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

An oilfield valve having a body defining a throughbore and configured for controlling flow through the throughbore, wherein the valve has a disc connected to the body and movable between an open position and a closed position, and further wherein the disc has a top surface and a bottom surface, and defines a perimeter, wherein the disc is composed of a composite material having a facesheet and a core material adhered to the facesheet.

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.
