In a top well zone, the outer completion string includes a latch profile, a female inductive coupler, a gravel pack packer, and a sand control assembly and a gravel pack extension disposed downhole of the gravel pack packer. The inner service string includes, among other components, an inner concentric string that is concentrically arranged within a workstring creating an inner-annulus between the workstring and the inner concentric string. The upper completion includes a male inductive coupler that is configured to connect with the female inductive coupler of the outer completion string.
