Blueback ODiSI

One dimensional stochastic inversion.

A clearer and more robust approach to seismic inversion.

A new seismic inversion technique for geophysicists.

For geoscientists who need reliable reservoir insights, Blueback ODiSI provides a practical seismic inversion method that uses only the strongest prior information. This helps teams estimate facies and reservoir properties with confidence and understand the associated uncertainties.

What Blueback ODiSI offers

Blueback ODiSI is a facies‑based seismic inversion technique developed by BP and further adapted for the Petrel* E&P software platform in collaboration with Cegal. The method focuses on robustness. It uses a streamlined set of inputs to jointly estimate facies and rock properties while quantifying uncertainty in the results.

Independent trace inversion with lateral consistency

The algorithm is designed to work without predefined lateral constraints. Each seismic trace can be inverted independently, yet the method still achieves lateral continuity in the final model. This gives users flexibility without sacrificing geological realism.

Integrated into your Petrel workflow

Blueback ODiSI is fully integrated into Petrel* and complements Cegal’s quantitative interpretation solution, Blueback Rocks QI.

Together, these tools support day‑to‑day interpretation and reservoir characterization in a consistent environment.
