Abstract
Apparatus and methods for testing inductively coupled downhole systems are described. An example inductive coupler assembly for use in a wellbore includes an inductive coupler fixed to a completion in the wellbore, a drill pipe, a portion of which is to be located adjacent to the inductive coupler, and a sleeve surrounding the portion of the drill pipe to reduce a reluctance of a magnetic circuit including the inductive coupler.
