• Potential of 3D vertical seismic profiles to characterize ...

    Vertical Seismic Profile [4] A highresolution seismic imaging technique employed in industry is the vertical seismic profile (VSP). It was used in scientific ocean drilling for 1D and 2D experiments [Stephen et al., 2007] by lowering single or multiple geophones in a drill hole that receives signals from a surface source. Coverage is obtained by lowering the recording array to various ...

  • Seismic Resolution: Vertical and Horizontal

     · Seismic Resolution: Vertical and Horizontal Overview. Seismic resolution is the ability to distinguish between two features from one another. There are two types of seismic resolution, being vertical and horizontal. Vertical resolution determines the thickness of the beds, such as two close seismic responds corresponding to different depth levels. Vertical resolution represents the distance ...
