An autonomous flow control device includes a valve plate having a surface and a valve element at least partially formed on the surface. The valve element has an inlet and an outlet with a fluid flow path extending therebetween. The fluid flow path included a viscosity dominant flow path configured to provide a first flow resistance and an inertia dominant flow path configured to provide a second flow resistance that is greater than the first flow resistance such that when the viscosity of the fluid flowing therethrough is greater than a first predetermined level, the fluid follows the viscosity dominant flow path with the first flow resistance and when the viscosity of the fluid flowing therethrough is less than a second predetermined level, the fluid follows the inertia dominant flow path with the second flow resistance, thereby regulating the production rate of the fluid responsive to changes in fluid viscosity.
