A valve system for use in a wellbore, comprising a side pocket mandrel having a main bore for alignment with a wellbore tubular and a laterally offset side pocket bore separated from the main bore by an internal wall, the laterally offset side pocket bore comprising a first receptacle for a first device and a second receptacle for a second device, the internal wall having an opening through which each of the first device and the second device is independently retrievable. There is also provided a side pocket mandrel, a hydrocarbon well and a method of operating a hydrocarbon well.

A tubular system includes a side pocket mandrel having at least one side pocket defining a device storage zone. A conductor extends along the tubular system to the side pocket. A stored device is arranged in the device storage zone.

A method of protecting a nipple profile of a downhole tool that forms a portion of a tubing string and that is exposed to through-tubing completion operations includes securing a single-trip protective sleeve to the tool so that the sleeve covers the nipple profile of the tool during the completion operations and dissolving the single-trip protective sleeve so that it breaks away from the nipple profile to expose the nipple profile for use.

A positioning tool can include a mandrel and an engagement device reciprocably disposed on the mandrel. The engagement device can include at least one engagement member and at least one landing dog. The mandrel can displace relative to the engagement device in response to engagement between the engagement member and at least one internal profile in an outer tubular string, and the landing dog can extend outward in response to displacement of the mandrel in a selected longitudinal direction relative to the engagement device. A system for use in a well can include a tubular string and a positioning tool reciprocably disposed in the tubular string. The positioning tool can include a landing dog that extends outward from a retracted position to engage one or more internal profiles of the tubular string, in response to a pattern of reciprocation of the positioning tool in the tubular string.

Kickover tools and methods of operating the same. The kickover tools are configured to engage a downhole component within a completion structure of a hydrocarbon well. The kickover tools include a tool body and a kickover arm that extends between a first arm end and a second arm end. The kickover tools also include an end effector that is operatively attached to the second arm end and configured to interface with the downhole component. The kickover tools further include an actuation mechanism that mechanically couples the first arm end to the tool body and is configured to selectively transition the kickover arm between a retracted configuration and an extended configuration. The kickover tools also include a data transmission interface and an attachment point. The kickover tools further include an imaging device configured to collect an image indicative of an environment proximal the kickover tool.

Plug and plug seat valves with selective orientation and engagement systems permit plugs to pass through a series of identically or similarly sized seats without the plugs mating with any of such seats before passing therethrough. Orientation systems may be employed in these valves such that the plug passes through each plug seat in a specific orientation in relation to the seat. The orientation systems may employ a steering track, such as rotational guide, to establish a desired relationship between features around the outer surface of the plug and the inner surface of the plug seat. Engagement systems may comprise one or more retractable elements on the plug which complement a receiving element of the plug seat. The orientation system may misalign the elements of the engagement system allowing a plug to pass an otherwise complementary plug seat.
