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
v Pre-Tax Economics - compare the present values of different cases given
price and cost data.

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 Master
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.
