Abstract

In the last few years, the interest towards the utilization of Dispersed Source Arrays (DSAs) in seismic acquisition has considerably grown. The proposed approach offers a wide range of practical advantages, while no physical constraint restrains us from utilizing diverse sources with different spectral properties during seismic surveys. As a consequence, the use of simple autonomous source boats with airgun arrays of different sizes or marine vibrators producing sweeps with different frequency ranges (in marine) and simple autonomous source trucks (on land) becomes a practical proposition in DSA acquisitions. This concept could give to the system additional operational flexibility and facilitate the automation of seismic data collection. Therefore, with this study we intend to investigate the advantages that DSAs and system decentralization would bring to seismic data acquisition. Although the main focus of this research is on the marine environment, a generalization to the applications of the method on land is possible. Preliminary examples show that it is possible to produce valid migration outputs from 3D decentralized DSA data.
