Shearwater Geoservices launches Ghana deepwater seismic survey

Shearwater Geoservices has secured the contract to carry out Ghana's first deepwater Ocean Bottom Node (OBN) seismic survey in the Jubilee and TEN fields, operated by Tullow Oil and its partners

This marks a significant milestone for offshore exploration in Ghana. The two-month survey is set to begin in the final quarter of 2025.

This project follows Shearwater's successful deployment of the SW Tasman vessel and Pearl node OBN platform in other West African countries, including Côte d'Ivoire and Angola. Since late 2024, these platforms have been instrumental in conducting OBN surveys across the region, starting with Côte d'Ivoire, and continuing with surveys in Angola.

Irene Waage Basili, CEO of Shearwater, said, "These projects demonstrate Shearwater’s role in pioneering new technology in new regions, delivering operational excellence and industry-leading survey efficiency and data quality. By delivering the first OBN project in Ghana and other surveys across this part of Africa, we are opening new geophysical frontiers – combining precision, innovation and commitment to responsible resource exploration."

The Jubilee and TEN fields have been at the heart of Tullow's operations for nearly 20 years. This first deepwater OBN survey is expected to improve reservoir imaging, offering deeper insights for future field development and production strategies. It follows a previous streamer survey carried out by Shearwater over the same fields earlier in 2025.
