Abstract
A system for producing hydrocarbons from a subterranean well including a wellbore extending from a surface into a subterranean formation, the system including a wellhead disposed at the surface. In addition, the system includes a production tree coupled to the wellhead. Further, the system includes a casing coupled to the wellhead and extending into the wellbore. Still further, the system includes a first plurality of production tubing strings extending into the casing from the wellhead to a first production zone. Each of the first plurality of production tubing strings is configured to provide a fluid flow path for gases from the first production zone. The production tree is configured to selectively and independently control fluid flow through each of the first plurality of production tubing strings.
