rock on the basement, lithological contacts.
    Borehole Logging
    • Hydrogeology: lithology and stratigraphy, fracturing, porosity, evaluation of cementing
    • Mines: lithology (density, porosity)
    • Civil Engineering: fracturing
    • Hydrocarbons: static corrections and synthetic seismogram for seismic
    Refraction Seismic
    • Thickness of the overburden
    • Locating the water table
    • Fracturing, faults
    • Studies of household or industrial waste dumps
    Electrical Sounding
    • Geological exploration, water quality, large basin structure
    High-Resolution Reflection Seismic
    • Location of specific structures for mineral water, drinking water, geothermal springs
    • Mining exploration (coal, pyrite, salt, potash)
    • Tunnel or gallery routing
    • Studies of underground storage sites
    Magnetotellurics
    • Structural or stratigraphic surveys in mining, hydrocarbon and geothermal exploration
    Gravity
    • Structural surveys: basins, domes, fault blocks, etc.
    • Detection of solid ores: barite, sulphides, coal, salts, etc.
