Abstract
A well completion system for producing fluids from a wellbore provided in a subterranean reservoir is provided. The well completion system includes tubing segments connectable to one another along the wellbore. The tubing segments include injection segments provided along the wellbore in spaced-apart relation to each other, each injection segment has an injection valve toollessly operable between a closed configuration preventing fluid flow into the reservoir, and an open configuration allowing fluid flow into the reservoir. The tubing segments also include production segments provided along the wellbore in a staggered relation with respect to the injection segments and configured to allow fluids received from the reservoir to be produced from the reservoir. The tubing segments each are configured to include injection fluid passages and production fluid passages isolated from one another along the wellbore to enable synchronously injecting and producing fluids to and from the reservoir at respective fractured locations.
