Sinopec deploys 65,000 Sercel land nodes for
complex 3D survey in Mexico

Paris, France – August 26, 2025

Viridien has announced that its Sensing & Monitoring business line, marketed under the
Sercel brand, has sold and successfully delivered a complete land nodal acquisition system to
Sinopec, one of the world’s leading energy companies. The system, featuring 65,000 WiNG
nodes, is currently being deployed to acquire a 3D seismic survey spanning approximately
3,000 square kilometers in the Tabasco and Veracruz regions of Mexico.

The project covers a variety of challenging terrains, including plains, flooded areas, swamps,
and hills. It has already moved into the production phase, with operations running smoothly
on the ground. The WiNG system’s exceptional performance, efficiency and reliability are
playing a key role in ensuring the delivery of optimal data quality for outstanding subsurface
imaging, even in difficult field conditions.

Engineered for complex environments—including marshlands and dense vegetation—the
Sercel WiNG system combines a fully scalable architecture with advanced wireless
communication technology to deliver high-density, high-resolution seismic data under the
toughest conditions. Thanks to its proven Pathfinder transmission management technology,
field crews can monitor the entire acquisition spread in real time, enabling thorough and
efficient quality control throughout the operation.

Jerome Denigot, Head of Sensing & Monitoring, Viridien, said, “This delivery marks an
important milestone in our long-standing partnership with Sinopec. We are especially pleased
that survey production is underway and progressing as planned. It highlights the strength of
our technology and the quality of support our teams provide on-site. This significant project
further solidifies Sercel’s presence in Latin America and confirms the growing worldwide
adoption of nodal acquisition systems for large, high-end seismic exploration surveys. This
will enable us to demonstrate the full potential of our Sercel nodal range, including our latest
Accel drop node.”
