The benefits of using autonomous nodes in a desert environment to efficiently achieve very high trace density seismic surveys with reduced HSSE risk and improved operational efficiency are increasingly being recognised by the industry. ADNOC, in partnership with BP, Rosneft and WesternGeco recently deployed 50,000 newly-developed ultra-light nodes (Manning et al, 2018) with simultaneous vibroseis source technology to acquire the densest ever seismic survey on land. The survey covered an area of 81km2 containing significant surface infrastructure and sand dunes.
The field trial had two main goals: first demonstrate the readiness of this new nodal system to acquire high quality seismic at full scale in a production-like setting; and second, to compare the data recorded by this new system to legacy data acquired by a conventional array geophone system and demonstrate the benefits of the former in terms of safety, operational efficiency and ability to image fine stratigraphic details at the reservoir.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
