Abstract

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.
