Demonstrating deployment of autonomous seabed seismic nodes for multi-component seismic data

Offentlig prosjektsammendrag

The project demonstrates a technology for reservoir monitoring. It uses nodes that are planted into the seabed for improved measurement accuracy of the seismic data. Nodes are much smaller (a fifth of the size of existing planted nodes), have advanced features (such as an advanced positioning system), and has a customized ROV deployment system designed to minimize ship time. The result is high quality at low cost. A better understanding of the reservoir means that you are able to better position and plan producer and injector wells for improved oil and gas production. Especially in marginal fields, it is important to lower risk and cost. Also, high quality data is important for monitoring carbon storage, which could be a major activity on the NCS in the coming decades. The technology is patented by 4CNode (Norwegian Patent no. 339718 and US patent no. 15/764606). 4CNode collaborates with InApril that manufactures the nodes. It also cooperate with Norbit on node communication and positioning, and Deepocean on ROVs and subsea .operations. In addition there is a cooperation ConocoPhillips on testing the nodes on the Ekofisk Field
