MASS OBS Acquisition

Magseis offers large scale and step-changing efficiencies to Ocean Bottom Seismic acquisition services to clients worldwide using its proprietary Marine Autonomous Seismic System (MASS).
MASS consists of ultra-compact 4C sensor capsules, fully automated handling systems and data download. The lightweight nodes enable us to carry unlimited number of nodes and increase the size of the receiver spread deployed on the seabed. The automated handling systems significantly improve operational efficiencies by deploying and retrieving faster and superior logistics of equipment. This means that we dramatically can reduce the time required acquire OBS surveys and reduce the overall cost.

Magseis’ MASS node is depth rated from 0-3,000m water depth, allowing uniform node technology across various water depths.

The full range of capabilities of the MASS, has been proven over 4 years of operations and has demonstrated its robustness and efficiency gains.

The company has mainly been operating on producing fields for monitoring purposes, but have also seen increased interest for OBS for exploration purposes. In 2015, Magseis acquired its first multi-client survey in the Barens Sea, where they provided full-azimuth data and using the s-wave for imaging below the famous gas-cloud “Tåkehavet” (“Sea of Fog”). As the capacity and node count increases, it will be easier to deploy larger spreads on the seabed, which in turn will enable reduced cost and trigger OBS as the right tool in the toolbox for exploration activities.
