Abstract

In Dispersed Source Arrays (DSA) acquisitions, traditional broadband seismic sources are replaced (or supported) with dedicated narrower band devices with different central frequencies, blended together to cover the entire temporal and spatial bandwidth of interest. The recent advances in unmanned systems technology and the improved operational flexibility enabled by the limited dimensions of most DSA devices may be beneficial to the data acquisition efficiency. In fact, with DSAs the use of relatively simple autonomous devices becomes a practical proposition for seismic surveys. In a marine environment we might consider employing several autonomous source boats at the same time, while on land a combination of autonomous source trucks of varied dimensions and designs is suggested. This abstract presents a real-time decentralized and automated approach to acquisition design in order to handle the larger number of sources simultaneously operational in the field. Additionally, using the Simultaneous Joint Migration Inversion (SJMI) technology it is possible to reliably recover time-lapse information despite the significant mismatch between baseline and monitor survey geometries introduced by the decentralized acquisition method.
