Ontology-based Warehouse Time-Depth Data Modelling Framework for Improved Seismic Interpretation in Onshore Producing Basins

Time-to-depth conversion has been one of the objectives of<br>seismic interpretation. There is no straightforward procedure<br>that derives a depth section from a seismic section. This is due<br>to the fact that seismic reflection times depend upon the<br>positions and shapes of the reflecting interfaces. The velocity<br>data patterns are often complex, affecting geological<br>interpretations. Depth conversion takes considerable amount<br>of an analyst's time and leaves concerns about its accuracy.<br>This uncertainty in depth conversion procedure significantly<br>contributes to pitfalls and ambiguities in depth conversion<br>velocities.
