A method for removing filter cake from a subterranean wellbore includes running a completion string into the wellbore on production tubing, the completion string including one or more screen assemblies coupled therein, conveying a running tool through the production tubing to a shifting tool arranged within the completion string, opening a circulation port of the shifting tool with the running tool, flowing a spotting fluid through the running tool and the shifting tool and discharging the spotting fluid from the completion string into an annulus defined between the completion string and the wellbore, interacting the spotting fluid with the filter cake to remove the filter cake from a wall of the wellbore, and circulating the spotting fluid from the annulus and into the production tubing through the circulation port.
