Randomness in seismic survey acquisition

Abstract

Systems and techniques are provided for seismic acquisition operations. The displacements among activation positions of the seismic sources are random values or selected from a predefined list to accelerate progress to cover the area of interest. Regular or irregular perturbations (e.g., random values or selected from a predefined list) in a crossline direction are used for source line spacings and sail line move ups. The source line spacings are fixed or varied with respect to time during the seismic survey. The seismic sensors are spaced at regular or irregular intervals. Complete coverage are attained by performing interpolation techniques to the acquired seismic data. An image reconstruction from the collected seismic survey data, which are processed with compressive sensing techniques before the reconstruction, are generated based in part on an inversion technique or an imaging algorithm.
