Efficient algorithm for wavefield reconstruction and 3D receiver-side deghosting
Generalized matching pursuit (GMP) performs high-fidelity wavefield reconstruction and full 3D receiver-side deghosting of multimeasurement marine streamer data simultaneously in a single, efficient algorithm. It enables us to extend the usable bandwidth of your data while interpolating between acquisition cables.
Deghosts and interpolates your data in one step
GMP relates the pressure (P), vertical (Z), and crossline (Y) measurements from the streamer to the unknown deghosted pressure. The input data is iteratively decomposed into its constituent components or basis functions until the original signal is described. Once the basis functions are calculated, the pressure wavefield can be reconstructed at any point within the streamer spread, resulting in a continuous, reliable representation of the deghosted wavefield in all directions.
