Title:
VSP PATTERN RECOGNITION IN ABSOLUTE TIME
Document Type and Number:
WIPO Patent Application WO/2009/062040
Kind Code:
A3
Abstract:
A procedure to determine VSP-WD (Vertical Seismic Profiling - While Drilling) first breaks in absolute time is described. By combining a seismic surface source and firing complex seismic pattern unique in time (with a highly accurate surface - downhole time reference system), an automatic downhole procedure for first break detection on the downhole data, even under harsh conditions (low signal to noise ratio), is established.
