As the first large‐scale, deep water seismic acquisition survey to obtain data from autonomous nodes, the survey fostered innovations in node manufacturing, node deployment and survey design. Deployment equipment included a back deck designed to minimize human intervention, two remotely operated vehicles (ROVs), specially designed ROV skids and an advanced navigation system. Intensive modeling provided an assessment of optimal node spacing, node layout grid and source offsets. Further considerations of operational and investment costs, geophysical criteria, and processing requirements led to a final survey design of approximately 6 nodes/km2 in a hexagonal sampling pattern, divided into two patches. The Atlantis OBS node project successfully took a complex technology directly from inception to deep water application, bypassing the gradual progression from shallow to deep water implementation that has been standard for most deep water technologies.Permalink: https://doi.org/10.1190/1.2370133FiguresReferencesRelatedDetailsCited ByReferences4 February 20204D compliant processing of OBN data: Case histories of the Atlantis and Thunder Horse fields, deepwater Gulf of MexicoKenneth Craft, Carsten Udengaard, Chuck Keller, Michael Harkness, David Gore, Samarjit Chakraborty, Jean-Paul Van Gestel, Qingsong Li, and Pierre Olivier Ariston1 September 2016References29 April 2012Enhanced prestack depth imaging of wide-azimuth data from the Gulf of Mexico: A case historyXuening Ma, Bin Wang, Cristina Reta-Tang, Wilfred Whiteside, and Zhiming Li22 November 2011 | GEOPHYSICS, Vol. 76, No. 5Orthogonal wide azimuth surveys: Acquisition and imagingSimon Baldock, Cristina Reta‐Tang, Brad Beck, Wei Gao, Elayne Doue, and Steve Hightower8 August 2011Enhanced pre‐stack depth imaging of wide‐azimuth data from the Gulf of Mexico: a case historyX.
