Abstract
There are disclosed several embodiments of a well tool having a slip assembly which is adapted to grippingly engage a cylindrical surface within a well conduit, and which includes a sleeve carried by a body adapted to be lowered into the well conduit so as to dispose a relatively high friction surface about one side of the sleeve opposite the cylindrical surface. The sleeve is split about its circumference and has end edges which extend at an angle with respect to the axis of the sleeve and are arranged to slide over one another as the sleeve is caused to move between expanded and contracted positions into and out of gripping engagement with the cylindrical surfaces.
