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."
