Abstract

A degradable downhole isolation tool for use in hydrocarbon well completion. The tool sets and isolates zones for fracking, and then degrades without leaving residual parts and without milling or introducing a new degrading fluid. The plug's mandrel and other parts are a solid polymer which hydrolyzes in aqueous downhole fluid to produce an acid which degrades degradable metal slips and other metal parts. The plug's seal may be degradable metal pedals or split rings. The plug is delivered to the well site as an interchangeable parts kit for adaption to the well's requirements.
