Inventors:

Thomas E. Upton - Garland TX

Assignee:

Dresser Industries, Inc. - Dallas TX

International Classification:

E21B 3312

US Classification:

166120

Abstract:

A seal assembly for a valve in a mechanical setting retrievable and pressure balanced packer has a valve seal mounted on a bushing mounted around a mandrel joined to an anchor and enclosed within a balance chamber housing. The valve seal is retained between the bushing and an overlapping coaxial face seal retainer such that only a relatively small portion of the face seal ring will contact the seal surface of a valve seat on the packer.
