In a method and apparatus for transferring material in a wellbore in an earth formation, a pipe is inserted into the wellbore. A conduit is inserted alongside the pipe into the wellbore. The conduit is fixed to the pipe and has a first section with a perforated wall located adjacent a non-production interval of the formation, and has a second section with an unperforated wall located adjacent a production interval of the formation. The material is injected into the conduit and out the perforated wall of the first section of the conduit.
