Abstract

See full text

A well completion system for a side valve tree that has a precision cut low profile helix that can be used in completing a wellbore where the bore is substantially curved is provided. The well completion system has a typical spool body assembly having an inside surface defining a vertical bore extending therethrough and having at least a lateral production fluid outlet port. The spool body assembly has a helix is positioned at the lower end. The helix has a tubular member having a generally cylindrical outer surface defining an outer diameter and a generally cylindrical inner surface defining an inner diameter, an upper end and a lower end. The tubular member has an organ pipe-shaped cut in the upper end so that the upper end is generally elliptically shaped to form a pair of arcuate ramps which meet at an apex at the upper end and at a longitudinally extending slot near the lower end and a means for attaching the helix to the spool body assembly. An orientation key on the tubing hanger is precision machined to match the profile of the helix.
