Abstract

Summary

We study the optimized shot point and receiver placement problem for hybrid (cross-spread source and receiver) gathers by using the spectral characteristics of the surface waves. This is an acquisition geometry design problem where the objective is to find an optimized layout for a limited number of shot points and receivers such that the sampled data provide maximum information about the continuous-domain data. By using the SEG Advanced Modeling II Arid Model data, we show that surface waves have a unique structure that allows us to represent them with only a small number of both sensors and shot points. After reviewing the conditions for exact recovery of a continuous-domain signal from its sparse samples, we propose a method to design optimized geometries based on the compressed sensing principles. We expect that placing the shot points and receivers at the most informative locations will be beneficial to existing noise attenuation and interpolation algorithms.
