A panel mounting device base and kit therefor are described herein. The described base comprises: a lower member, an upper member, a surface fastener, and a connecting fastener. The profile of the lower member and the profile of the upper member are identical, and the lower member and the upper member are rotated about its longitudinal axis 180 degrees relative to each other and attached to form the base. The base is secured to a surface, and the base receives a panel mounting device to retain a panel.

Panel mount base

A component of a slip assembly is formed by rolling sheet molding compound into a rolled charge. The rolled charge is positioned in a compression molding press and compressed to produce a molded element. The molded element is removed from the compression molding press and can be machined for use as the component of the slip assembly. The component can be a slip segment or can be a cylindrical body for the slip segment. The compound layers in the molded component can be oriented in a number of different orientations in the component and can increase the overall strength of the component.

Molded composite slip of sheet molded compound for downhole tool

A downhole tool, such as a fracture plug used during a fracture operation, installs in a downhole tubular, such as casing. The tool has a mandrel with a sealing element disposed thereon between uphole and downhole ends. Slip assemblies on the mandrel can be moved to engage the downhole tubular. When the tool is used as a bridge plug, the uphole assembly supports the sealing element compressed, and the downhole assembly supports fluid pressure downhole of the tool. The slip assemblies have inserts composed of at least two materials that are different from one another and are geometrically separate from one another. In addition or as an alternative, the slip assemblies can be composed of at least two different materials that are geometrically separate from one another.

Inserts having geometrically separate materials for slips on downhole tool

A downhole tool, such as a composite bridge plug, has a packing element disposed on a mandrel of the tool adjacent an activating element, such as a cone and slip arrangement. The packing element includes a packer and at least one backup ring. The packer is composed of packing material and is compressible on the downhole tool at least in part due to the activating element. The at least one backup ring limits extrusion of the packer. The at least one backup ring is molded into the packing material at one end of the packer adjacent the activating element. Preferably, each end of the packer has at least two backup rings molded therein, and slots in the adjacent backup rings are preferably offset at the ends.

Flow resistant packing element system for composite plug

A slip assembly for a downhole tool, such as a composite plug, has a slip body and at least one insert. The slip body has an incline at one end that interfaces with an inclined surface of a cone. As this occurs, the slip body is pushed away from the tool's mandrel against a surrounding casing wall. The insert is disposed in the slip body with the axis of the insert angled away from the cone. In particular, the insert's axis is preferably angled normal to the slip body's incline and the inclined surface of the cone.

Non-metallic slips having inserts oriented normal to cone face

A device and method for use is provided for grippingly engaging a tubular, in particular for gripping a wellbore casing. Drillable bridge plugs may use hardened buttons or other slip arrangements and materials that may be susceptible to damage when the bridge is being run into the wellbore. It may be desirable to protect the slip ring or the hardened buttons by shielding the buttons during run-in or by providing a standoff device so that the buttons may be prevented from contacting the casing until desired.

Standoff device for downhole tools using slip elements

A downhole tool, such as a fracture plug used during a fracture operation, installs in a downhole tubular, such as casing. The tool has a mandrel with a sealing element disposed thereon between uphole and downhole ends. Slip assemblies on the mandrel can be moved to engage the downhole tubular. The uphole assembly has inserts composed of ceramic material, and the downhole assembly has inserts composed of a metallic material. When the tool is used as a bridge plug, the uphole assembly supports the sealing element compressed, and the downhole assembly supports fluid pressure downhole of the tool. In one particular embodiment, the metallic material is a powdered metal material, such as a sintered-hardened powdered metal steel having a balance of iron, an admixture of carbon, and alloy components of molybdenum, chromium, and manganese.

Downhole tool having slip inserts composed of different materials

A downhole tool, such as a packer or liner hanger, has a mandrel on which slips are disposed for engaging a surrounding tubular downhole. When the tool is being run in or out of the hole, at least one magnetic component magnetically retains the slip adjacent the mandrel so the slip can be held away from the surrounding tubular. When the tool is set downhole, the initial magnetic retention can be broken, and the slips can be moved away from the mandrel to engage the surface of the surrounding tubular.
