Numbat3D “3D facies models of petroleum reservoirs”

The program encodes a method for generating facies models based on descriptions of outcrops of sedimentary successions or modern analogs of sedimentary systems. The method uses syntactic pattern recognition to encode facies analogs as grammars and a parser to generate stochastic facies models using the information from the grammar.

Channel

The aim of the program is to improve the reconstruction of complexely shaped sand bodies in petroleum reservoirs, particularly those from channelised environments. The facies models are generated as thin 3D layers which can be stacked to form a 3D volume. The parser is a predictive (generative) parser. It is able to condition the facies models to sparse hard data (such as the results of interpretation of poor quality seismic data).
