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.
