The order includes three 528 acquisition systems, representing a total of 24,000 channels, and 24,000 SG-5 geophones, with delivery scheduled before year end.
ONGC will deploy the systems on oil and gas exploration surveys across difficult-to-access terrain in India during the 2026 acquisition season. This landmark deal represents one of the largest deployments of the new-generation 528 system to date in the region.
Building on the commercial momentum of the 528 since its launch in 2024, this sale highlights industry recognition of its unmatched operational flexibility, reduced power consumption, and lightweight design. With its scalable architecture, it can also be seamlessly adapted to the diverse requirements of ONGC’s upcoming survey operations. The SG-5 geophones, known for their high-sensitivity low-frequency performance, high signal fidelity and durability, will further enhance the quality of seismic data acquired during the surveys.
Jerome Denigot, CEO of Sercel, said: “We are proud to support ONGC’s exploration projects with our advanced 528 cable-based system. This contract highlights the confidence our customers place in our technology which is robust, reliable and increases productivity, even in the most complex operational settings. With this latest success, Sercel continues to expand its footprint across key energy markets, reaffirming its position as a global leader in geophysical sensing solutions.”
