LITHOSI

LithoSI quantifies uncertainty in seismic lithology and fluid prediction. Using multiple elastic parameters from the inversion of seismic data, LithoSI performs a supervised Bayesian classification to deliver probability cubes of predicted lithology and/or fluid properties. The integrated inversion and classification workflow provides superior definition of lithology classes and allows more accurate assessment of lithology probabilities.

Quantify Uncertainty in Seismic Lithology and Fluid Prediction

LithoSI is able to design complex multi-variate probability distribution functions to ensure that lithologies are properly classified and their probabilities accurately defined. The resulting litho-probability cubes enable the reservoir engineer to make a full assessment of the uncertainty in the range of net-pay scenarios and reduce production risks.
