ABSTRACT:
A seal assembly for use in completion and production operations of a subterranean hydrocarbon well for sealing the annular space between the production casing and tubing, which assembly generally includes primary seal members having a circular, oval or elliptical shaped cross-sections, and secondary seal members having convex sections for abutting the primary seal members. The assembly further includes retainers on the tubing which define the seal bore into which the seal members are positioned, and a polished surface on the casing for allowing movement of the seal members against the casing.
