Abstract:
1. A method of acquiring seismic data from a subsurface region that contains a target sector of interest, comprising: (A) providing (i) information about the harmonic response for the target sector of interest and (ii) a seismic source; (B) controlling the seismic source to provide seismic waves through underground geologic strata to the target sector of interest in a narrowband selected on the basis of the information about the harmonic response for the target sector of interest, wherein the seismic waves provided by the seismic source comprise waves between 10 Hz and 250 Hz; (C) activating the seismic source so as to introduce seismic waves into the subsurface sector; and (D) sensing reflections of the seismic waves at a seismic receiver.
