Abstract: Degradable downhole tools, tool components, and balls are formed from a polyvinyl alcohol (PVA) compound. The PVA compound exhibits strength and elasticity properties that are comparable to existing degradable downhole polymers and further exhibits degradability properties that are superior to existing degradable downhole polymers. For different components, the PVA compound may include a reinforcing material such as fiberglass. A plug for use in a wellbore conduit may include a sealing element that is formed of PVA compounds of various types.

The PVA compound exhibits strength and elasticity properties that are comparable to existing degradable downhole polymers and further exhibits degradability properties that are superior to existing degradable downhole polymers. For different components, the PVA compound may include a reinforcing material such as fiberglass. Usage of tools, tool components, and balls formed from the disclosed materials eliminates the requirement that such equipment be drilled out after use as the PVA compound quickly degrades in standard downhole fluids.
Abstract: A downhole tool or component, such as a hydraulic fracturing ball, may have a base body having an outer surface. The outer surface of the base body may have a lapped coating thereon. The downhole tool or component may be made by lapping the outer surface of the base body with a lapping slurry. The downhole tool or component may be used in downhole applications, such as hydraulic fracturing, and may resist degradation upon exposure to fluids, such as production fluids.
