XWI on Vintage Land Data

→

Acquired across multiple surveys in the 1990s, the data lacks low frequencies, long offsets, and is sparse. Further complications arise due to the topography and near surface effects.
The input data for FWI was minimally preprocessed - denoising and wavelet consistency. S-Cube applied its proprietary Adaptive Waveform Inversion (AWI) and Reflection Waveform Inversion (RWI) workflow to refine the model to 20Hz.

Elastic XWI in Deep-water Application

→

Starting from no assumed salt, Constrained Adaptive Waveform Inversion (cAWI) approximates the salt location. Subsequent 7Hz AWI-RWI refines the salt geometry and pre-salt trend. Finally, 20Hz elastic AWI-RWI-FWI sharpens the details.
45Hz RTM provides high-resolutution imaging.

Mahanadi Basin, India

Overcoming Deep-Water Velocity Model Challenges

→

The Mahanadi Basin, a polycyclic, peri-cratonic passive margin off India's east coast, presents one of the toughest challenges in marine seismic imaging. Shaped by NE–SW horst–graben systems, complex fault networks, and abrupt velocity contrasts, it hosts Mio–Pliocene Channel-Levee Complexes (CLCs), proven gas-bearing reservoirs and high-value exploration targets. S-Cube's staged FWI workflow not only sharpened CLC imaging, but also distinguished lithologies, clarified reservoir geometry, and removed structural sag artifacts, enabling more confident and accurate exploration.
