Seismic Prospecting - BRANTAX

2011-4-6  Seismic prospecting is by far the most important geophysical technique in terms of expenditures and number of geophysicists involved. Its predominance is due to high accuracy, high resolution, and great penetration. Seismic methods are important in groundwater searches and in civil engineering, especially to measure the depth to bedrock in connection with the construction of large

Seismic Prospecting SpringerLink

Abstract. Seismic prospecting has its basis in the classical physical principles of transmission, reflection, refraction, and scattering of elastic waves in a layered solid half-space. The great increase in application of the methods and the continual effort to improve them since 1925 have resulted in elaboration and refinement of instruments ...

Three dimensional seismic prospecting method - Phillips ...

A 3-D seismic prospecting method is provided which employs an areal array of sources and receivers by which seismic traces are generated. The areal array is segregated into a plurality of shells and angularly separted sections from which a preselected number n 1 of source-receiver pairs are selected for a particular common midpoint. By means of the shells and sections, the source-receiver ...

Three-Dimensional Seismic Ahead-Prospecting Method

The tunnel seismic ahead-prospecting method is used to estimate adverse geology ahead of the tunnel face. Accurately realizing this geology helps to guarantee safety during construction using a tunnel boring machine (TBM). The paper proposes a three-dimensional (3D) seismic ahead-prospecting method by optimizing a filtering method and an ...

Among all forward geological prospecting methods, the seismic detection method is widely applied. However, due to the characteristics of the tunnel and the complexity of the geological conditions, the seismic wavefield is complicated. Carrying out a more realistic forward modeling method is vital for fully understanding the law of seismic wave ...

SEISMIC PHASE UNWRAPPING: METHODS, RESULTS,

Abstract Six known methods of seismic phase unwrapping (or phase restoration) are compared. All the methods tested unwrap the phase satisfactorily if the initial function is a simple theoretical wavelet. None of the methods restore the phase of a synthetic trace exactly. An initial validity test of the phase‐unwrapping method is that the sum of the restored wavelet phase spectrum and
