The OBN seismic survey will cover the Jubilee and TEN fields operated by Tullow Oil, an independent energy company with operations in West Africa, and its partners, with the two-month project set to begin in the fourth quarter of 2025.

Tullow and its partners in the West Cape Three Points (WCTP) and Deep Water Tano (DWT) licenses that cover the Jubilee and TEN fields recently got an extension enabling the fields to remain in production until 2040.

According to Shearwater, the contract follows the use of the SW Tasman and Pearl node platform in Côte d’Ivoire and Angola, part of the company’s continuous operations offshore West Africa since late 2024.

This first OBN survey is expected to further enhance reservoir imaging, helping unlock deeper insights to inform field development and production strategies. Shearwater previously performed a streamer survey over the Jubilee and TEN fields early this year.

To remind, it was earlier today reported that the company secured a two-month OBN seismic survey in Angola with ExxonMobil’s affiliate Esso Exploration Angola Block 15 Limited.
