Learning Stratigraphically Consistent Relative Geologic Time from 3D Seismic Data via Sinusoidal Mapping

Hui Gao, Xinming Wu, Yimin Dou, Zhengfa Bi

Mapping relative geologic time to a sinusoidal space lets deep learning produce more accurate and topologically consistent stratigraphic fields from 3D seismic data.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

RGT-Est achieves state-of-the-art performance among AI-based methods without horizon constraints, and attains substantially higher horizon-correlation accuracy and global topological consistency once sparse priors are incorporated.

C2weakest assumption

That transforming RGT into a sinusoidal space explicitly encodes periodic stratigraphic semantics and alleviates over-smoothing of fine horizons without introducing new artifacts or losing topological information in complex real-world structures.

C3one line summary

RGT-Est transforms RGT estimation into a sinusoidal space with joint losses to capture fine horizons and global stratigraphic order from seismic data, outperforming prior AI methods especially with sparse horizon priors.
