    Abstract: A completions fluid loss control system for incorporation into upper completion hardware. The system allows for the avoidance of a dedicated intermediate completion installation in advance of upper completion delivery to a lower completion at a formation interface. The system includes a unique cup packer and flow regulation arrangement such that annular fluid thereabove may be isolated away from space below the system while at the same time allowing annular fluid therebelow to bypass the system. As such, the upper completion may be advanced toward the installed lower completion while maintaining well control at the noted formation interface.

    Abstract: A technique facilitates controlled injection of a chemical injection fluid at a desired downhole location. A chemical injection valve is mounted along a well tubing and is disposed externally of an internal flow passage through the well tubing. The chemical injection valve is operated via hydraulic pressure which is applied to actuate the chemical injection valve between closed flow and open flow positions. The chemical injection valve controls flow of the chemical injection fluid to at least one injection port. The at least one injection port may be positioned to inject the chemical injection fluid into the internal flow passage of the well tubing.

    Abstract: A drill stem test string may include a tubular body having an axial bore formed at least partially therethrough. An axial flow valve may be coupled to the first tubular body and allow fluid to flow axially through the first tubular body when in an open state and prevent fluid from flowing axially through the first tubular body when in a closed state. A radial flow valve may be coupled to the first tubular body and allow fluid to flow radially through the first tubular body when in an open state and prevent fluid from flowing radially through the first tubular body when in a closed state. A seal assembly may be coupled to an outer surface of the first tubular body and positioned between a lower end of the first tubular member and the first radial flow valve.

    Abstract: A completion assembly includes tubing that defines an axis that extends from a distal shoe end to a proximal uphole end where the tubing includes: a washdown shoe; a plug seat configured to receive a plug that hinders flow through the washdown shoe; a screen; a fluid loss control device that permits, in an exterior space, flow of fluid in an uphole direction and that hinders flow of fluid in a downhole direction; a circulation valve that is actuatable to permit flow of fluid from an interior space to the exterior space; a formation isolation valve that is actuatable to form a flow barrier in the interior space; a packer that is actuatable to extend radially outwardly from the tubing to form an annular flow barrier in the exterior space; and a barrier component that is actuatable to form a flow barrier in the interior space of the tubing.

    Abstract: A technique facilitates monitoring of load forces at various locations along a well string. The technique enables determination of loading based on measurement of hydraulic pressures, and the technique may be used to determine axial loading along a variety of downhole completions. A compensating piston may be disposed in a fluid chamber between a housing and a mandrel of one of the completions. The mandrel is slidably received in the housing and the fluid chamber is coupled with a sensor gauge via a pressure communication passage to facilitate accurate measurement of loading via the hydraulic pressures in the fluid chamber. The load forces may be monitored during, for example, landing of an uphole completion into a downhole completion. The sensor gauge also may be used for monitoring other pressures along the overall completion.

    Abstract: A technique combines a wireless coupler system with casing to communicate signals from and/or to a device external to the casing. The wireless coupler system may comprise an inductive coupler system formed with a female inductive coupler disposed along an exterior of the well casing and a male inductive coupler mounted along tubing disposed within the well casing. The female inductive coupler is operatively coupled with the sensor and the male inductive coupler is operatively coupled with a communication line routed along the tubing. The inductive coupler system is constructed to facilitate alignment of the male inductive coupler with the female inductive coupler as the tubing is moved along an interior of the well casing. Additionally, the inductive coupler system may be constructed with a bypass channel to facilitate the flow of fluid and routing of communication lines through the inductive coupler system.
