Abstract: Sliding sleeve assemblies including a completion body with an inner flow passageway and one or more ports enabling fluid communication between the inner flow passageway and an exterior of the completion body. A sliding sleeve is arranged within the completion body and has a sleeve mating profile defined on an inner surface, the sliding sleeve being movable between a closed position, where the one or more ports are occluded, and an open position, where the one or more ports are exposed. A plurality of wellbore darts are used and each has a body and a common dart profile that is matable with the sleeve mating profile. One or more sensors are positioned on the completion body to detect the plurality of wellbore darts traversing the inner flow passageway. An actuation sleeve is arranged within the completion body and movable to expose the sleeve mating profile.

Abstract: Disclosed is a sliding sleeve assembly that includes a sliding sleeve sub coupled to a work string extended within a wellbore, the sliding sleeve sub having one or more ports defined therein that enable fluid communication between an interior and an exterior of the work string, a sliding sleeve arranged within the sliding sleeve sub and movable between a closed position, where the sliding sleeve occludes the one or more ports, and an open position, where the sliding sleeve has moved to expose the one or more ports, a sleeve profile defined on an inner surface of the sliding sleeve, a wellbore dart having a body and a plurality of collet fingers extending longitudinally from the body, and a dart profile defined on an outer surface of the plurality of collet fingers, the dart profile being configured to selectively mate with the sleeve profile.

Abstract: A packer can include a mandrel having a longitudinal section, the packer being releasable in response to the section being severed, a slip support and a load transfer device that extends longitudinally across the section, the device being secured to the mandrel on one side of the section, and the device being secured to the member on an opposite side of the section. A method of constructing a releasable packer can include assembling a mandrel, at least one slip, a slip support and a load transfer device, the mandrel having a longitudinal section, and the packer being releasable in response to the section being severed. The assembling can include preventing relative longitudinal displacement between the device and the mandrel on one side of the section while preventing relative longitudinal displacement between the device and the member on an opposite side of the section.

Abstract: A well tool can include a chamber having a volume that changes when a member displaces, and a valve device that selectively opens and permits displacement of the member, and that selectively closes and prevents displacement of the member. A method of operating a well tool can include displacing a member, thereby changing a chamber volume, and then closing a valve device, thereby preventing displacement of the member. A well system can include a well tool connected in a tubular string, a flow passage of the tubular string extending longitudinally through the well tool, the well tool including a chamber having a volume that changes when a member displaces, and a shifting tool, a valve device opening and member displacement being permitted when the shifting tool engages the well tool, and the valve device closing and member displacement being prevented when the shifting tool disengages from the well tool.
