TECHNICAL DESCRIPTION

Outline

The TransGen software provides a quick and geologically-sound system for estimating and including either single or two-phase fault-rock properties in flow simulation models such as Eclipse, MoReS (Shell users) or MORE (Roxar Modular Oil Reservoir Evaluation).

The effect of faults on the modelling of fluid flow in reservoir simulation models is achieved by using transmissibility multipliers.  These are a function of the properties of the fault-rock and of the grid-blocks to which they are assigned.  

TransGen imports Eclipse format data files to define the model geometry and grid-block properties. Within TransGen, the geological factors influencing the properties of fault zones can be incorporated in a flexible, user-defined manner to construct high-resolution, geologically-correct faulted transmissibility model(s).

The software outputs transmissibility (and other) fault surface properties as Eclipse keywords for incorporation into simulation run file.

Model above is the PUNQ coarse model

TransGen has been developed through a joint venture between the Fault Analysis Group at University College Dublin (formerly of University of Liverpool) and Badley Geoscience Ltd.   Badleys and the Fault Analysis Group have been co-operating for over 10 years in the application of structural geological techniques to fault-mapping and fault-seal problems in the hydrocarbon industry.  It was one of several tools developed as part of the STAF project (Software Toolkit for Analysing Faults) partly funded by the UK Department of Trade and Industry.
