TransGen and TT-TransGen |
| Brochure |
The physical properties of fault zones are the most influential factor in the prediction of cumulative oil production. Incorporating fault properties into reservoir models is a major challenge. Current methods are time-consuming and can produce non-unique, subjective solutions. The common practice of using a single value for the transmissibility multiplier for an entire fault is geologically unrealistic and can result in unreliable flow prediction.
TransGen is leading-edge technology, developed in collaboration with the Fault Analysis Group, University of Dublin, for deriving geologically robust properties for faults in reservoir simulation models. Advanced options include fully flexible fault-rock properties, calculation of two-phase fault-rock properties and implicit inclusion of sub-resolution fault-zone structures.
With the release of TrapTester 6 in 2009, much of the TransGen functionality was ported into TrapTester as the "TT-TransGen" module. Both the stand-alone TransGen application and the TT-TransGen module are available depending upon your requirements.

Key Features: |
|||
3D Visualization |
Display geocellular model and cell properties to reveal geometric and geological deficiencies that may be corrected in the reservoir model prior to the simulation |
||
Direct data link to ECLIPSE™ |
TransGen extracts geological data from ECLIPSE™ models, computes fault properties, and exports the results back to ECLIPSE™. |
||
User-defined relationships |
Intelligent application of geologically derived empirical relationships and property calculations to predict fault properties. |
||
Two phase flow modeling |
TransGen incorporates capillary pressure and relative permeability data, together with across
fault flow rates, to derive upscaled pseudo relative permeability functions for cell faces at faults.
|
||
Incorporating sub-resolution structure |
User-defined input parameters to implicitly incorporate the effects of drag and relay zones into the calculation of transmissibility multipliers. Sub-seismic relay zones can be viewed as 'mini models' that show the extra reservoir connections generated at relays. |
||
Key Benefits: |
|||
Improved history match |
TransGen delivers geologically-conditioned transmissibility data that are used to produce history matches as good or better than those obtained from months of conventional history matching saving engineer-time and money |
||
Lower simulation risk |
Determine fault properties from stochastic sedimentological realizations in sensitivity studies |
