  1. PTTCSimulation Users Group An Overview of the Exodus Simulation Computer Program October 23, 2003 Presented by Walt King, PE Walt King, Petroleum Engineer

  2. Exodus SimulatorPresentation • General Overview. • A little more detail. • Data Input Helps. • Debug Helps. • Lets run some cases and take a look. Walt King, Petroleum Engineer

  3. EXODUSReservoir Simulator for Microsoft Windows • Designed for use with Windows 98, 2000, NT, XP. • Graphical User Interface. • Full on line help. • Menu or Spreadsheet type data entry. • Easy exchange between other Microsoft Windows Applications. • Computer Assisted History Matching. • 2D and 3D Visualization PLUS Animation • Very User Friendly • WWW.PETROSTUDIES.COM Walt King, Petroleum Engineer

  4. General Description • Fully Implicit, 3 phase, 3D, with 2 or more components • Black oil (3 component) or Dry Gas (2 component), or • Will Handle as many as 9 Miscible components – K value formulations. • Field or Metric Units. • Calendar Dates or Day numbers. • Full Field or Automatic Generation of Pattern, or radial. Walt King, Petroleum Engineer

  5. General Description Continued • Polymer or Alkali Surfactant Polymer flooding. • Pressure Transient Analysis. • Hydraulic Fracturing. (Template or Local Grid Refinement) • Coal Bed Methane (with and w\o CO2 and N2 injection) • Horizontal wells • Water, Gas or CO2 Flooding • Dual Porosity/Dual Permeability Walt King, Petroleum Engineer

  6. A Little More Detail • Historical Data entry from Excel Spreadsheet or Commercial Source. • Cell data input: • Manual (direct entry, add, subtract,multiply, do “if”) • Digitized map (s) • Formula • Exodus Interpolation • Excel Spreadsheet • Import from previously defined saved Reservoir data file. • Computer Assisted History Matching • Fluid Data Input: (up to 10 data sets) • Manual for PVT data • Import from previously saved PVT data file • Excel Spreadsheet • Built-in “Standing’s Correlation” Walt King, Petroleum Engineer

  7. Even More Detail • Relative Permeability (Saturation Functions) • Manual Input from Special Core Analysis. • Excel Spreadsheet. • Built in “Honarpour & Larson-Hirasaki Correlations”. • Computer assisted History matching. • Rescale Function. • Well Locations • Manually • From Excel Spreadsheet. • Mouse Click • X, Y, & Z Direction Walt King, Petroleum Engineer

  8. More .. • Time Dependent & Pressure Dependent Parameters. • Program Execution: • Run in foreground or background. • Setup up to 10 files to run sequentially. • Set up to compute now or later. • Watch computation status on Status Menu. • Watch production plot as computation progresses. • Output Plots: • Easy to setup plots yourself. • Use Exodus predefined plots. • Duplicate well plots using Template. • Easy to Change output file being plotted. Walt King, Petroleum Engineer

  9. Still More… • Tabular Well Reports • Individual well by date. • Group of wells on a given date. • Wells by parameter by date. • Summary of field or pre defined group of wells. • Individualize your report by column parameter. • Grid Display Utility • 2 D or 3 D display. • Animated display. • Data display. • Tabulation of Oil, Gas, Water in place by time. Walt King, Petroleum Engineer

  10. Where to Get Help Running the Program • PetroStudies - Exodus User Course (Beginner & Intermediate). • Computer user instruction manual-160 pages-Print or watch on screen. • Movies Illustrating how to set-up and run various problems. • Push F1 key for detailed help. • Required items are CAPITALIZED or noted “R” (“O”=optional) • Message Box makes suggestions when arrow touches cell. • If data is outside of “envelope” or data does not fit computation conditions, screen message will “ping” and make suggestions. Walt King, Petroleum Engineer

  11. Getting Help Debugging your file • Exodus makes a final check when you save Data file. • Simulator Status File has Messages detailing run history and problems that occurred during the computation run. • Cell error map shows which cells had problems computing and whether it was with oil, gas, or water phase. • You can watch run in progress on status screen and see where simulator has difficulty converging. Walt King, Petroleum Engineer

  12. Now… Lets Try Some Cases • “Exodus Ignition” • “Pre-Processor” - Input Data • Primary Gas Production • Waterflooding with a horizontal well • Polymer Flood • CO2 Flood • CBM Forecast • Frac Model • Local Grid Refinement Walt King, Petroleum Engineer
