Vertical seismic profile surveying

Main objective of vertical seismic profile (VSP) and walkaway vertical seismic profile (WVSP) surveying is to verify geological structure of near-wellbore zone of exploration and production wells for designing of new production wells, including:

Downhole seismic survey objectives required for successful processing of onshore 2D/3D CDP seismic data are also addressed. Deployed downhole tool: AVSP-1M.
