Detection of Open Fractures with Vertical Seismic Profiling
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1984-01-01)
In Vertical Seismic Profiling surveys tube waves are generated by compressional waves impinging on subsurface fractures or permeable zones. The problem of generation of these waves by a non-normal incident P wave for an ...
Detection Of Subsurface Fractures And Permeable Zones By The Analysis Of Tube Waves
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1983)
In Vertical Seismic Profiling tube waves are generated by compressional
waves impinging on subsurface fractures or permeable zones. The amplitude of
tube waves is dependent upon the formation permeability, the length of ...
