Shearwater has been selected to carry out the first deepwater ocean-bottom survey using node technology offshore Ghana, extending across the Tullow-operated Jubilee and TEN oil fields. This operation marks a new step in geophysical exploration in the West African region.
Node seismic technology in deep water
The survey will use seismic nodes distributed on the seafloor. seafloora methodology known as OBN (Ocean Bottom Node), recognized for its ability to provide high-resolution data in complex environments. This survey is expected to contribute to better visualization of the subsurface and more informed decisions in the management of the country’s energy resources.
The Norwegian company has maintained an active presence in the region since 2024, operating the SW Tasman and Pearl platforms for similar projects in Côte d’Ivoire and Angola. This operational continuity has allowed it to optimize processes and apply proven technologies in new offshore environments.
The project in Ghana will last an estimated two months and will begin in the last quarter of 2025. With this campaign, Shearwater seeks to strengthen its position as a leading provider of offshore seismic services, integrating technological precision and environmental responsibility in every phase of the survey.
The Jubilee and TEN fields have been mainstays of Tullow’s energy operations for nearly twenty years. The new node survey will complement previous seismic cable survey work. seismic cable conducted in early 2025, providing an additional layer of critical information for the next phases of development and production.
