Ease of Use Features    

·         Graphical User Interface. Point and click with mouse to select options from command buttons, drop down menus, and check boxes.

·         Full on-line PDF Help. Obtain detailed description of menu items for each displayed form. Search help file for topics or keywords.

·         Spreadsheet-type data entry forms with inline data cell editing. Edit functions such as copy and paste, fill down, fill right, and undo.

·         No more keywords or syntax problems.

·         Exchange data with other standard Microsoft WindowsTM applications. Cut and paste customized well summaries to word processors for reports. Copy tabular data to spreadsheet programs for enhanced manipulation and paste back.

·         Run the simulator in the background when other time critical tasks need to be done. Monitor flood fronts and performance of wells with post processing programs such as Grid Display, WellCharts and WellReport while the run is still processing. Stack up multiple cases to run at specific times for batch processing.

·         Output to any Microsoft WindowsTM supported printer or plotter (colour or b/w).

Simulator Features
