... limited by poor correlation between reservoir properties from wells and seismic attributes. Flow simulation models use seismic data based on the assumptions made by the geological engineers. The study uses a cyclic approach to geological modeling: realizations include in-depth analysis of seismic data...

... reservoirs and on its dynamics during gas injection and production. In traditional hydrodynamic modeling, accounting for the existing dataset of a well logging control is problematic; traditional geometric interpolation algorithms either do not allow obtaining equally probable realizations of the modeled...

... this is far from the truth due to various regular noises. Replacing weights by random ones is equivalent to filtering with random kernel. These means assigning a random confidence levels to input gathers. This allows to generate many realizations of the input data for inverse problem. Also incorporation...

... in order to evaluate potential flow rates of different regions of reservoir. Also flow connectivity should be used to rank realizations of lithology or net to gross properties in geological models in uncertainty analysis as a parameter which reflects production properties of reservoir. geologic...

Extensive reservoir characterization under uncertainty was performed and the geometrical and rock parameters were captured by generating thousands of realizations. These realizations were clustered in Multi-Dimensional Space...
