STEP 1: Enter the Rate Constraint
To limit production at a well, simply type a specific number into the Contract Rate (MMscf/d) column as shown below. In some modules, you may be able to constrain by either water, gas, or oil depending if it is single or multiphase flow.
STEP 2: View Results on Forecast Tab
The production forecast than shows the well deliverability with a maximum rate of 20 MMscf/d. When the reservoir energy can no longer support this rate, the well begins to decline again. If there was insufficient energy initially, the well would follow the Flowing BH pressure constraint.
