Numbat3D
A program to generate 3D facies models of petroleum reservoirs.
Summary
 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. 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).

Predict2D
A program to generate 2D vertical sections of sedimentary successions.
Summary
 An earlier version of the parser which generates 2D vertical sections through sedimentary successions. The sections can be conditioned to 1D data (such as well data).
