Optimal selection of locations for sensors in a seismic survey has been a long-standing issue for geophysicists. If they could sample the earth at two points per wavelength or better in all dimensions according to Nyquist sampling theory, design would not be an issue. The reality of limited access and funding requires geophysicists to make do with orders of magnitude fewer sampling points than Nyquist theory would dictate. Compressive sensing (CS) provides a new theory for nonuniform sampling that allows the use of significantly fewer sensors than current practice in seismic exploration would require. CS concepts can be applied to seismic survey design.
