Abstract: A method includes in a single trip running a completion system having an internal bore into a wellbore that penetrates a formation zone, the completion system having an upper completion connected to a lower completion, setting an isolation packer forming a barrier above the formation zone, displacing the annulus fluid above the set isolation packer and then setting an upper packer thereby providing a completion barrier above the set isolation packer. The annulus fluid may be displaced prior to setting an upper completion packer.

Abstract: A technique facilitates controlling fluid flows, such as fluid flows in a downhole well zone or zones. A flow control valve is employed to control a fluid flow and is operationally linked with an injection valve. Actuation of the flow control valve is used to automatically actuate the injection valve between corresponding positions allowing or blocking fluid injection. Closing or opening of the flow control valve thus results in a desired corresponding action of the injection valve, such as blocking flow or allowing flow through the injection valve.

Abstract: A completions assembly that includes an extendable and retractable shifting tool at a lower end of an upper completion. Outfitted with this type of tool, the upper completion may be sealably landed out at an installed lower completion without prematurely opening an isolation valve that ensures well control thereat. Rather, the full completions assembly may be finished out and the valve later opened by extending of the shifting tool from the upper completion toward the isolation valve at the lower completion. Once more, this type of well control is achieved through use of hydraulic lines that are dedicated to the upper completion even though the isolation valve is located therebelow. As a result, the extended use of hydraulic couplings and other complex or wear-prone well control architecture may be largely avoided.

Abstract: A technique facilitates performance of a work over on a completion used in a wellbore. The completion comprises an upper completion coupled with a lower completion by a mandrel and a latch. When a work over is to be performed, the upper completion is separated by moving a cutter device down along the mandrel and operating the cutting device to sever the mandrel. Once the mandrel has been severed, the latch may be activated to release the upper completion for removal.

Abstract: A completion system for use in a well includes a first completion section and a second section. The first completion section has a sand control assembly to prevent passage of particulates, a first inductive coupler portion, and a sensor positioned proximate to the sand control assembly that is electrically coupled to the first inductive coupler portion. The second section is deployable after installation of the first completion section. It includes a second inductive coupler portion to communicate with the first inductive coupler portion, to enable communication between the first completion section's sensor and another component coupled to the second section.

Abstract: Systems and methods for completing a wellbore. The system may include a first outer tubular member having an inflow control device configured to allow fluid to pass radially through the first outer tubular member. A second outer tubular member may be coupled to the first outer tubular member via an axial coupling. The second outer tubular member may have an inflow control device configured to allow fluid to pass radially through the second outer tubular member. An inner tubular defining an inner bore may be disposed at least partially within the first outer tubular member, the second outer tubular member, or a combination thereof such that an annulus is formed radially therebetween. The inner tubular member may include a flow control device configured to allow fluid to pass radially between the inner bore and the annulus.
