Abstract
A packer assembly for use in a subterranean well can include a seal element which swells in the well, a reinforcement in the seal element, and an extrusion barrier which displaces outward in response to swelling of an end portion of the seal element, the reinforcement being longitudinally spaced apart from the end portion of the seal element. A method of constructing a packer assembly can include positioning a reinforcement in a seal element which swells in response to contact with a fluid, the positioning including longitudinally spacing opposite ends of the reinforcement away from opposite end portions of the seal element, and installing extrusion barriers which radially outwardly overlie the seal element end portions.
