 TGS and Viridien Announce Launch of Laconia Phase III OBN Survey in the Gulf of America

# TGS and Viridien Announce Launch of Laconia Phase III OBN Survey in the Gulf of America

OSLO, Norway (19 June 2025) - TGS, a global leader in energy data and  

intelligence, in collaboration with Viridien, an advanced technology, digital  

and Earth data company, today announced the commencement of Laconia Phase III in  

the Gulf of America. This latest phase in the large-scale Laconia ocean bottom  

node (OBN) survey program spans approximately 150 OCS blocks and follows the  

well-received Laconia Phases I and II launched by Viridien in July 2024.  

  

The program will be acquired by TGS and provide Ultra Long Offset OBN data using  

TGS' ZXPLR(TM) nodes and the Sercel Tuned Pulse Source (TPS(TM)). TPS is a low-  

frequency broadband marine seismic source that enhances geophysical imaging  

clarity by improving low-frequency, deep penetrating sound energy. The Laconia  

Phase III dataset, imaged by Viridien's Subsurface Imaging experts, will improve  

subsurface clarity, aiming to unlock further potential in the central Keathley  

Canyon area. This acreage is anticipated to be highly sought after in future  

lease sales for those companies targeting the Paleogene play, which is  

increasingly attractive following recent success in industry implementation of  

20k technologies. Leveraging Viridien's advanced proprietary Elastic Full-  

Waveform Inversion (E-FWI) and Reverse Time Migration (RTM) imaging  

technologies, the Laconia Phase III survey is designed to deliver best-in-class  

seismic data to support both exploration and development activities.  

  

Laconia Phase III OBN acquisition started in May this year and will continue  

through Q3 2025 with delivery of initial products scheduled for Q1 2026.  The  

project is supported by industry funding.  

  

"TGS 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.  

Through cooperation with Viridien and the combination of our leading edge OBN  

acquisition and imaging technologies, we are confident this project will provide  

tremendous value to our customers."  

  

"The success of our Laconia OBN program is a compelling example of the value  

that technological innovation brings to offshore exploration," said Sophie  

Zurquiyah, CEO of Viridien. "By teaming up with TGS 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. The early-out results from  

Laconia Phase I have already attracted considerable industry attention,  

highlighting the effectiveness of our advanced imaging capabilities."
