ABSTRACT:
A plug is provided which is specially adapted for statically setting a plug portion within an internal profile formed in a wellhead. In an illustrated preferred embodiment, the plug portion is set by application of fluid pressure to a running tool portion. When set in the profile, the plug portion is secured statically relative to the profile, thereby permitting advantageous utilization of a metal-to-metal seal on the plug portion. The plug portion includes features which maintain its set configuration in the profile. The running tool portion includes multiple pistons which enhance operation of the running tool portion. A disclosed verification tool provides an indication that the plug portion has been properly set.
