    Abstract: A completion string includes at least one isolation packer positioned between well zones of a plurality of well zones, and a sand control assembly and a circulating assembly each disposed uphole of a washdown shoe in the bottom-most well zone. A top well zone includes a return valve assembly, a production packer, and a second circulating assembly and a second sand control assembly downhole of the production packer. The completion string also includes an outer string spanning from the bottom-most well zone to the top well zone, and an inner production string concentrically arranged within the outer string, creating an inner-annulus between the outer string and inner production string. The inner-annulus is continuous from the washdown shoe to the return valve assembly, and the inner production string includes a production valve disposed between the sand control assembly and the circulating assembly in each of the bottom-most and top well zones.

    Abstract: A downhole tool includes a deactivation member, a latching member, a release member, and a biasing member. The deactivation member includes an outer protrusion. The latching member is positioned radially-outward from the deactivation member. The latching member includes an inner protrusion and an outer protrusion. The release member includes a sleeve extending axially toward the outer protrusion of the latching member. The biasing member exerts an axial force on the latching member.

    Abstract: A technique facilitates formation of a gravel pack in a wellbore. Gravel slurry is delivered downhole to a desired gravel packing zone located along an annulus surrounding a gravel packing completion. Dehydration of the gravel pack is facilitated by providing a return flow path for a carrier fluid along drainage layers of adjacent screen assemblies. The drainage layers of adjacent screen assemblies are coupled by drainage layer shunt tubes which bypass corresponding couplings between the adjacent screen assemblies. In some applications, the drainage layer shunt tubes facilitate delivery of the returning carrier fluid to a sliding sleeve assembly.

    Abstract: A downhole tool includes a base pipe having an opening formed radially-therethrough. The downhole tool also includes a valve positioned at least partially within the opening. The valve includes a dissolvable insert and an impediment. The dissolvable insert prevents the impediment from contacting a seat of the valve such that the valve permits fluid flow in both axial directions through the valve. After the dissolvable insert dissolves, the impediment contacts the seat such that the valve permits fluid flow in one axial direction through the valve but prevents fluid flow in the opposing axial direction through the valve.
