Method of Providing a Flow Control Device That Substantially Reduces Fluid Flow Between a Formation and a Wellbore When a Selected Property of the Fluid is in a Selected Range

A method of providing a flow control device for controlling flow of fluid between a formation and a wellbore, comprising:

• defining a flow rate of the fluid through the flow control device;
• defining a desired relationship between a performance parameter of the flow control device that exhibits a substantial change when a selected property of the fluid changes in a first range and remains substantially constant when the selected property is in the second range;
• determining using a computer and a simulation program the relationship between the performance parameter and the selected property over the first range and the second range for the defined flow rate for a geometry of a flow through area of a flow control device;
• comparing the determined relationship of the performance parameter with the desired relationship;
• altering the geometry to a new geometry when the difference between the desired performance and the determined performance is outside a desired range;
• determining using the computer and the simulation program the relationship between the performance parameter and the selected property over the first range and the second range for the defined flow rate for the new geometry of the flow through area of the flow control device;
• and
• repeating the process of altering the geometry and determining the performance until the difference between the desired performance and the determined performance for a geometry is acceptable;
• and
• storing the geometry of the flow through device on a suitable storage medium for which the difference between the determined performance and the desired performance is acceptable.
