Abstract: A seal assembly made up of multiple opposite oriented unidirectional seals. The assembly includes a dedicated test port for each of the unidirectional seals. Thus, a first test port may be directed at the first seal such that if the first seal leaks, the second seal is configured to collapse and allow a second test port coupled thereto to detect the leak of the first seal. By the same token, the first test port may be used to detect any leak in the second seal which is detectable as the first seal collapses as a result of the leak. This unique type of architecture allows for a reliable manner of testing a multiple seal assembly that may be prone to leaks from multiple directions, for example from either a bore or an annular side of a tubular. This renders the bidirectionally testable seal configuration beneficial for incorporation into downhole completions hardware such at the location of a test gauge secured to a carrier device.
