Abstract
A downhole fluid flow control system and method includes a fluid control module having a main fluid pathway, a valve element and a pressure sensing module. The valve element has open and closed positions relative to the main fluid pathway to allow and prevent fluid flow therethrough. The pressure sensing module includes a secondary fluid pathway in parallel with the main fluid pathway having an upstream pressure sensing location and a downstream pressure sensing location. In operation, the valve element moves between open and closed positions responsive to a pressure difference between pressure signals from the upstream and downstream pressure sensing locations. The pressure difference is dependent upon the viscosity of a fluid flowing through the secondary fluid pathway such that the viscosity is operable to control fluid flow through the main fluid pathway.
