You're at the boundary of my knowledge set (hard to believe isn't it).
I've always thought these things are delivered via a coiled tubing set up - so easy to pull it up and set it back down again.
Besides, wells are always being maintained. As the link from "Nabors" says - usually an engineered solution for paraffin/wax problems - which the Cline is.
So my guess is they would pull it up, set whatever packers to stop the flow from below, frac the upper levels and then set it back down. But only a guess.
