摘要： A downhole tool for a wellbore and method of assembly. Components of the tool include a load member, one or slip members, one or more compression members, and a sealing element between the compression members mounted on a mandrel. The components are designed to prevent pre-set of the tool in the wellbore and facilitate removal of the tool from the wellbore.

摘要： A setting tool for setting frac plugs and the like can include a mandrel having a chamber for housing expandable gas and a gas port in fluid communication with the chamber; a firing head secured to the mandrel for igniting a power charge to generate pressurized gas within the chamber; a barrel piston housing the mandrel and connected to a sleeve for setting the frac plug; and an expansion region defined between the mandrel and the barrel piston and receiving the pressurized gas which exerts force to cause a stroke of the barrel piston over the mandrel as the expansion region expands axially. The setting tool can include various features, such as certain gas bleed systems, an enhanced shear screw assembly, a bleed port and plug assembly, a scribe line, a particular gas port configuration, a liquid escape conduit, no-shoulder barrel configuration, and/or a low-force design for frac plugs.

摘要： An electrical connection system for providing an electrical signal to a detonator of a perforating gun is provided. The system includes a tandem sub operatively coupled to a gun housing and having a sub body having a bore defined therethrough, a bulkhead assembly having a bulkhead electrical connector securable within the bore, and a printed circuit board assembly. The PCB assembly includes a cartridge having a connection bore adapted to receive the bulkhead electrical connector and define a sliding connection between the cartridge and the bulkhead assembly, and an addressable switch located within the cartridge body and in electrical communication with the bulkhead electrical connector. The detonator is located within the cartridge body and is in electrical communication with the addressable switch. The bore, the bulkhead electrical connector, the cartridge and the detonator are concentrically disposed relative to one another and extend along a common axis.
