A slip assembly for anchoring a subterranean well tool, such as a packer or bridge plug, along the inner wall of a conduit, such as casing, against movements in at least one direction. As a series of radially aligned slip elements move from contracted to expanded positions, a continuous radial inwardly urging bias is applied against the slip elements to permit the slip elements to move to the expanded position in a substantially uniform plane of expansion. A subterranean well tool includes an elastomeric seal and the slip assembly.
