The special properties of the Vertical Seismic Profile, which allows the separation of the upward and downward travelling components of the recorded waveform, provides a means of studying the acoustic response of the earth in detail. Deconvolution of the data in particular gives a clearer understanding of the mechanics of multiple reflections ...
The WST3 could be used in both checkshot and offset vertical seismic profile experiments. A remote seismic source was required for an offset survey, while a traditional check shot survey could be completed with existing equipment on the JOIDES Resolution. For each type of experiment, the deployment routine for the WST3 was approximately the same.
After seismic data is collected from the geophones and seismograph, specific profiles are constructed from wave velocities as a function of time. Examples of the vertical profiles constructed: Reflection Profile: Reflection involves a change in direction of waves when they bounce off a barrier. 2D Vertical Seismic Profile; Synthetic seismogram
Jul 27, 2021 · Wirelineconveyed tools and systems are used to acquire highresolution seismic images in and beyond the borehole. Many subsurface imaging problems cannot be solved without a 3D survey, and when a survey also needs to be performed in the borehole, the solution is 3D vertical seismic profile (VSP) technology.
1. n. [Geophysics] A type of vertical seismic profile in which the source is moved to progressively farther offset at the surface and receivers are held in a fixed loion, effectively providing a mini 2D seismic line that can be of higher resolution than surface seismic data and provides more continuous coverage than an offset VSP. 3D walkaways, using a surface grid of source positions ...
