Nondestructive downhole seismic vibrator source and processes of utilizing the vibrator to obtain information about geologic formations

摘要

The invention relates to a nondestructive downhole seismic source capable of generating SV-waves, SH-waves, and P-waves alone or in combination to determine information about a surrounding geologic formation. The invention also includes processes of performing crosswell tomography and reverse vertical seismic profiling. The invention also includes a means and process to carry out in hole seismic logging operations.
