WinCast allows the user to directly calculate the Inflow Performance IPR curve for the iteration time step by using input data on reservoir properties provided by the user, the calculated reservoir pressure (from gas storage reservoir P/Z or as input by the user if no storage reservoir is defined), and the flowing well pressure (or rate). Well productivity can be individually controlled by system constraints (including tubing strings), surface back-pressure (chokes) or by user-defined limits on rates. In addition, WinCast has the ability to input well or field deliverability (rate vs. cumulative production) equations.

This module can also be used to perform multi-scenario studies for a given pipeline system. For example, an engineer or operator may wish to run a series of capacity analyses for a given pipeline network using many different pressures, set points, and loading configurations. The data for all the various scenarios can be directly input or uploaded into WinCast and all the multiple runs can be performed and the results displayed using one single model rather than one model per scenario.

WinCast Applications:

• Provides insight with which to optimize and ensure efficient operation of existing systems;
• Predicts field and well rates over days, weeks, months or years;
• Performs deliverability calculations;
• Allows for efficient planning of field and well production, injections and withdrawals;
• Provides sensitivity analysis;
• Provides insight for new system design (pipelines, compressors, wells, etc.) and required timing;
• Allows for well controls to safeguard reservoirs and equipment
• Determines the production life and depletion profile of fields;
• Multiple Scenarios Analysis using one single model.
