Abstract
A degradable plug device for a pipe prevents fluid flow through the pipe until the plug device has been removed from the pipe. The plug device includes a body which is at least partially of a degradable material. The exposed surfaces of the degradable plug include a protective layer thereon. The body includes a chamber therein. The body is disposable in the pipe to prevent fluid flow through the pipe. The plug is adapted to undergo a degradation initiation operation such that well fluid is able to enter the chamber to initiate corrosion or dissolution of the body from inside the chamber. The plug is useful for temporarily blocking a pipe within a well to control the flow of fluids or to actuate tools within the well.
