Abstract

Disclosed is a drag block assembly for use with a downhole tool in a subterranean well, such as packers or bridge plugs. The drag block assembly comprises a generally cylindrically shaped sleeve and a block element. The block element is mounted to the sleeve such that it can radially slide. The block element is outwardly biased from the sleeve by an electromagnetic element.
