Shearwater Geoservices Holding AS has signed an ocean bottom node (OBN) project contract with TotalEnergies in Angola

The deepwater OBN survey will be conducted by the dual remotely operated vehicle (ROV)-equipped SW Tasman, the fit-for-purpose seismic node laying vessel which was converted in 2023, and SW Gallien as source vessel. A three-month-long operation approximately, the survey will commence in January 2025, with Shearwater deploying its compact high-endurance Pearl node in Block 32 over the Louro and Mostarda fields. The company has previously completed a 4D streamer survey in the region for TotalEnergies.

TotalEnergies keeps cementing its presence in Angola as the major reached a US$6bn final investment decision (FID) on the Kaminho Deepwater Development in May, marking the first major deepwater development in the Kwanza Basin.

Introducing deepwater OBN

Shearwater CEO, Irene Waage Basili, said, "We are very satisfied with the performance of our SW Tasman/Pearl OBN platform which has been in continuous operation since its introduction last year. We are pleased to see one more key client use this unique platform to introduce deepwater OBN to new areas of their operations."

Last month, the company has also secured a 4D seismic monitoring contract for the Jubilee field in Ghana, operated by Tullow Ghana Ltd.

STRYDE secures research partnerships

Onshore seismic solutions provider, STRYDE, has secured six new contracts with leading academic institutions to provide its solutions, including its newest offering, STRYDE Mini System, across the United States, Europe and Africa

These institutions are leveraging STRYDE’s cutting-edge technology to advance a variety of subsurface research initiatives in 2024, including geothermal well monitoring, geohazard identification for civil engineering, agritech, and mine development.

STRYDE’s new Mini System is a complete nodal seismic system specifically designed to enable small-scale seismic projects, including research projects for the academic sector. The company is known for providing the 'world’s smallest and lightest nodal seismic imaging system'.

High-density seismic capabilities

Mike Popham, STRYDE CEO, said, “Our agile and lightweight seismic system offers a rapid, cost-effective solution for seismic data acquisition.

“At STRYDE, we understand that high costs can hinder fundamental research and development, and I am proud that by further miniaturising our system, we’ve removed this barrier to innovation and can fulfil our mission of delivering high-density seismic capabilities across various industries. This advancement supports the next generation of geoscientists by equipping them with essential tools for conducting crucial research.”

A STRYDE user at Rice University said, "This survey was the highest in density and channel count ever conducted by our team. Achieving our desired trace density within our time and labour constraints would not have been possible without STRYDE's agile nodes.

“The lightweight nature of these nodes marked a significant advancement for us, allowing for high-density deployments on foot, even in rough terrain.”

STRYDE’s technology has been deployed on a global scale, where over 760,000 unique nodes have been delivered to the market, supporting over 260 projects, in over 50 different countries, across multiple sectors, including oil and gas, mining, civil engineering, and emerging renewables markets. One of the company's latest offerings include STRYDE Lens, an integrated in-field data processing service, which offers expedited access to interpretation-ready onshore subsurface images.
