Title:
METHODS AND APPARATUS OF SOURCE CONTROL FOR SYNCHRONIZED FIRING OF AIR GUN ARRAYS WITH RECEIVERS IN A WELL BORE IN BOREHOLE SEISMIC
Document Type and Number:
WIPO Patent Application WO/2009/112917
Kind Code:
A3
Abstract:
Methods and apparatus for generating borehole seismic surveys are disclosed. The - methods and apparatus enable more accurate surveys than previous surveying systems. In some embodiments, firing of remote seismic sources is synchronized with data recording in a borehole. In some embodiments, the synchronization is based on a universal time standard. In some embodiments, GPS positioning technology is used to predict firing times and synchronize firing times with downhole and surface recording.
