Using WizGen in Flexible project mode

Having selected the Flexible project operating mode on the Title page, WizGen leads the user through the process of making a complete TransGen run file (<Project>.TGDATA) simply by clicking on the Next >> button after completing each stage, as described below.

NOTE:- It is strongly recommended that WizGen is always used to construct/edit the TGDATA run file as hand-editing can easily lead to mistakes.

When the TGDATA run file is completed to your satisfaction, click on the ViewGen icon in the Control Menu to initiate the calculations and to display the input model and the results in the ViewGen graphics window - see section on Viewing the model and calculating output for details.

To select Flexible project mode, possibly also include EITHER two-phase fault rock calculations OR fault drag & hierarchical zone effects.

To specify the layout of the input data, define the number of Columns, Rows & Layers and set appropriate units of measurement.

To define new keywords for cell or connection properties.

To choose which data files are included in the current TransGen run.

To optionally set FSP units and/or alter lower cutoff limits. To run the model without performing calculations, i.e. to view the input data in ViewGen.

To define the fault seal potential variables for calculating up to 5 FSP measures for the fault rock.

To create and modify user-defined calculation modules (plugins).

NOTE:- A PERM plugin to calculate fault permeability from one or more Fault Seal Potential measures plus a THICK plugin to calculate fault-rock thickness from displacement are essential for calculating faulted Transmissibility multipliers.

To specify output options and destination files for input into Eclipse, MoReS (for Shell users) and/or More (Roxar Modular Oil Reservoir Evaluation) simulation models.

To output derived fault connection, trace properties and/or data calculated for user-defined keywords to file.

The following 2 pages can only be accessed if the TransGen installation is licensed for the sub-resolution fault-zone structure functionality (new to the TransGen 3.2 release) and if the Include fault drag and hierarchical zone effects option has been toggled "on" via the Title page in WizGen in Flexible project mode.

To allow for the inclusion of uncertainty in fault throw or of local geological drag on all faults traces in the model.

To allow the construction of heirarchical fault zones, e.g. a fault represented as a continuous discontinuity in the reservoir simulation model can be segmented at a sub-resolution scale as a hierarchy of unbreached and breached relays.

The following 3 pages can only be accessed if the TransGen installation is licensed for the Two Phase Flow module and if the Include two-phase fault rock calculations option has been toggled "on" via the Title page in WizGen in Flexible project mode.

To define the two-phase flow input parameters including the file containing relative permeability tables, the keyword defining the source of across-fault flow rates and the fluid property settings including the oil-water contact.

To view/edit the fault-rock properties equations used to calculate relative permeabilities for water and oil.

To set groupings and specify destinations for two-phase flow output files.

To view the current settings in the TGDATA run file.

To view the Session log generated by the last run made with ViewGen.

To view/edit any of the current WizGen page contents, to view the current TGDATA file and/or the Session log generated by last TransGen calculation.
