Abstract:
1. A method comprising: deploying seismic sensors to perform a seismic survey, wherein at least one of the seismic sensors is associated with a seismic unit, and the seismic unit is adapted to perform a self-test within the unit to determine an associated sensor transfer function during the deployment of the seismic sensor; determining an associated operator to apply to seismic data acquired by each of the seismic sensors in the seismic survey based at least in part on a frequency dependent variation between the associated sensor transfer function and a nominal response for the seismic sensor; processing the seismic data, comprising applying the associated operators to the seismic data; communicating the seismic data and second data indicative of the determined associated sensor transfer operator from the seismic unit; and recording the seismic data and the second data.
