Vertical Seismic Profile in Horizontal Wells

The rudiments of vertical seismic profiling (VSP) and crosswell profiling (CWP) can thus be traced back more than 80 years to the date of this patent. In his analysis of how newly developing seismic methods could be used to map geological structures, Barton (1929) referred to Fessenden's earlier work and described possible uses of seismic ...

Offset, Walkway and 3D Vertical Seismic Profiles

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 ...

We used DAS to acquire a vertical seismic profile of a borehole located at a site in the southern United States. For acquisition, the fibre-optic cable was cemented outside of the casing between the borehole and the formation. In Figure 2, twenty sweeps from the zero-offset are correlated with the 10-100Hz pilot sweep and stacked.

VSP

In geophysics, vertical seismic profile (VSP) is a technique of seismic measurements used for correlation with surface seismic data. The defining characteristic of a VSP (of which there are many types) is that either the energy source, or the detectors (or sometimes both) are in a borehole.

vertical seismic profile

Aug 24, 2012· The vertical seismic component was a "new" thing added I think with the 1997 UBC. So if your 113 document is older than that it just may not have been a part of seismic design procedures. If it is more recent, I'm surprised it isn't included in the language of the code.
