Abstract
Dissolvable thread sealants are useful for forming a pressure-tight seal between dissolvable threaded components, particularly in downhole tools. A film of the dissolvable thread sealant can be formed on the threads of dissolvable threaded components. As the dissolvable threaded components are exposed to fluid under the appropriate conditions and begin to dissolve, the thread sealant becomes exposed to the fluid and, likewise, dissolves. Embodiments of the dissolvable thread sealants are made using polyvinyl alcohol (PVA).
