Optimal selection of locations for sensors in a seismic survey has been a long-standing issue for geophysicists.If we 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 us to make do with orders of magnitude fewer sampling points than Nyquist theory would dictate.The field of Compressive Sensing(CS)provides a new theory for non-uniform sampling that allows for using significantly fewer sensors than current practice in seismic exploration.We describe the application of CS concepts to seismic survey design.
