Abstract
Bypass devices are disclosed for providing alternative flow paths within an annulus formed around a production string of a subterranean wellbore. In some embodiments, the bypass devices include inlet flow paths and outlet flow paths in fluid communication with the annulus so that fluids may flow through the inlet and outlet flow paths to bypass a blockage in the annulus. The bypass devices are also configured to avoid internal blockages within the internal flow paths defined by the inlet flow paths and outlet flow paths.
