SPG India 2025: Rock to Cloud - A Case Study from Deep-Water Block Mahanadi Basin, India
October 27, 2025
S-Cube and ONGC showcase their latest results from deepwater Mahanadi Basin. A multi-stage Full-Waveform Inversion (FWI) strategy, using S-Cube's XWI, was able to successfully correct structural sags below localized velocity anomalies and define Gas-Charged Mio-Pliocene Channel Levee Complexes from scratch.

Onshore FWI in India: S-Cube & ONGC Recognised at SEG Bengaluru for Bengal Basin Results
Vikas Vats and Christos Mavropoulos of S-Cube and Saheb Ghosh of ONGC-GEOPIC received SEG certificates of appreciation for their talks on full waveform inversion in India, and Nikhil Shah of S-Cube was recognised for his keynote. The talks showed the first FWI results on real Indian field data, now guiding exploration and development decisions. The joint work applied Time-Space-Lag FWI (TSL-FWI™) to a legacy onshore dynamite survey in the Bengal Basin, correcting velocity distortions below 6 km, 4x deeper than diving waves reach. The case study is published as an SEG 2026 paper.

Transforming Energy Exploration: Technology, Sustainability, and Innovation Symposium
S-Cube presents four technical talks in Bengaluru on Friday 25 September, including a joint session with ONGC-GEOPIC on land seismic FWI in the Bengal Basin — among the first FWI applications in India with ONGC, spanning both offshore and onshore settings. The talks cover next-generation FWI for land and marine applications and building confidence away from well control with Time-Space-Lag FWI.

IMAGE '26: S-Cube presents Time Space Lag FWI for Land and Marine Settings
S-Cube has had two abstracts accepted for oral presentations at IMAGE 2026 in Houston (August 17-20). The talks cover onshore subsalt updates via FWI-Derived-Reflectivity-Driven Reflection Waveform Inversion, and breaking through complex salt by harnessing Time-Space-Lag Adaptive Waveform Inversion together with Reflection Waveform Inversion.
