System and method for seismic sensor response correction

A method for processing seismic data performed by a seismic data system, comprising:

• receiving signals representing seismic data recorded at a remote location;
• receiving, in conjunction with the signals, identification of a seismic sensor via which the signals were acquired;
• retrieving a sensor transfer function that corresponds to the seismic sensor, wherein the sensor transfer function indicates a response of the seismic sensor to a test signal having a predetermined wave shape, and wherein the response is based on a motion of the seismic sensor responsive to the test signal;
• generating based on the sensor transfer function and a reference transfer function, an inverse filter that when applied to the signals changes parameters of the signals to correspond to signals generated by a seismic sensor having the reference transfer function;
• and
• applying the inverse filter to the signals to conform the parameters of the signals to the reference transfer function.

A method for processing seismic data, comprising:

• as part of manufacturing test of a seismic sensor to be used for acquisition of seismic data:
• applying, using an impulse generation device, a test signal having a predetermined wave shape to the seismic sensor as part of a field test;
• recording a response of the seismic sensor to the test signal based on a motion of the seismic sensor responsive to the test signal;
• determining a sensor transfer function of the seismic sensor, wherein the sensor transfer function indicates the response of the seismic sensor to the test signal having the predetermined wave shape;
• storing the sensor transfer function for use by a seismic data processing system in generation of an inverse filter;
• as part of seismic data acquisition:
• acquiring seismic data via the seismic sensor;
• extracting the seismic data from a seismic data acquisition unit coupled to the seismic sensor;
• formatting the seismic data for transport to the seismic data processing system that is at a different location from the seismic data acquisition unit by providing identification of the seismic sensor for transport with the seismic data;
• as part of processing of the seismic data by the seismic data processing system:
• retrieving the sensor transfer function based on the identification of the seismic sensor;
• generating, based on the sensor transfer function and a reference transfer function, the inverse filter that when applied to the seismic data changes parameters of the seismic data to correspond to the seismic data being generated by a seismic sensor having the reference transfer function, wherein the reference transfer function is associated with a known accuracy;
• applying the inverse filter to the seismic data to conform the parameters of the seismic data to the seismic data being generated with the seismic sensor having the reference transfer function.
