The future of Nodes Acquisition

The purpose of the EAGE Local Chapter Paris is to Engage with the multicultural and multidisciplinary geoscience network in Paris and internationally within the EAGE to promote young talent and innovation and to foster the recognition of the geoscientific profession in the community at large.The EAGE Local Chapter Paris Board is composed by:President: Laura MozgaVice-President: Emilio Darriba LeguenSecretary: Pedram MasoudiTreasurer: Guillaume HeninHead of Events: Hayet SerradjiHead of Company Relations: Soraya BornazHead of Communications: Pierluigi NichiloHead of Students Relations: Elias Macuacua

EAGE Local Chapter Paris

Online Event organized by EAGE Local Chapter Paris

Ocean bottom nodes offer unrivalled possibilities in terms of seismic velocity model building and imaging. However, this type of acquisition is more costly than conventional marine acquisition. This is due to the complex marine operations for node deployment and retrieval.Our 3 speakers will introduce you to the new technologies deployed to reduce survey durations and optimize the cost of this type of acquisition while preserving end data quality. Speakers: Ted Manning (BP), Fabio Mancini ( Blue Ocean Seismic Services), Kris Ellis (PXGEO) Agenda On BP’s vision for Sustainable Seismic, and the key complementary technologies requiredby Ted Manning (BP)This talk will summarise how innovation and advances in data acquisition technology will create massive subsurface imaging transformation over the next few years. New technology breaks the project management mantra of ‘cost, time, quality: choose two’. By accelerating the development and uptake of several complementary technology areas, we will show how to dramatically improve seismic operational performance, recorded data quality, operational safety exposure, and operational environmental impact. Taken as a whole, we refer to this outcome as Sustainable Seismic. Key technology areas include: 1) uncompromised wavefield sampling, 2) marine autonomous vessels and remote crews, 3) hybrid swarm autonomous receivers (robotics), 4) smaller autonomous sources, and 5) associated data driven processing algorithms and workflows. These solutions will also apply to clean energy models such as subsurface storage monitoring (Hydrogen and CCS) as well as near surface imaging (shallow hazards and windfarm foundations). Development of a novel seismic acquisition system based on fully autonomous ocean bottom nodesby Fabio Mancini (Blue Ocean Seismic Services)In this talk we will show the development of a novel seismic acquisition system which utilises a fleet of fully autonomous underwater vehicles (AUVs) as ocean bottom nodes OBNs. The objective is to eliminate the reliance on remotely operated vehicles (ROVs) or ropes for deployment, making ocean bottom seismic acquisition significantly more efficient and cost-effective.We will show the results from seismic field trials, where we assessed our units’ ability to record good seismic data. We will also present the outcome of multiple field trials where we assessed the unit’s in-water capabilities. These tests consisted of simulating a seismic acquisition cycle, including flight to target, landing, (passive) data recording, take-off and repositioning to a new target without emerging. Unlocking the full potential of OBN seismic with a new generation of autonomous vehiclesby Kris Ellis (PXGEO)Starting with a brief history of ocean bottom node evolution over time, along with present-day capabilities, Kris will then take a deep dive into MantaRayTM, a hovering autonomous underwater vehicle engineered to deploy and recover ocean bottom nodes with minimal impact to the ocean floor.Looking at efficiencies gained, which will reduce node deployment and retrieval times by up to 50%, we will aim to provide as much information on what PXGEO envision the future of node acquisition will entail.
