A downhole tool includes a sand control device, a tubular member coupled to and positioned below the sand control device, a shifting device coupled to the tubular member, and a load-monitoring sensor coupled to the tubular member and positioned between the sand control device and the shifting device.

Load-monitoring sensor proximate to a shifting device

A downhole tool includes a deactivation member, a latching member, a release member, and a biasing member. The deactivation member includes an outer protrusion. The latching member is positioned radially-outward from the deactivation member. The latching member includes an inner protrusion and an outer protrusion. The release member includes a sleeve extending axially toward the outer protrusion of the latching member. The biasing member exerts an axial force on the latching member.

Downhole shifting tool

A downhole tool includes a shifting device and a load-monitoring sensor positioned above the shifting device. A distance between the shifting device and the load-monitoring sensor is less than or equal to about 10 m.

A technique facilitates formation of a gravel pack in a wellbore. Gravel slurry is delivered downhole to a desired gravel packing zone located along an annulus surrounding a gravel packing completion. Dehydration of the gravel pack is facilitated by providing a return flow path for a carrier fluid along drainage layers of adjacent screen assemblies. The drainage layers of adjacent screen assemblies are coupled by drainage layer shunt tubes which bypass corresponding couplings between the adjacent screen assemblies. In some applications, the drainage layer shunt tubes facilitate delivery of the returning carrier fluid to a sliding sleeve assembly.

System and methodology for facilitating gravel packing operations

To operate a device for use in a well, a counter mechanism is provided that is actuatable by pressure cycles to an active position that allows actuation of the device to a target state. A position retention mechanism is coupled to the counter mechanism to maintain the counter mechanism in the active position once the counter mechanism has been incremented by the pressure cycles to the active position.

Position retention mechanism for maintaining a counter mechanism in an activated position

A technique enables failsafe control over actuators used to actuate downhole tools. The technique may utilize a well system having a tool with an adjustable member. An actuation mechanism serves as a fail-as-is mechanism and works in cooperation with the adjustable member. The actuation member is shiftable upon receiving a predetermined input; however the actuation member does not move the adjustable member upon each shift. Once the actuation member has been shifted the requisite number of times to move the adjustable member to another position, at least one subsequent shift of the actuation member is not able to cause movement of the adjustable member. The result is a fail-as-is technique for ensuring the tool is not inadvertently actuated to another operational position.

Fail as is mechanism and method

A packer includes a sealing element, a gage and a plurality of foldback rings. The rings are located between the gage and the sealing element.
