“…It is by now accepted that the way forward for seismic data acquisition will be to acquire data using dense sources and receivers in order to obtain high‐resolution broadband seismic data (Blacquiere and Berkhout ; Ourabah et al. ). Currently large acquisition land seismic crews record over 60K+ live channels per shot which corresponds to roughly 6Tb of data acquired per day.…”

“…Widely scalable Mobile Underwater Sonar Technology (WiMUST) is another initiative where a collaboration between industry and academia aims at designing a number of cooperative autonomous marine robots that could significantly improve the performance of geophysical and geotechnical marine surveys. It is by now accepted that the way forward for seismic data acquisition will be to acquire data using dense sources and receivers in order to obtain high-resolution broadband seismic data (Blacquiere and Berkhout 2013;Ourabah et al 2014). Currently large acquisition land seismic crews record over 60K+ live channels per shot which corresponds to roughly 6Tb of data acquired per day.…”

Although narrow‐azimuth towed‐streamer data provide good image quality for structural interpretation, it is generally accepted that for wide‐azimuth marine surveys seabed receivers deliver superior seismic reflection measurements and seismically derived reservoir attributes. However, seabed surveys are not widely used due to the higher acquisition costs when compared to streamer acquisition. In recent years, there have been significant engineering efforts to automate receiver deployment and retrieval in order to minimize the cost differential and conduct cost‐efficient seabed receiver seismic surveys. These engineering efforts include industrially engineered nodes, nodes on a rope deployment schemes and even robotic nodes, which swim to and from the deployment location. This move to automation is inevitable, leading to robotization of seismic data acquisition for exploration and development activities in the oil and gas industry. We are developing a robotic‐based technology, which utilizes autonomous underwater vehicles as seismic sensors without the need of using a remotely operated vehicle for deployment and retrieval. In this paper, we describe the autonomous underwater vehicle evolution throughout the project years from initial heavy and bulky nodes to fully autonomous light and flexible underwater receivers. Results obtained from two field pilot tests using different generations of autonomous underwater vehicles indicate that the seismic coupling, and navigation based on underwater acoustics are very reliable and robust.
