Patent attributes
A downhole completion system includes an intermediate casing, an outer production casing arranged at least partly within the intermediate casing, a main barrier to seal between the intermediate casing and the outer production casing, and an inner production casing arranged at least partly within the outer production casing. The outer production casing has a first outer inductive coupling arranged below the main barrier, and a first inner inductive coupling is arranged on an outer face of the inner production casing for wireless transfer of communication signals and/or power therebetween. The first inner inductive coupling is connected to the top of the borehole via a first electrical conductor, and a second outer inductive coupling is arranged on an outer face of the outer production casing and connected with the first outer inductive coupling via a second electrical conductor.
