Abstract:
A geologic survey system includes a plurality of acoustic sources spaced at intervals over a target area of a terranean surface. Each of the plurality of acoustic sensors is configured to generate a seismic energy wave. The system also includes a plurality of acoustic sensors positioned in a plurality of boreholes formed in a geologic formation, where the boreholes have a depth sufficient to reach a geologic datum. The system also includes a control system communicably coupled to the plurality of acoustic sensors and configured to perform operations including receiving, from the plurality of acoustic sensors, data associated with reflected acoustic signals generated by the plurality of acoustic sources and received by the plurality of acoustic sensors; determining, based on the received data, a subsurface topology of the geologic formation; and generating a subsurface model of the geologic formation based on the determined subsurface topology.

Claim (Index 21):
The computer-implemented method of  claim 20 , wherein processing the data associated with reflected acoustic signals in the time imaging model comprises:\n estimating static corrections of the data associated with reflected acoustic signals; partitioning the estimated static corrections into a short wavelength and a long wavelength; attenuating noise from the estimated static corrections of the data associated with reflected acoustic signals; shifting the estimated static corrections of the data associated with reflected acoustic signals to a plurality of pre-defined intermediate depth levels based on vertical timeshifts measured from the plurality of boreholes; stacking common gathers from each of the plurality of acoustic sensors to generate a plurality of supergathers, each of the supergathers having an improved signal-to-noise ratio; at each of the plurality of pre-defined intermediate depth levels:\n sorting the supergathers to a common depth point, \n applying the short-wavelength static corrections, and \n estimating normal moveout velocity and applying a normal moveout correction and stack; \n applying the long-wavelength static shifts to the geologic datum; stacking the plurality of stacks generated from the plurality of pre-defined intermediate depth levels into a final stack; and performing a post-stack time migration.
