Orientation and calibration of acoustic vector sensor arrays

摘要

The specification describes a system and related method for determining the orientation of acoustic vector sensors installed in well bores that utilizes acoustic signals of known orientation in the casing to determine the orientation of the acoustic vector sensors. The acoustic vector sensors may be part of a string of acoustic sensors for acoustic or seismic surveys of subsurface formations, or may also be coupled to downhole devices for which orientations need to be know.
