BLUEBACK ODISI

ONE DIMENSIONAL STOCHASTIC INVERSION

Blueback ODiSI is a One Dimensional Stochastic Inversion method that produces high quality reservoir property estimates with associated uncertainties, to predict net fraction, porosity and lithofacies distribution in geological plays. It is a unique seismic inversion method that specifically includes only the most robust prior information in order to apply additional constraints to the solution.

Blueback ODiSI does not require any prior lateral constraints: the algorithm converges so that each trace can be inverted independently of its neighbors yet laterally continuity is still achieved.

The technology was originally developed by BP (Connolly & Hughes, 2013, 2014, 2016) while a Petrel* version has been developed jointly by Cegal and BP. The solution is robust yet logical and comes fully integrated into Petrel, complementing Cegal’s Quantitative Interpretation solution Blueback Rocks QI.
