In hydrocarbon exploration, innovation is essential for improving efficiency and sustainability, particularly in node operations. By incorporating Autonomous Underwater Vehicles (AUV) and utilizing the latest machine learning advancements, ocean bottom node (OBN) deployment and recovery can be far more efficient. This will make the high-quality data from OBN more accessible to the broader industry.   

PXGEO’s MantaRay is based on the Saab Sabretooth AUV. The Sabretooth platform has been operating and developed for over a decade by the Swedish defense contractor. It is a fully electrically powered vehicle designed for autonomous operations and handling extensive payloads. Its reliance on electrical systems improves reliability and reduces maintenance. Enhanced with a variable buoyancy system, the MantaRay is neutrally buoyant and can operate in depths ranging from 5 to 3,000 meters and achieve speeds of up to five knots.   

Using stereographic cameras and AI-powered 3D visual recognition, MantaRay ensures precise node placement and retrieval during its pre-programmed mission. Operational modeling has shown that MantaRay can reduce survey duration by 50%, resulting in faster seismic data delivery while minimizing operational exposure and environmental impact. 

These technological advancements allow for faster, more efficient, and environmentally friendly operations, creating a promising future for ocean bottom node seismic.
