BERGEN, Norway — ONGC has commissioned Shearwater GeoServices Holding to acquire a six-month ocean-bottom node (OBN) survey offshore India.
The company will deploy its Pearl node technology onboard the SW Tasman, a vessel designed for advanced seismic source and dual-ROV operations.
Pearl employs micro-electromechanical systems to detect low frequencies generated by source technology such as the company’s Harmony low-frequency source.
The system, Shearwater claims, provides larger and denser spreads, longer listening times and better signals, with up to 150 nodes for each trip compared to an industry standard of 20-30.

Shearwater says Pearl is the world’s smallest and lightest ocean bottom seismic node.

With Pearl nodes, Shearwater says users get up to six times more nodes in a single ROV load and the technology is 30% more time efficient to deploy for 150 continuous recording days.
