A piston is slidably movable axially inside the housing and defines an upper and lower pressure chambers within the housing. A power charge is disposed in the piston. A crosslink sleeve supported on the setting mandrel is coupled to a crosslink key that extends into a slot in the wall of the setting rnandrel, such that rnOvernent of the crosslink key along the slot also rnoves the crosslink sleeve axially relative to the mandrel. To actuate the setting tool, the power charge is ignited to increase pressure in the upper pressure chamber, thereby exerting an axial force on the piston to directly push the crosslink key, along with the crosslink sleeve, to shift downhole relative to the housing. The shifting of the crosslink sleeve sets the downhole tool.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for limiting load on host servers that implement a social messaging platform. An example user device sends, to a platform comprising a plurality of host servers, a first request. The request is directed to a first endpoint. The user device receives, in response to the first request, a first error that indicates that the first request was not processed. The user device determines a back off time and places subsequent requests to the platform that are initiated before the back off time elapses and that are directed to the first endpoint in a back off queue in an order in which the subsequent requests are initiated. The user device sends, to the platform, the requests in the back off queue after the back off time has elapsed, until the back off queue is empty.

A dart for effecting wellbore operations has an inactivated position and an activated position wherein the exterior profile of the dart is changed when the dart is activated. The change in profile may be achieved by moving (for example, rotating) a portion of the dart relative to the remaining portion. When inactivated, the exterior profile allows the dart to pass freely through a valve. When activated, the dart cannot pass through the valve because the changed exterior profile is caught by the interior profile of the valve. Once caught, the dart creates a seal to open the valve when fluid pressure above the seal is increased. The dart can thus be used in multiple stage applications with valves having seats of the same size so that the dart can be selectively activated to engage a desired valve seat.

The flow passage may be positioned tangentially in the port sub. The breakthrough time of the dissolvable barrier may be preconfigured by providing one or more thinner areas therein and/or placing a corrosive material in the port assembly.
A dissolvable pressure barrier comprises a body having metallic dissolvable components, a power source, and a connector that is shiftable from a first position to a second position when a pressure greater than a predetermined load is applied to the pressure barrier. In the first position, the connector is electrically insulated from the power source. In the second position, the connector is in electrical communication with the power source, the metallic dissolvable components, and the casing of the wellbore, thereby forming an electric circuit wherein a voltage is provided by the power source and the dissolution of the pressure barrier is accelerated by an anodic process. The metallic dissolvable components may be coated with a low activity metal to assist with the dissolution process.
