Estimating drill noise source signature using an array of seismic receivers located near the source

摘要

A first array of seismic receivers 52 and a second array of seismic receivers 56 simultaneously receiving drill 74 noise seismic energy produced as a wellbore 76 is drilled. The first array 52 is closer to the source of the drill noise seismic energy than the second array 56. The first array 52 may be located in a borehole 54 or, in the case of a marine seismic survey, suspended beneath a buoy or on the seabed. The second array 56 may be on the earth's surface, or towed behind a vessel or on the seabed. The drill noise source signature is estimated from the seismic data acquired by the first array 52 and used as a deconvolution operator when processing the data acquired by the second array 56.
