Abstract

A penetrator for a wellhead has an electrical conductor, a sleeve surrounding the conductor, a tapered seal ring compressed between the sleeve and the conductor, and a driver to compress the tapered seal ring and seal the bore of the sleeve. The sleeve can be ceramic and the seal ring can be adapted to deform against it. A tapered face of the seal ring can have a taper angle that is mismatched with respect to the angle of the sleeve that it engages, so that the tapered face of the seal ring does not align with the face of the sleeve. The tapered face can be coated with a deformable material. The mismatch between the tapered engaging faces can focus the force compressing the tapered seal ring between the conductor and the sleeve on a relatively small surface area of the tapered seal ring, which can form a tight seal against the sleeve.
