METHOD FOR ACOUSTIC IMAGING OF THE EARTH'S SUBSURFACE USING A FIXED POSITION SENSOR ARRAY AND BEAM STEERING
First Claim
1. A method for seismic surveying, comprising:
- disposing a plurality of seismic sensors in a selected pattern above an area of the Earth'"'"'s subsurface to be evaluated;
repeatedly actuating a seismic energy source proximate the seismic sensors;
recording signals generated by the seismic sensors indexed in time with respect to each actuation of the seismic energy source; and
processing the recorded signals to generate an image corresponding to at least one point in the subsurface, the processing including stacking recordings from each sensor for a plurality of actuations of the source and beam steering a response of the seismic sensors such that the at least one point is equivalent to a focal point of a response of the plurality of sensors.

Abstract
A method for seismic surveying includes disposing a plurality of seismic sensors in a selected pattern above an area of the Earth'"'"'s subsurface to be evaluated. A seismic energy source is repeatedly actuated proximate the seismic sensors. Signals generated by the seismic sensors, indexed in time with respect to each actuation of the seismic energy source are recorded. The recorded signals are processed to generate an image corresponding to at least one point in the subsurface. The processing includes stacking recordings from each sensor for a plurality of actuations of the source and beam steering a response of the seismic sensors such that the at least one point is equivalent to a focal point of a response of the plurality of sensors.
