23. The method of claim 1 , further comprising: determining a second objective function, wherein the second objective function represents a specified objective of reservoir operations; and using the optimizer and the parameterized model to determine operation of the reservoir that satisfies the second objective function.
28. The method of claim 23 , wherein said using the optimizer and the parameterized model to determine operation of the reservoir that satisfies the second objective function subject to one or more operational constraints comprises: determining one or more completion depths for one or more wells.
