TGS and Viridien Launch Laconia Phase III Ocean Bottom Node Survey in Gulf of America
Key Insights
TGS (search) and Viridien (search) have commenced Laconia Phase III, a large-scale ocean bottom node survey spanning approximately 150 OCS blocks in the Gulf of America's central Keathley Canyon area.
The project utilizes advanced seismic technologies including TGS (search)' ZXPLR™ nodes and Sercel (search)'s Tuned Pulse Source to deliver ultra-long offset data with enhanced low-frequency imaging capabilities.
The survey targets the increasingly attractive Paleogene play following recent industry success with 20k technologies, with initial products scheduled for delivery in Q1 2026.
TGS (search), a global leader in energy data and intelligence, has partnered with Viridien (search) to launch Laconia Phase III, an advanced ocean bottom node (OBN) survey in the Gulf of America. The project, which began acquisition in May 2025, represents the latest phase in the large-scale Laconia survey program and spans approximately 150 OCS blocks in the central Keathley Canyon area.
Advanced Seismic Technology Deployment
The Laconia Phase III survey employs cutting-edge seismic acquisition technology, combining TGS (search)' ZXPLR™ nodes with Sercel (search)'s Tuned Pulse Source (TPS™). The TPS technology serves as a low-frequency broadband marine seismic source designed to enhance geophysical imaging clarity by improving low-frequency, deep penetrating sound energy. This technological combination aims to deliver Ultra Long Offset OBN data that will significantly improve subsurface clarity in the targeted region.
Viridien (search)'s Subsurface Imaging experts will process the acquired data using the company's advanced proprietary technologies, including Elastic Full-Waveform Inversion (E-FWI) and Reverse Time Migration (RTM) imaging capabilities. These sophisticated processing techniques are designed to deliver best-in-class seismic data to support both exploration and development activities in the region.
Strategic Focus on Paleogene Play
The survey specifically targets the Paleogene play, which has become increasingly attractive following recent industry success in implementing 20k technologies. The central Keathley Canyon acreage covered by Laconia Phase III is anticipated to be highly sought after in future lease sales by companies focusing on this geological formation.
The project builds upon the success of Laconia Phases I and II, which were launched by Viridien (search) in July 2024. According to Sophie Zurquiyah, CEO of Viridien, early results from Laconia Phase I have already attracted considerable industry attention, demonstrating the effectiveness of the advanced imaging capabilities employed in the program.
Project Timeline and Industry Support
The Laconia Phase III OBN acquisition will continue through Q3 2025, with delivery of initial products scheduled for Q1 2026. The project has secured industry funding, indicating strong market confidence in the survey's potential value.
"TGS (search) remains committed to supporting the energy industry with the highest quality seismic solutions," stated Kristian Johansen, CEO of TGS. "Laconia Phase III represents another significant step forward in our ability to deliver advanced data products in one of the world's most important offshore regions."
Zurquiyah emphasized the collaborative approach, noting that "by teaming up with TGS (search) on Laconia Phase III, we are leveraging our respective strengths to deliver a high-impact dataset in one of the world's most prospective offshore regions."
Market Position and Technology Integration
The partnership leverages TGS (search)' position as a global leader in energy data and intelligence, combined with Viridien (search)'s advanced technology capabilities as a digital and Earth data company. The collaboration represents a strategic combination of leading-edge OBN acquisition and imaging technologies designed to unlock further potential in the Gulf of America's offshore regions.
The success of the Laconia OBN program demonstrates the value that technological innovation brings to offshore exploration, with the advanced seismic data expected to provide tremendous value to customers operating in this critical energy region.
