Abstract
A packer can include an end ring positioned proximate a seal element on a base pipe, and a gripping device which is compressed radially inward by a surface formed in the end ring, the surface encircling the base pipe. A method of constructing a packer can include positioning an end ring on a base pipe proximate a seal element, and radially compressing a gripping device in the end ring, so that the gripping device grips the base pipe, radial compression of the gripping device resulting from longitudinal displacement of the gripping device relative to the end ring.
