Method for survey design including configuring electrodes to reduce
near-surface noise in the seismic response from an electroseismic survey
of a subterranean formation. Different embodiments of the invention
include (1) selective measurement of the surface noise to remove it from
the data; (2) suppressing surface noise generation by reducing electric
fields in the vicinity of some of the electrodes; (3) creating source
signature differences between the near-surface seismic response and the
deep response enabling the near surface response to be removed in data
processing; (4) applying an external near-surface magnetic field to
modulate the near-surface seismic response, enabling it to be removed in
processing; and (5) constructing a partial Faraday cage to shield a
near-surface region from fields generated by the electrodes.
