    Abstract: A technique facilitates improving a completion architecture for a multilateral intelligent well completion (IWC). Effectively, a new and enhanced completion design and deployment approach is provided for multilateral IWCs. According to an embodiment, lower completion equipment is initially deployed downhole into a lower lateral borehole and lower section of a primary borehole. An intermediate completion may then be run downhole and into engagement with the lower completion equipment. Subsequently, an upper lateral borehole (or boreholes) may be drilled and completed. After drilling and completing the one or more upper lateral boreholes, an upper completion is deployed downhole and coupled with the intermediate completion in a manner which enables signal communication with downhole sections of the well.

    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.

    Abstract translation: 由多个相对的定向单向密封件组成的密封组件。 该组件包括用于每个单向密封件的专用测试端口。 因此，第一测试端口可以被引导到第一密封件，使得如果第一密封件泄漏，则第二密封件被构造成折叠并允许与其连接的第二测试端口以检测第一密封件的泄漏。 同样地，第一测试端口可用于检测第二密封件中的任何泄漏，当第一密封件由于泄漏而折叠时，可检测到该泄漏。 这种独特类型的结构允许可靠地测试可能容易从多个方向泄漏的多重密封组件的可靠方式，例如来自管的孔或环形侧。 这使得双向可测试的密封结构有利于结合到井下完井硬件中，例如固定在载体装置上的测试计量器的位置。

    Abstract: A technique facilitates verification of the integrity of a lower completion prior to deployment of a corresponding upper completion. A lower completion is initially deployed downhole into a wellbore and comprises a plurality of functional components, such as a sensor, a communication system, a flow control system, and/or other functional components. A service tool system is removably deployed into the wellbore and comprises a service tool with an interface which interacts with the lower completion. The interface enables verification of the integrity, e.g. functionality, of various functional components of the lower completion without the use of an additional communication line, e.g. power cable, routed separately to the lower completion.
