ABSTRACT:
A method and apparatus for completing a lateral channel in a subterranean formation using a flexible hose with a waterjet that may be directed down a well casing and into a waterjet guide. The waterjet guide has a diverter assembly configured to receive and divert the flexible hose in a shortened radius. The diverter assembly includes an inlet curvature and a pivot curvature, where the pivot curvature pivots between stowed and deployed configurations in response to forces provided through a mandrel assembly communicably coupled thereto.
