Economic comparison of cases
EXODUS Reservoir Simulator consists of the following suite of programs
v Digitize Maps - contour maps may be traced and converted to digital form
v Historical Data Input - enter production and pressure history data
v PreProcessor – Create/Modify/Save a complete data set for the simulator
v Execute Exodus – Starts Simulation Runs for specified data sets
v Monitor Run Status – Shows progress of selected runs
v WellCharts Extract – create multiple 2D/3D charts of well(s)’s simulated and historical data
v Well Report Utility – spreadsheet reports of well(s)’s simulated results
v 2D/3D Grid Display Utility – multiple 2D (xy,xz,yz planes) and 3D maps of grid cell parameters with time.
v Network Report Utility - reports of rates and pressures at Surface Nodes and Segments at selected times
REVELATIONS - Assisted History Matching
Helps the user find the “best” match of historical wells’ production, and pressure.
Varies grid cell values of selected grid parameters for selected regions of the reservoir in search of the “best” match.
Grid parameters can be net pay, depth, porosity, directional permeabilities, initial pressure and saturations, fluid contact depths.
Initial values, minimum and maximum values for grid parameters can be set and the “best” match searched for within these bounds.
Revelations Master will launch a regression cycle of many try cases in the domain specified by the grid parameters value boundaries.
On a shared network folder, the many try cases can be simultaneously run by Revelations Run Network installed on several computers on the network. With enough Revelations Network licenses, all the try cases can be run in the time it takes to run one case.
Revelations Master will monitor and get the “best” try case. From this case, additional try cases will be launched and the regression cycles continued until no improvement is obtained.
Revelations can also run a large number of try cases with user specified values, or probe a range of regression parameters with random values to find possible local best cases.
Historical observed values to match are entered on a well basis and consist of rates, cumulatives, and pressures. Weighting Factors can be applied to values.
Revelations Report shows the error in matching each historical value. Tables and graphs of historical and calculated values, incremental and cumulative match errors are provided.
The well match errors may also be shown as bubble maps on time varying grid maps such as pressure and saturations.
Work flow demonstrated in tutorial movies.
Revelations Run Network
Execution Module. When installed on multiple computers on the network, will run simultaneously on each computer several try cases submitted to a common shared folder.
This must be purchased for each computer.

3D Well Charts
Template to build Multiple Vertical Fractures for long Horizontal Well
· Automatically creates Local Grid Refinements along Fracture path
· Very small central LGR planes to represent fractures
· Calculates each fracture’s dimension using fracture tonnage
· Enhanced Fracture permeability at specified times.
· Perpendicular or Deviated Vertical Fractures
· Template automatically removes, modifies, or rebuilds fracs
· Exodus is competitively priced based on the number of active grid cells. Purchase only the version that will fit your reservoir problems, and upgrade for the difference in price when necessary.
· Network versions available with 3+ licenses
· Single node locked license lease at low prices.
