Abstract: A technique facilitates operation of a valve system a having combined valve such as a combined formation isolation valve and a circulating valve. In well operations, the valve system is deployed downhole into a wellbore on a tubing string. The formation isolation valve and the circulating valve are operable independently via inputs, e.g. hydraulic inputs provided through less than three hydraulic control lines. The formation isolation valve and the circulating valve may be coupled by a mechanical linkage, which enables operation of the two valves via the hydraulic control lines. In some embodiments, the formation isolation valve and the circulating valve may be operated via an integrated shifting tool.

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 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: 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: An actuator assembly for effective interventionless activation of a valve in wells of multilateral architecture. The assembly may be pressure actuated from an oilfield surface even in certain circumstances where another valve in another leg of the well has been opened in a manner compromising pressure control of the well. Due to the multi-stage nature of the actuator, pressure based activation remains viable as a result of supplemental and/or fail-safe modes of actuation, for example, where such pressure control becomes compromised.

Abstract: A well completion system in accordance with one or more embodiments includes a shallow set barrier installed in an upper completion section of a well, a deep set barrier installed in a lower section of the well, a first sensor disposed to gauge a pressure in a first area between the deep set barrier and the shallow set barrier and a communication device to communicate the gauged pressure. The lower section may be located below a production completion when it is installed in the upper completion section.

Abstract: A technique facilitates actuation of a downhole tool, such as a valve, in a simple, rapid, and cost-effective manner. The technique comprises installing the downhole tool with a trip saver. The trip saver can be actuated by increasing a tubing pressure or other suitable pressure source beyond a threshold level. Once the trip saver is actuated, a fluid under suitable pressure is provided to a downhole tool through a passageway opened via the trip saver. This enables actuation of the downhole tool to a desired state.

Abstract: An integrated power distribution system utilizes a subsea power distribution hub that receives high voltage electricity through an umbilical from a host surface facility. The subsea power distribution hub steps down the high voltage electricity and distributes the appropriate electrical power supply to multiple components of a subsea production system (e.g., in-well pumps, subsea booster pumps, subsea processing units, subsea valves, and subsea sensors) via jumpers. The integrated subsea power distribution system can be utilize to supply electrical power to all of the required process components of the subsea production system from the in-well completion to the surface host facility.

Abstract: A control and instrumentation system utilizes a subsea data hub to establish closed loop of between subsea production system components and a surface located controller. The control and instrumentation system can be utilize to operational control all of the required process components of the subsea production system from the surface located controller.

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.

The lower section may be located below a production completion when it is installed in the upper completion section.
