WebAfter training different MLs on the designed lithofluid facies logs, we chose a bagged-tree algorithm to predict these logs for the target wells due to its superior performance. This … WebThe LithoFluid Probability process uses Bayesian prediction to calculate probabilities and perform classification using statistical rock physics models. Two volumes are required with content matching the data in the statistical model (e.g. Acoustic Impedance and Vp/Vs, mu*Rho and lambda*Rho).

WebCrossplot between P-impedance and VP-VS ratio for data from Atlantis well, and for the interval between the Stø and Kobbe markers, with a rock physics template overlaid on … WebAfter training different MLs on the designed lithofluid facies logs, we chose a bagged-tree algorithm to predict these logs for the target wells due to its superior performance. This algorithm predicted HC units in an accurate interval (above the HC-fluid contact depth), and it showed a very low false discovery rate.
Webporosities, the sands will still be suitable for lithofluid discrimination due to the good thickness of the sands, although the sensitivity is reduced (Fig. 3-5). Figure 3 Modeling results (Negative 10 p.u scenario. Even at reduced porosity, the sands will be relatively suitable for lithofluid discrimination due to the good thickness of the sands. WebABSTRACT We have developed a technique to design and optimize reservoir lithofluid facies based on probabilistic rock-physics templates. Subjectivity is promoted to design possible facies scenarios with different pore-fluid conditions, and quantitative simulations and evaluations are conducted in facies model selection. This method aims to provide …
